Thank you Patrick....I'm curious now to see Eluders Mod. I believe mine are the same size as yours. I used the heat tape that came with them to attach. Definitely runs cooler to me however I need to stream some heavy HD and test again.

Thank for your info. Hope we might help Eluder out to find out why his are failing. I'm hoping it might be just that, a heat xfer issue and we need to make sure his sinks are attached correctly.

[Eluder]

I have a link to my mod in my first post about the failure in this thread. Note for the bigger chip I affixed two sinks to it since the ones I had were a tad small for it. They were however the right size for the other chipset and they were all affixed with seksui 5760 thermal tape. It's too late to do anything with this dap now though. Once it fails it fails and becomes nothing more than a paper weight.   

[FurryNutz]

So after the lan ports fail it's bricked for good?

Doe AP mode work any?

Can you post a pic of your after mod look? I found it. I wonder if the larger sink should have been attached to the top most chip. I believe that the one that gets hotter the most.

I do agree, these shouldn't have to be modified to handle heat dissipation for HD thru put content. I still wonder why yours is failing and Patrick isn't seeing this issue... 

[FurryNutz]

Eluder, D-Link has told me that they are going to review this and have a look.

If you have an RMA and or Case number for theses, Please PM me this info so I can forward it to them. The more info and history they know, will be helpful. Maybe we can help get you a working unit or at least figure out what is going on with your situation since so far, it seems to be locally to your system for now.

We look forward to your info.

Thank you.

I used J.B. Weld epoxy to mount the heatsinks - far better thermal conductivity.  If the LAN chip gets too hot too fast, the thermal tape will not transfer the heat quickly enough to the heatsink (which would remain cool until after the DAP-1533 bricked itself)...  The epoxy adhesive does not suffer this problem.  Maybe that is why mine is working better than Eluder's

[Eluder]

Furry, sent you 2 cases related to the DAP-1533 failures, both with the same issue.

I used the DAP-1513 with my WD TV live earlier this evening for some HD content, no issues so far, but it's far too early to tell since I haven't pushed any massive HD content through the pipe yet.

I'm not holding my breath with D-Link here since they haven't been very helpful when calling support, never offering to do more than just replace my failed units or dig into why it's happening etc, but hey, maybe you'll have some luck and be able to provide some actual assistance.

Patrick, I understand what you're saying that the epoxy is better, but if it's still failing with my mod, then how the heck was D-Link expecting the original pad they used to dissipate heat to actually work?

[FurryNutz]

Thank you Eluder for this info...I hope that D-Link will review your information and I've asked them if they can pull our failed units to see what the failure is and maybe find a cause. I know your in Canada however we are in the same Region so lets see if USA can help with at least something in your region. One suggestion I'll ask about, if we get some info, maybe a model swap for a 1525 or something different. Depending upon what they find and if any other information is needed, I hope they can find the cause or let see if we can come up with a alternate solution. No guarantees however lets see how it goes. Test your 1513 out and I'll put my 1533 on tomorrow and do some streaming with HD and take temps with mine. I'll forward my results to D-Link as well. I've also asked them to look at the 857/827 routers as well as we seem to be seeing users posting about heat issues as well. 

Please be patient.

Thank you.

Thanks Furry, the problem with support is that when I call, it goes to India, not sure if it's the same for US support.  No offense to the folks in India, but they're not trained to handle anything special and simply give canned responses and open an RMA for you.  That's all they'll do, and that sadly is not enough for my situation, which is why I gave up on the DAP-1533.  Funny enough, I originally bought the DAP-1525 and DAP-1533, gave the 1525 to my bro in law, and he's had no problems with it.  Maybe I should have kept the 1525 and life would have been different, oh well.

BTW, I have a DIR-857 and haven't seen any major issues with it, have to reboot once in a blue moon maybe, but it's been fairly stable, and performance from it is pretty good.

Anyway, I'm around if you guys need more info from me or anything.

Thanks for the help.

[FurryNutz]

Understand man. I'll pass this along and hope that we can help get you some support from our side. I'll keep you posted. Thank for hanging in there.

Just FYI, I did some testing with my 1533 and 857 today. I attempted to stream HD content from at least 2 devices and SD content from on other. I saw 2 failures in 2 of the 3 devices not getting an IP address. I presumed there was a loss or connection issue on the DAP. The 3rd device maintained as it kept streaming. Power cycling the DAP resolved my connection issue on the 2 devices and then continued testing. LAN ports were or seemed functional after the power cycle as I got IPs on the devices afterwards.

I had a DISH Hopper streaming a HD movie from Blockbuster, Boxee Box streaming raw BD file from my DNS and my Mac Book was streaming Netflix, then switch to a MP4 and raw DVD files on the DNS. I moved the Hopper to a DIR-685 streaming raw DVD. After that, DAP seemed to maintain connections and didn't fail.

Heat was kind of warm, ready 103F on heat sink and 104 at board level right next to ship and xformer block.

I'm curious if streaming too many HD devices is a cause of failure when using default composite heat sink or mod.
I also notice that the WiFi connection speed was only 270Mb on the 857 so I presume this played a roll as well as I think I should be seeing 450Mb. Distance was 15-18feet.

Anyways, I've passed my test results to D-Link in hope this will help with information.

[FurryNutz]

And for curiosity, I bought a DIR-835 from fleabay on the cheap, as it's a close twin to the DAP-1533.

I removed the cover and of course the same composite heat sink is there. I removed the heat sink and looked at the bottom of it and noticed that not the entire surface of the chip was imprinted on the sticky part, rather two faint lines so I presume that heat xfer from the IC chip would probably have the same problem as the 1533. 

I went a head and attached a new metal heat sink and will run some tests on how warm it gets.

I took mod pics for the record:

[FurryNutz]

So just FYI, I opened up my DIR-835 after going online with it yesterday. I ran some basic test and nothing streaming video or testing wireless. I looking at the temp of the one chip that I applied the heat sink mod too. After connecting the rest of my wired LAN devices after the router was up and running with my 24pt Gb switch, I took a temp and I got 125-130F on metal heat sink. I took a temp of the one little chip to the left of the modded chip and saw 110F. I thought, Hmm, lets put a sink on it as that seemed a bit high. I believe the the reason for the high temp on these chips was due to all the activity of connecting all at once, the rest of the wired devices and the router and getting all the IPs handed out and everything coming online. I checked today and the temps were about 95-100F on the main hot chip. Everything is running ok though. This is a new router with the mod so I presume and hope that this will last longer. I presume that just using the default Mfr heat sinks just may not be enough and the other chip to the left of the hot running chip probably needs to be modded for a heat sink as well to be safe.

Just wanted to add that I've had zero issues with my DAP-1513 in the same environment that I had my DAP-1533 now for nearly two months.  So it's pretty evident that there was a major design flaw in the DAP-1533 which caused it to fail so many times for me.  Oh well, now I know to avoid D-Link products with my next network build...

[FurryNutz]

Agree that there is a bad flaw with the heat dissipation and heat sink on the 1533, however not all D-Link products have this problem.

[Eluder]

That's absolutely true, but after sales service is often the most important thing, and D Link should have made an effort with me to rectify the problem considering how many times I had to RMA the DAP-1533, but they didn't, so they've lost me as a customer.
