I bought one of these for cooling testing for users reporting the 857 was getting hot:
http://www.walmart.com/ip/Onn-Laptop-Cooling-Pad/16794998

Well all too temps on that router. I couldn't get mine to heat up near what some others were reporting. I talked to D-Link and they said all temps we were reporting were with in spec. I presume this could be however I wonder about duration and were and tear on the router when it's constantly hot like that and over time, does it degrade?

I just posted my mod i did for my DAP-1533. I'm amazed that they used non metal heat sinks instead and he fixing of the sinks was bad as well. I know thats not used in the Amplify line however maybe the addition of some metal sinks could help here as well.

Keep us posted.

I have one of those chillers for my laptop, they work great! Mine is aluminum with a whole bunch of holes and some fans. Better then burning my legs!

Yes! Heat reduces the life of electronics significantly, but some components are designed to take it better then others. Silicone IC's have a breakdown temp, down remember the exact numbers but I think a 100C operating temp is pretty close, that is why I went ape with fans on my video card. Nvidia said 90C was OK, but still for how long? They are in the business of selling chips. MTBF is the term.

Well I just downloaded several gigabytes of data through the router, it is warm here today. My desktop my laptop via wifi and another desktop, I kept it loaded HARD for 45 minutes! Nothing, works great.

I wonder if maybe packet collisions were a problem since everything is on a Gigabit switch now? I don't know enough about Ethernet and Packet timing, but with as many bugs as Microsoft usually has, it would not surprise me!

I will keep an eye on it and next I will reload the firmware if/when it cacks again.....

I thought we had it, then it crashed 4 times in a row. Every time it would restart it would crash again. Below is what I captured from the logs, it is clearly shutting itself down, but why I have no clue...... Ignore the date, every time it crashes I need to reset the date.

Ok, lets disconnect everything from the 827 including the USB drive. I might even do a factory reset with only one wired or wireless PC connected and test this out with out any other devices connected. Maybe even try with out the ISP modem connected. Install a different router with out any wireless so you can still provide WiFi if needed.

Need to see if the router does anything with out being connected to the ISP modem and having other devices connected...then graduate connecting devices...

[Patrick533]

That is the weird part, no USB drive but I seen that in the log too.

I have to do Turkey day shopping when my wife gets home in 30 minutes, so I just turned off the WiFi for now, I do have a memory card in the router, I pulled that just for giggles.

I am finding the shutdown error all over the net when I Google it, the only fixes I have seen is a firmware upgrade. The DIR-655 had a pretty good history of doing this when it was new.

I will re-install the firmware in the morning or late tonight, might even pull my older router out for now.

Kind of weird, it usually happens the same time everyday. 

Modem logs are CLEAR!

Happy Turkey day! "I'll be back!"

[FurryNutz]

IF this is happening during the same timeframe of the day...could be interference or something on the net.

Keep us posted. I got to prep turkey tonight. I'll be around.

Cheers.

[Patrick533]

OK,

Reset factory defaults, wiped router via 30-30 method and installed firmware V1.02(it was at V1.04).

Only changed what I had to to get it online. No WiFi, auto time, IPV6, nothing.

I did change the DHCP renew from 1440 minutes(24hrs), to 999999, which is in like 2015 before it renews IP addresses.

So now I beat on it for a while!

So far it is working good, usually because I have had IPV6 installed windows wants to use that 1st to go places but it seems with this old firmware the 2-4 second wait is not present and it use IPV4 instantly. So no rush to turn V6 on!

All 3 of my kids will be here tomorrow, so by then I will have everything back online for them but I will still not change anything in the router. If that don't work and it starts it's usual crashing I will put another router inline and this will become my router ONLY for a few days. Too busy to take it completely offline during the Holiday. I'm sure I will have to print 100 pictures tomorrow!

I was thinking about just removing the top of the router before I go to all the trouble of cutting a hole in the case for a fan if it is heat.

The 1440 minute DHCP renew has me wondering, I always set it to 99999 but I stopped awhile back.

I have a AT&T Microcell that provides a cellular signal to my house via IP, it is part VPN and part IP transport, I wonder if that 1440 thing was fighting with that. I guess only time will tell.

Enjoy the Holiday!

[Patrick533]

Since I have reverted back to 1.02 I have had no problems for 24hrs.

I turned IPV6 back on this morning, so another day or two for that.

