Title: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 09, 2012, 07:08:04 AM
Any one that feels there router is over heating or hotter than normal and can collect router temperature numbers and data, please post here. If you can provide the following:
Please post number in Fahrenheit.

Room temp where router is located:
Temp at IDLE:
Temp with only 2.4Ghz data flow:
Temp with only 5Ghz data flow:
Temp with both 2.4Ghz and 5Ghz data flow:
Temp with wired LAN, 2.4Ghz and 5Ghz data flow:

Any of these if possible.

Thank you.

Furry

Not sure how accurate the ambient temp device I had since I can't find a more accurate one. I'll look for a laser temp device soon and re-test, so my data isn't the best. I just put the device right on top of the router and let it sit there.

Room temp where router is located:
68-70
Temp at IDLE: 80-84
Temp with only 5Ghz data flow: 90-94
I watched a DVD movie on my Mac Book Pro on 5Ghz streaming the video from a DIR-685 in AP mode, that was wired to the back of the DIR-857. Temp never rose above 94. I streamed the movie for about 1 hour before stopping. Mac Book was 3 feet from the 857.

I'll try and test 2.4Ghz and both this week if I can.

Anyone interested in a Laser Temp guage, check out Amazon. (http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dtools&field-keywords=Thermometer+Gun)

Had a hard time finding a laser temp gun around here so I've ordered one from Amazon.com.  Hopefully it will arrive by the end of the week.  Until then, I won't be pushing the router too hard.

My temp gun came in today.  Ambient air temperature is 20C.  The bottom of the router from sitting on a cool stone surfaced window ledge is 34C with very little traffic going through the router and nothing being used over either WiFi spectrum.  I wouldn't call that promising as a starting point.  I will post some more results when I can sit down and do some testing. 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 17, 2012, 12:02:54 PM
Please keep us posted when you get results for the items listed in the OP.

I ordered a gun today from Amazon and should be here this Friday. I'll play with mine this weekend and post more accurate results.

Can you post both temp numbers in C and F for us non C users?  ::)

Thank you.

The HDE gun at your link is the exact one I ordered. 

5GHz only streaming of Netflix to my notebook connected to my TV reads 46.7C.  This reading was taken mid streaming on the bottom of the unit while the movie is still streaming.  I took more than one reading to ensure it was consistant.  The temperature of the top of the unit is 37C. 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 17, 2012, 12:57:08 PM
I ordered the same gun. Let us know how it works.

Wow, 116F, thats kind of high. Again not sure what the specs are and probably wont know. I didn't get a chance to measure the bottom, I will this weekend.

98F is not to far from what I was seeing at 94F while measuring the top of the router. Hmm.

Please post 2.4Ghz results if you can.

Thanks for the feedback.
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on October 17, 2012, 01:58:02 PM
With both radios enabled but just streaming on the 2.4GHz channel.  Reading from the top gives me 39.1C during streaming.  The reading from the botton is 48.5C after just under 5 minutes of steaming.  I decided to isntall Steam on my notebook to hammer it a little better.  The top of the router while the 9GB download has been progressing for about 5 minutes is 41.1C.  The underside of the router was a consistant 49.3C in the middle of the bottom.  Holding the trigger in on the gun allows me to move it around to find the hottest spot while taking realtime readings.  Basically, the middle of the bottom slightly closer to the back was the hottest point and it stayed consistant over a 30 second reading all but the decimal which only fluctuated by .2C.
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 17, 2012, 02:03:07 PM
Awesome info.
Let us know what temps are if you can do data flow on both radios at the same time and If you can, can you do streaming to a wired device as well with both radios going and flowing?

120F is definitely hot. Wow. I presume this is the closest point between the bottom of the case the CPUs possibly.
102 is warm at the top.

I hope to provide details on mine Friday.

Thank you for the feedback.

Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on October 17, 2012, 02:12:18 PM
Just took readings on the top and bottom again.  When looking down at the router, about an inch down on an angle from the left botton of the D-Link logo yields 42C.  On the bottom, holding the trigger around the center but slightly closer to the front yielded 53.9C.  That is only using the 2.4GHz radio and a little web browsing on my wired desktop. 

