I'd like for you to test this router in a different location just to see if these temps follow if possible. With and with out the WiFi radios on with out any LAN devices connected. Just sitting there. I'm wondering also if there could be a power problem as well. Maybe the router is getting to much DC on the adapter maybe? The router should not be hot if nothing is connected and doing anything.

These temps are a bit high, however there has only been a few people mention it here in the boards. I have both the 827 and 857 routers and the run well, warm sometimes. However I don't have WiFi congestion here and use them on a normal basis. Nothing extreme. Even sitting with radios going, usually hang around 80-90F.

Have you phone contacted D-Link support yet about this? I would and talk to someone at level 2 or higher.

I'll post back if I hear anything about this on my end.

WiFi congestion is a big issue in a large apartment building.  However, I see no label on my box that says I must live 50 miles from anyone else for this product to work properly.  I keep my apartment fairly cool also (about 45F) as I love the winter and have ridiculous A/C for the summer.  I have taken the temp gun to my RT-AC66U with that under more load than the DIR-857 could ever take an it doesn't even touch 40C, let alone 50C.  Before I bought the Asus, the D-Link was seated in the same place.  Everything in here is plugged in to APC Surge Arrest 11's that are rated for commercial use.  Again, no complaints with the Asus RT-AC66U.  My DIR-855 holds up better under full load than the DIR-857 does with light use. 

Before I took this thing up to my cottage which is in a fairly rural area, I had talked to D-Link about it, posted about it, and tried a few different internal beta firmwares that were sent directly to me from Pardeep Vahra with no real improvements.  I gave up on it for home use and took it up to my cottage where I barely use it for anything other than web browsing.  My cottage and being a few miles away from anything, this router still tops 40C easily and hits 54C under heavy loads.  Even using the PowerLink Boost N for WiFi on it with the WiFi for the DIR-857 turned off, there were times it would just stop sending traffic.  I was never offered an RMA and as stated, I moved on with a fantastic product.  Considering I have owned D-Link after D-Link all the way back to the late 90's.  I have come to the conclusion that their products just aren't up to the quality they once were.  I do hope everyone else has a much better experience with the current product line. 

Furry and Patrick, you both do great stuff here and D-Link is definitely lucky to have two excellent posters that are as thorough and knowledgeable as you both are.

Understand man. We understand the frustrations as well. Over all I think there is a problem with your particular router and a few others that have expressed there concerns about it.

Not sure if D-Link Canada would be willing to offer you an RMA if it's still in warranty. I would press them about one if it is in warranty.

I have asked D-Link USA to review this and offer any info about the temps. I'll post back if I get any info.

I would like to thank you for your patience and working with us, even on dong the Mod and testing as you have spent your own money to see if the mod would help. This has been informative, however I wish it had worked out better for you. I do believe there maybe a problem with the HW on your router and do hope that D-Link Canada can get you an RMA. Your router needs to be inspected by D-Link for this issue to see whats actually going on.

Over all, D-Link routers are built well and work well. I have expressed by concern about the heat issues to D-Link personally. The newer canister style routers are nicely built and seem to have better heat dissipation since the air flow is better designed in them. I have enjoyed the 827 and 857 routers though. I presume that this style of case will no longer be used since D-Link has moved to the canister style now. I they been keeping with the older box style in some of there rev follow ons with external antenna features. I wouldn't let this one experience completely turn you off of D-Link products though. I know you have moved on, however something else maybe in the future.

I'll post back if I hear anything. I would pursue an RMA if possible.

Good luck.

If they offer me one knowing I have taken it a part and added the heatsinks to try and help get it stable, I'd send it in, heatsinks and all.  When it comes down to my home setup, I need something that works and reliable.  I had heard a lot of good things about the Asus RT-AC66U when it launched and I got a promotional deal on it locally.  It was too good to pass up and I needed something reliable for both streaming and gaming. 

I'm actually glad you messaged me to about trying that mod though.  I enjoyed taking it a part and such to try and help out.  I don't mind that stuff at all and it has been a fun learning experience for me as well.  I have never had to take a part a router before and I do hope D-Link takes a look at these issues some are having more seriously.  I really had hoped this mod would have helped out my router and it has to a small degree.  Unfortunately, it just wasn't enough as it still runs over the temps listed in the manual with added cooling.  Most of all, I hope D-Link takes a look at all of the testing and feedback here and produces a better product for the consumer down the road.  A more powerful processor, better cooling, and a realization that consumers need more than a 2Mbit uplink are three things I think D-Link need to take back to their design teams.