I had read some older posts yesterday. One person had went back to 1.02 and it cured his problem but he still got rid of the router because he could not run the latest firmware.......... Kind of like offing my PC because windows 8 stinks. I had even posted that I was running 1.04 with no problems in the same posts but I did NOT have any 5Ghz clients at the time. I just upgraded my laptop with a Intel 802.11AC radio 6 months ago and bought an android with 5Ghz around the same time frame. Before that I don't think I used the radios in the DIR-827.

That stupid 1 watt A/P sure was worth it's money, not a hiccup in several YEARS.

More to come.........

[FurryNutz]

I might put my 827 online and run it as well...even though I don't have IPv6 native ISP support here so I usually set Local Only on my routers...v1.04 loaded here.

Keep us posted.

[FurryNutz]

Oops, for got i had loaded v1.05. 
http://forums.dlink.com/index.php?topic=53218.0

I have it online now and will run some tests on 5Ghz. Got a DAP-1533/Xbox 360 and my Mac Book Pro connected.

[Patrick533]

Well that pretty much concludes that!

3 firmware versions, 3 complete wipes and whenever the internal WiFi is on it crashes, usually several times in succession. It actually went into a crash-restart loop last night, the only way I could get it to stop was by quickly turning off the WiFi and saving it before it crashed again. 18 months, that is a record for me. I tried to contact D-link to buy a new WiFi module but they can't fit that into the script I guess.

I was just running the WiFi with no clients attached. I guess it really may not even be the radio module, could be the PCI interface. Either way with all the heat in that general area, 4380Hrs MTBF. Maybe they sent me a refurb after the DIR-825 fiasco, that would actually make more sense.

Getting bored with the whole IPV6 thing, all my previous routers are several years old in a box and they all still work, the only reason I replaced them was to add functionality, parental controls, printer ports, etc......

I have a couple of ways I may go next, a PC with Unix, 2 nic cards and router/nat/firewall software or the router my kid(s) is pushing with the dual cores(802.11AC like my notebook, 1750?). Probably be cheaper electricity wise to go with the router, 60 watts vs a minimum of 200 watts.

Thanks for the help, but me thinks this box is beyond help! Hopefully the router with the WiFi OFF will be stable for a while longer.

[FurryNutz]

Only thing I might do is to test the 827 in a different environment. Say a friend or families place just to see if a different environment could result in something different. I agree, I think the Wifi on the 827 is probably toast. I've been using my 827 since you posted about yours. Seems to be doing well however duration of use is much lower than what I presume yours was and being in a different environment, could have different results. Still makes me wonder if your 2.4Ghz blaster could have had any impact on the 827...

If the router portion works, shut off the Wifi on it and connect up a DAP model AP like a 1525, 1533 or if you want AC, connect a AC Wifi. Would make a simple work around and upgrade too.

[Patrick533]

Well,

We are in a zone to where if I had a spare card I could rule out the WiFi card being bad. But unfortunately both WiFi bands are also located in a ISM band which makes noise common, such as cordless phones or medical devices. I would actually consider my fairly high end 5Ghz cordless phone system a possible problem but the whole reboot loop thing has me kind of baffled. The WiFi router should just change channels?

The kid is a high packet rate user but not so much data, it usually only happens when he is online until the night before last and I was the only one home. I told the kids last night, do we really want to go spend 200 bucks on a new router right at this second. The WiFi is off and so far the router is stable, everything else can run on the 2.4Ghz high power AP, it might be a good idea to wait. I don't really want to give up my IPV6 though it is really not necessary.

Then the time thing, it always seems to do it around the same time, but then again that is when it is being used the heaviest. Maybe the base that is a stone throw from my house is resetting everything. We actually have another base that is about 60 miles(Camp Pendleton) away that warns people in the newspaper that their RF stuff is going to go wacko for a couple of weeks out of the year.

For now, I think I will just label it as FM, the last word is "Magic", use your imagination for the 1st. I have seen things in electronics and RF especially that just simply defy logic still after 35 years. Looking at the logs from last nights gaming session, nothing! Rock solid!  (Scratching head!!!)

Unless a router shows up, I am not going to buy one or solicit one. My wired PC/work/gaming station is once again rock solid.

BTW, I just went to the D-Link home page to look at those AP's, it appears they are full on IPV6 now(I have a little Firefox widget that tells me 4/6/mixed).

 

[FurryNutz]

I would run a test of that router in a different local if possible at some point. I'd be open to helping you out with that? 

Did you try v1.05? I presume you did.

Ya, seen some odd things in my experiences with Radio and WiFi over the years. For the most part things are fairly standard, however in some case, may not be. 

Thanks for sharing info about Dlinks web page. I wish my ISP was supporting it. 

Keep us posted on how it goes.