To test it all at once, I'm going to stream Netflix on my Wii over 2.4GHz, Download another game over 5GHz to my notebook, and load up an MMO on my desktop.  Hopefully this doesn't kill the router. 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 17, 2012, 02:18:05 PM
Good test, Ya I was going to mention on testing the temp thru the air vents looking down at the internal components. Good catch.
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on October 17, 2012, 03:55:16 PM
Going through the vents definitely is where I'm poining when taking different readings on the bottom.  With another 8GB game from Steam (Transformers: FoC) downloading over 5GHz, Knight Rider streaming over the 2.4GHz via Netflix to the Wii, NASA TV running in the background on my desktop along with the Transformers Universe trailer also playing away to keep the desktop pushing some bandwidth.  The temps are as follows.  

Top left corner: 39C/102.0F
Top Center (about an inch off on an angle down and to the right of the K in D-Link): 44.5C/112.1F
Top Center (close to the back ports): 40.1C/104.18F

When taking readings on the bottom, the router is upside down.

Botton center through the vent: 54.8C/130.64F
Bottom left (third vent from the top and about an inch or so from the left): 50.1C/122.18F
Botton Vents (1 through 4 on the right side of the unit about an inch and a half in on each): 51.2-5C/124.7F

Results are after about 15 minutes of the mentioned use.  Neither WiFi radio or wired ceased to work.  I still  have everything running as I type this post and will leave it running until the end of the Knight Rider episode unless something finishes early.  

Furry: Added F values.
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on October 17, 2012, 06:28:17 PM
I had let the tests go a full 48 minutes (the length of the Knight Rider episode).  I had to start a third game fordownloading by then but the temps stayed pretty much around what I listed in the previous post.  No wireless drops, resets, or anything.  The router definitely gets hotter than I would say it should though.  All chips are not created equal so I consider myself lucky mine didn't crap out.  Better cooling of the internal components with something copper and better venting of the heat need to be addressed! 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 18, 2012, 07:01:10 AM
Awesome data collection. Ya, seems that this could be running a bit cooler.

I should get my temp gun in tomorrow and will do the same testing.

I'll get this to D-Link.

Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 20, 2012, 04:59:33 PM
Here are my results:
HDE temp laser gun
Values are in Fahrenheit
Temp readings are of hottest areas on top and bottom of router. Usually right hand side, just about a 1/2 inch from the vent louvers on the smooth surface and about 2 inches from the right side edge of the router.

Room temp where router is located: 70-71F
Temp at IDLE: Top - 111F/ Bottom - 120F
Temp with only 2.4Ghz data flow: Top - 109-111F/ Bottom - 120-122F
Temp with only 5Ghz data flow: Top - 109-110F/ Bottom - 120-122F
Temp with both 2.4Ghz and 5Ghz data flow: Top - 108 - 111F/ Bottom - 122-124F
Temp with wired LAN, 2.4Ghz and 5Ghz data flow: Top - 110-114F/ Bottom - 122-123F
Inside vent louvers: 112-114F


Temp test with only 2.4Ghz data was streaming DVD movie on HDD from DIR-685 connected via wired to DIR-857 to a Mac Book Pro using OSX 10.6.8. Wireless and DHCP services disabled on DIR-685. Just working as a NAS device.

Temp test with only 5Ghz data was streaming DVD movie on HDD from DIR-685 connected via wired to DIR-857 to a Mac Book Pro using OSX 10.6.8.
 
Temp with both 2.4Ghz and 5Ghz data was streaming DVD movie on HDD from DIR-685 connected via wired to DIR-857 to a Mac Book Pro using OSX 10.6.8 via 5Ghz, while Boxee Box was streaming on 2.4Ghz DVD movie files from my file server that is wired Gb Lan connected to the DIR-857.

Temp with wired LAN, 2.4Ghz and 5Ghz data was streaming DVD movie on HDD from DIR-685 connected via wired to DIR-857 to a Mac Book Pro using OSX 10.6.8 via 5Ghz, while Boxee Box was streaming on 2.4Ghz DVD movie files from my file server that is wired Gb Lan connected to the DIR-857. Xbox 360 was streaming Netflix movie via hard wired LAN cable connected to the DIR-857.

Over all, never saw much Top temps get over 112-114F on the top of the router and the bottom always seemed to maintain nothing over 122-124F. Took me about an hour and a half to test as I graduated from a single streaming device to adding all 3 for just this test. Taking readings every few minutes to see if router temps would fluctuate greatly. They seem stable for the most part and didn't see any router problems at all. I'm wondering if there could be Mfrg issues or differences in some routers.  ???

Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on October 24, 2012, 01:26:26 PM
just saw this thread.  I think my first router died of heat stroke.

My replacement has done the same thing where it would lock up, give me no internet, but say i was connected just fine.

So i DIY'd a 120mm fan powered off a 12v ac adaptor underneath it.  Runs MUCH cooler just based off of touching it.  Has not become unstable again.


For what its worth the manual lists this as the operating temp range.

Operating Temperature
•    30ºto 104º F (0ºto 40º C)
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 24, 2012, 02:11:39 PM
Good catch on the manual findings. I'm wondering if our routers have been exceeding these temps due to something in FW. I have forwarded this on to D-Link. Would be helpful if you can collect any temp values if possible. The more data we gather the more we can't provide D-Link with a reason to review this and hopefully come up with a solution. External fans are a good work around though.

Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on October 24, 2012, 02:13:55 PM
i can post pics and a simple DIY if wanted.  Its very very easy.

edit: ill see if i can find a heatgun from somewhere.
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 24, 2012, 02:24:07 PM
Kewl,

Please collect some of the temps listed for the tests in the OP. With out and with the fan going might be good too. Mine isn't running a fan...yet. Makes me think maybe I need to invest in one.  :-\
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on October 24, 2012, 05:11:32 PM
itll be maybe 5-10dollars for the fan and another 6/7 for an AC adaptor.
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 24, 2012, 05:16:30 PM
I I can get a power adapter at Radio Shack long with a fan. Might find me a realy quiet one online some place too.
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on October 24, 2012, 06:11:01 PM
youll want to match the input amps to the amount the fan can take though.  each can handle only so much.

is the adaptor im waiting on to arrive.  http://www.ebay.com/itm/New-AC-power-Adapter-supply-12v-35a-4W-MU04-8120035-A1-/220699212390?forcev4exp=true&forceRpt=true#ht_2203wt_1163 (http://www.ebay.com/itm/New-AC-power-Adapter-supply-12v-35a-4W-MU04-8120035-A1-/220699212390?forcev4exp=true&forceRpt=true#ht_2203wt_1163)



This is the fan ill be running on it.

currently im running some case fan that was too noisy that i replaced that has a max of 200ma or .2

the AC adaptor i wired is an old pelican one that went to a multi AV switcher hub.  it only outputs a max of  100ma or .1

Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 26, 2012, 01:18:45 PM
Even with your cooling fan?

Can you do the following test? Turn off both radios and see if the router locks up. Then turn on 1 radio, leaving the other one OFF. Does it lock up. Switch radios and test.

Feel like teamviewer?
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on October 27, 2012, 03:58:20 PM
disabled one radio the 5ghz.  have to leave the 2.5 on for the wife or i will get angry looks.

also whats teamviewer?
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 27, 2012, 04:15:20 PM
Ok, let us know what happens. Need to find a time with the wife isn't using 2.4Ghz if possible and test with out it.

Teamviewer is a remote application that allows designated persons to view your desktop, routers settings and such. Nice application for remote help and file xfers.

Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on October 28, 2012, 12:16:49 PM

Title: Re: DIR-857 Temperature Data Collection
Post by: BiggShooter on November 04, 2012, 06:15:14 PM
Well, my idea of hooking up a car radiator didn't work.  I resorted to the next best thing!  Two crayola markers along the bottom (front / back).  This allows the DIR-857 to "breath" from the bottom as well!  So far, so good!  Seems to be running "cooler".

Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on November 05, 2012, 02:37:25 PM
Mine has yet to die but I like my apartment cool.  Furry's temps are lower than mind but still over the manuals optimal temps that the one user posted.  I have had a few wireless stalls though under heavy streaming.  If it starts to do this when I game on the Wii or my notebook, D-Link is going to be a call from qa very unhappy customer insisting on a replacement with a revision A2 that either comes with some sort of active cooling ir is tested under full load to run at temps that don't load to hardware failure. 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on November 06, 2012, 07:41:50 AM
Ok, I forwarded this on to D-Link. I would keep a external cooling option available and handy. I am concerned that the temps are higher than being reported by the user manual.  :-\
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on November 06, 2012, 07:41:41 PM
so i reset the router to factory defaults (never did after installing the firmware last time) seems to be happy once again.