Most of the newer routers have fixed the 2Mb Uplink cap...they use the new Traffic Shaping engine that the 645 came out with. Up to 10Mb Links are selectable now.

If you do get an RMA, you could take the mod out and clean it up if needed. Hehe.

I like the cylinder style routers now. Heat doesn't seem to be problem now.

Ya it's interesting to break open one of the routers and see what it looks like under the engine hood.

10Mbit uplink is a step in the right direction.  With fiber and cable speeds hitting well over 100Mbit, I still think they have a long way to go in that respect.  The best fiber connection in my area is 175Mbit down/175Mbit up.  That's a service that is a lot more than I would want to pay for but 10Mbit seems to be the bottom line for upload on any fiber service up in a major city. 

I'm not a huge fan of the look of the cylinder routers but I wouldn't not buy one based on the look.  For me, it's purely about reliability and performance.  It could come in hot pink with My Little Pony's all over it but if it was a solid product with great performance, I'd hide it under my desk.  :p

Well there had been some debate about uplink speeds. I presume with 100Mb uplink speeds, there maybe no cause for doing any Traffic Shaping at those rates. I presume there maybe some point that any data manipulation just isn't needed.

This is the new Traffic Shaping UI being used:

Even thought the canister style may not appeal to some, They are very good from what i have, I have 2 of them and I have been enjoying both. The 826L is a great follow on to the 827, 825 series routers and the 868L is the best of them all IMO. Thats just me...

Hi Furrynutz.

As I mentioned on my post for DAP-1360 firmware: http://forums.dlink.com/index.php?topic=62278.0

I modded my DIR-827, I used the 3 heat sinks and so far it has been 4 days (almost 5) that my WiFi is working as expected.

But still I'm concerned about the DIR-827, If i touch the case at the top, it stills feels very hot, but so far it has not collapsed.

I turned off the 5 GHZ band (to diminish a bit the processing for the DIR-827):

I'm thinking on getting a cooler fan base (for 10" laptops) and place it beneath, just in case.

Kind regards

Yes, I use a laptop cooler for any router I have online now days. Just better to be safe then sorry.

Why DLINK is not cooling his hardware????
indeed it's a design flaw and obviously demonstrate a lack of testing...

I will go an get a laptop cooler that fits well the DIR-827, hope my WiFi is Ok

Thanks

This case style for the amplify line was the first case change since the DIR-855/655 case style.

We can only presume that may be some ventilation considerations where not fully checked when these were designed and MFrd. Since then D-Link has taken into account of these learning experiences. The cylinder style cases work well since then. The DIR-880L has the same style case as the amplify line, just bigger, however the under case has way more ventilation holes now alone with the external antenna.
http://forums.dlink.com/index.php?topic=59563.msg237035#msg237035
I presume that if the amplify line had these holes, the heat issues may have not been as prominent.

Over all, I think there could have been a bit more testing and development in regards to head dissipation issues that the 857/827 saw. Not everyone had the same problem however seems that most of the problems are centered around not having good ventilation and releighing too much on ambient heat dissipation with out more adequate ventilation holes with out knowing the long term consequences of heat on electronic components.

I tend to agree and this has kept me away from D-Link products for quite some time now.  Although I don't think active cooling is relaly needed on these models, I do think some gtood copper heatsinks could have gone a long way.

DLink has come along way in there cooling designs. Specially in the AC router models.

Most Mfrs don't use any active cooling designs at all. Most reliegh on good heat sink design and good case ventilation. I know of only one router that has a fan in it however it's not active, only trigger when router hits a high temp.  ::) And the fan was removed in the Rev B version of the same model router.

For my personal use and peace of mind, I run a laptop cooler anyways, regardless of case style and ventilation. Just seems to help with any kind of router case and ventilation needs. This is not to say that most routers are not designed well. Most are now days and like I said, I think D-Link has learned there lesson.