The cooling fan does indeed make a LARGE difference to how warm it feels to the touch.  overall pretty happy with the 120mm fan + 100mA imput, might need to use my 300mA during the 100 degree summers though.

current uptime is several days without a restart now.  Temps have also gotten much cooler.
Title: Re: DIR-857 Temperature Data Collection
Post by: kargo27 on November 07, 2012, 06:50:30 AM
Just to interject my data here:

1. Ambient air temp where router is located is 76F.  Without cooling pad, 857 temp under a good load is 117F.  Will measure with cooling pad later but doing some non-cooling pad testing today.

Thinking ahead and the best cost colution for a business instead of recalling and RMA's each and every one of these out there.  I hope D-Link is looking at producing a little router cooler that draws power through a USB pass-through.  I am not far off calling their tech support to inquire as to what their solution is for this design flaw.
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on November 07, 2012, 07:18:32 AM
I presume that D-Link would not think of a cooler for there products. Is a good idea though.

I highly recommend that you do call in. Calling in and contacting them helps get this issue more visibility on there side and helps them understand our concerns as D-Link users of there products. I would go up Level 2 to start. Refer them to here.

I would also be patient as well, if there is a problem, the fix could be a ways out and would not be happening overnight.  ;)

Let us know how it goes.

I e-mailed support with a link to this thread.  I figured that would be much easier than running through all of what has been already said and to show that this issue doesn't just affect myself. 
Title: Re: DIR-857 Temperature Data Collection
Post by: FurryNutz on November 07, 2012, 10:04:32 AM
FYI, I have tried e-mail support and along with others, the feedback we get from email always seems to direct us to calling phone support. I have attempted this twice with email support and both times I get nothing more than the problem is too advanced and phone support is needed. I recommend calling on the phone and going to level 2 or higher.
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on November 07, 2012, 11:55:55 AM
Okay.  Will do!

Edit:  D-Link RMA is hilarious!  They aren't aware of any temperature issues with this device.  What's the point in having a forum is they are too lazy to monitor it?!

Hmm, seeing as how everyone seems to be having temp issues and I saw someone posting their laptop cooling pad solution on the front page I may as well post up my solution. I noticed my router was feeling very hot and I have had constant issues with my 827. I built this a couple months ago.

Its just a 120mm fan mounted to some cut MDF and spray painted black. I cant recall the temp difference I recorded, but it was significant. My only mod left to do is add an inline variable controller or resistor to turn the fan speed down a bit as it whirs pretty good at full power.

That is a SWEET cooler!  What do you figure the cost to build was and could you link where you got the supplies if you have time?  I like this because most good fans like that have a 5 year or more life expectancy on the motor bearings.  I would build one just because it looks good!

I think I have a project this weekend!   ;D
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on November 08, 2012, 05:43:50 PM
Here is my DIY.  Should cost you less than 15.  will cost you less than that if you already have a spare fan.

Find an AC adaptor.  This is one I bought off ebay for ~7.00.  Make note of the mA rating that it outputs.  This is important because you have to match it to the max that the fan can handle.  This isnt the one I ended up using.  Put out too much power to the fan made it a tad loud.  Reccomend something that puts out 100mA or maybe a little more.

(http://imageshack.us/a/img10/2658/photo1wop.jpg)

The Fan im actually using.  Not its max input of .20 AMP
(http://imageshack.us/a/img15/1741/photo6mam.jpg)



Now the fun part.  cut the end off the ac adaptor (that little metal round part) so that you just have wires on the end.  Strip them offf and the fan wires off.

They should look like this.

(http://imageshack.us/a/img831/4008/photo3ys.jpg)


Match the red wires to red black to black.  If it doesnt have red on one or whatever, any positive wire will have something like this gray striping on the wire to indicate its positive.

(http://imageshack.us/a/img43/6237/photo2his.jpg)


Line them up like this...   ||  and twist them together.  Electrical tape around them and taadaa the hardest part is done.

Now for airflow under the fan just use the screws that came with it or just any screws that will fit and you get this...

Mine was dirt cheap, I bought the fan on sale a few months before building the cooler for 4.99 at ncix if I recall correctly. I was going to do the power adapter approach like skraeling above me there but ended up leaving the standard fan connector on and just plugged it in through the back of my server (its always on) into the motherboard fan header. I had bought an account adapter and had a old usb cable handy I could have wired it too. This saved me 5 minutes of soldering and trying to match amperage etc. The mdf, screws, and paint I had laying around. The legs were cut dowel that I receessed a hole in the mdf for and glued on. I don't have any build pics but it is fairly easy diy. Just sketch the pattern of your fan on the mdf and cut a hole. I'm happy with it, it cools well and looks good to boot. I show all my friends my server and cool router and cooler. None of them are into computers and all look at me like I'm crazy haha.

Great posts, dudes.

I unfortunately don't have a wood router but may have access to one.  The hardest part for me would be to cut and router that 120mm hole.  I'm mechanically inclined but a carpentry noob.   ;D

If I can't go the Slimline route I'll go the Skraeling one.

I'm going to use a power adapter for the fan and the fan is rated at 0.38Amps.  So, what size amp power adapter do I need?
Title: Re: DIR-857 Temperature Data Collection
Post by: skraeling on November 09, 2012, 12:21:01 PM
380mA or under.  Just FYI though my fan with a 300mA was somewhat noisy.  Id recommend something around 100 to 150mA.  Or if you can wire in a fan speed controller (which i havnt looked into yet).

You dont need a router to build what I did. You can use a hand saw to cut the generic rectangular shape with some patience to make it look nice. I drilled a hole in the centre of the board with a 3/8 drill bit then used a jigsaw to cut out the hole. However, if you dont have access to a jig saw you can draw the circle on the board and then use a drill with a small bit to drill circles as close together as possible then knock the centre out. Then its just a matter of filing the edges to clean it up with a round file. If you have a dremel, most of them have an edging bit that looks like a drill bit but is meant for moving laterally through a workpiece. That tool would easily cut a nice circle :) A little creativity and you can build something far nicer then I did with not too much effort or time.

It is a fun project though, although we may be a bit of a sad community building router coolers lol.

That's definitely a worth while improvement.  I have been playing around with mine and a laptop cooler.  It does stop the wireless from crapping out.  I have an RMA open but I might just consider letting it slide since support stated they were unaware of any temperature issues.  At least running at normal temperatures (with active cooling), it's reliable.

So I'm back to testing your 857 using ALL modes on WiFi, Short GI and HT20/40 is OFF and disabled. Turned off the cooler. Game play was ok however not sure if H4 servers and players were not working well, had a couple of games where single was in the Red. Woke up this am and iPhone had a good connection from what I could tell.

I'm wondering if maybe you should be using ALL modes instead of specific G and N mode since you have a couple of walls in between and more distances to cover.

Temps went up to about 108F this morning before I left. Ambient room temp was 65. I'll turn on my 2 APs tonight or tomorrow and test again. Alone, this router is working very well.

I have BO2 waiting for me at redbox after work so I'll be on tonight.  ;D

I don't know about that ambient air temp at 65.  Really, who keeps their homes that cold?  Also, you have to run the router for a week.

I purchased two Antec - Laptop Coolers from Best Buy a few years ago for my Xbox 360 and laptop.  I recently purchased a third laptop cooler as I wanted to try it with the DLink 857 and the Motorola SB6140.  Prior to using the Antec Laptop Cooler, both the 857 and SB6140 ran warm / hot (to the touch).

After placing the 857 and SB6140 on the Antec Laptop Cooler, both are now much COOLER (to the touch).  This does help with keeping both networking components from getting hot!

Here is the link to the type of laptop cooler I am using:

Yeah!  I've noticed that as well.  Too much heat is expected to escape from the bottom when hot air rises.  Clearly, someone wasn't thinking when designing the shell for this thing. 

I still have yet to hear back from D-Link about my replacement.  It is completely locking up under heavy use while sitting on a cool concret window ledge.  It's about 65F in here also so my room temperature shouldn't be an issue.

I would lower your Torrent seeds as it been know to hammer most any router. do a few at a time maybe. You might want to adjust your BT settings as well. BT is a major bandwidth hog.

Streaming video over 2.4Ghz or 5Ghz?

If your doing all this and BTg, I would try to BT wired or use 2.4Ghz if your doing it over WiFi, then stream via 5Ghz if you have clients that support 5Ghz.
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on December 13, 2012, 11:23:24 AM
My BT settings are set to use about a quarter of my bandwidth and nothing more.  My connection is 25Mbit down/10Mbit up.  I watch a lot of Netflix and Julu Plus as well as play the odd MMO.  When I had the first unit on its way to D-Link, I used the PowerLink Boost-N doing the same as what I do now, just without the luxury of a 5Ghz band to use.  That held up just fine under the same circumstances and normally I just use that in bridge mode to give me a better 2.4Ghz range and stability.

That's this (http://www.premiertek.net/products/networking/PL-APN.html), which was recommended back in the DIR-855 area to help deal with interference.  It works wonders but isn't bad as a stand alone router either.  I don't find I have interference issues not using that with the DIR-857.  I'm not too sure if the radio is just more solid for broadcasting or not but I can stream HD to my TV without any issues.  It's just when I start to do multiple things, the routers gets very hot and then becomes unreliable.  At idle, it's sitting at 33C on the top center and closer to 40C at the top rear (by the ports).

I would test with and with out this unit. If you test with this unit, Turn OFF The 2.4Ghz radio on the 857 and test again.

How far apart is this unit from the 857?
Title: Re: DIR-857 Temperature Data Collection
Post by: Syaoran on December 13, 2012, 12:46:14 PM
I have.  If I take the DIR-857 completely off the network and solely use the PowerLink.  I have no issues even under the heaviest traffic.  The DIR-855 is fairly solid but the radios in it seem to be extrememly sensitive to interference.  However, at short range, I have no issues running that solely.  Basically, the DIR-855 running with devices connected with about 6 feet of distance to ensure interference is at a minimum and it's solid.  Using the DIR-855 out at the cottage where there isn't anything to interfere.  It's a great device and I have much better range with it there.  Other than it being here in for testing, it's normally left up at the cottage.

Just listing what other routers I've tested under the same conditions.  Both radios are set to channels no one else withoin range are using.  I don't have any issues with the DIR-857 and interference.  It's just temperature under heavy use, which in most cases is over wireless 2.4Ghz and 5Ghz simultaniously or heavy network traffic wired mixed with wireless.

Well, for the 857, under load, please get a LT cooler and test again and see. I would test the 857 alone with out any other wifi going.

Are the WiFi settings on the 857 default settings or are you using specific modes? Does this happen if using single modes or Mixed G and N on the radios?
Title: Re: DIR-857 Temperature Data Collection

I just corrected my post on the heatsink in the DIR-857 found here (http://forums.dlink.com/index.php?topic=48474.msg195611#msg195611). Seems Dlink put their heatsink along the bottom of the router. To improve performance of cooling it might help to turn it upside down. Sounds crazy but I think it might help. Or if you stacking it on something so their is more clearance along the bottom.

With all of the testing I've done.  Stability goes out the window once the router hits 35C.  I haven't heard a single thing out of D-Link to address this either.  Even the beta firmware failed to provide any better results.

I don't have much data to add, but wanted to comment that I bought this router in late 2012 when the weather had cooled down. It had been perfectly stable since then but, now that the first hot/humid period of the summer has begun, I *think* I've been having temperature-related issues with the router.

The other day, one wireless connection kept dropping and reconnecting every 5 seconds or so, and I kept losing my wired connection to the router as well in a similar manner. I had another PC doing some heavy traffic.

The router did feel quite hot.

Turned off 5GHz, which didn't help much, wedged something underneath it to allow better airflow underneath, and then stopped the traffic on the other PC and after that the problem went away for the rest of the day.

It's in a basement, not enclosed, and on the top, open shelf of a mid-height wooden shelving unit. So, it maybe is a bit humid down there, but not much more than warm in terms of ambient temperatures.

It's fine now. The weather has cooled down. But this is pretty disappointing if heat was the cause... it was by no means an abnormal operating environment, and the router wasn't especially overworked (one active wireless connection well under saturation point, plus wired Internet uploads of about 1MB/sec, though using many connections).

With a router costing this much, I hope they didn't cheap out on heatsinks.

Not lon after D-Link sent me another beta firmware that didn't help with the various issues I was having with this router, I went out and bought an Asus RT-AC66U.  D-Link should take note because both are around the same price but I haven't had a single issue with the Asus since I bought it.

Any idea of how hot your 857 is getting?
What is the ambient room temperature?

Does shutting off options that are not being used like WISH, WPS help any?
What wireless modes are you using? Do Single modes like G or N effect anything?

Any other Wifi neighbors around? I only have few around me. All the measurements I took where with in operating temps.

Try using a fan or laptop fan placed under the 857 help any?
