Last week I purchased the D-link DIR-825, flashed DD-WRT to it without issues and used it as a repeater. About 3 days later it decided not to work (literally overnight, turned pc off and 12 hours came back and I had no access). After fiddling with it I realised that all the lan ports will not work, the wireless works fine, except when I try to put it into repeater mode.
Things I have tried:
- TFTP (unavailable due to no LAN support)
- Reflashing dd-wrt
I have been searching for similar posts to this without success, a few mention the LAN ports working for a couple seconds on startup (pingable). My device never connects to LAN, not for a second.
After every method tried to recover it I decided to break DD-WRT using erase linux command in telnet, wich did exactly that. Broke DD-WRT, but the ports still do not work.
After all that I have come to comclusion that it is most likely a hardware failure, due to the sudden failure, the constant results and the results after breaking the firmware.
Another option I thought was to delete all software on it (possibily how it is now), fully brick it, and claim it under warranty, similar story to what I successfully did to my bricked phone (another reason I am hesitant for J-tag as that will automatically void warranty)
At the moment when it is turned on, both the Power and LAN 1 LED's are lit up, hangs on that for a few seconds then the power LED will flash while the LAN 1 LED is constantly lit up.
My options seem very limited, and feel that the router will end up being put into the bin, but if anyone has any further information It would be great.
if the port are dead even in recovery mode the unit is damaged. _________________ Forum Guidelines...How to get help

I'm NOT rude, just offer pure facts!

if the port are dead even in recovery mode the unit is damaged.
Ok, what are the chances of getting it covered under warranty? knowing that you now can't currently access it at all (through LAN or wireless). Technically its voided since I flashed it, but I did the same sorta thing with my phone and got it covered by warranty
Everything was working perfectly for several days, but one morning I came to use the computer and found none of the LAN ports were working any longer. After a 30/30/30 reset I was able to log onto the router wirelessly, and tried to flash the original DLINK firmware. I received a success message but after rebooting the router it still had the DD-WRT firmware. I also tried to flash with an earlier build of DD-WRT, and again received a success message, but the firmware remained unchanged at the latest version.
Is there any way to recover the router once it's in this condition? Any ideas as to why the flash isn't working, even though I'm getting a success message each time?
Perhaps I'm missing something here, but it seems that neither cg2101 nor tranehigh has the same problem as Crossword (OP). If you can flash the f/w with a LAN port, then your LAN is not dead. (Unless you're trying to flash f/w via wifi using the upgrade function???)
However, I believe I have the exactly the same problem. Wifi works fine, but all 4 LAN ports and the WAN port are completely dead. I've set it back to factory defaults, but that didn't help. I don't even get a link LED on the laptop any more. (It's possible they respond for 1s, but I have not observed this.) This looks very much like a h/w failure to me.
One other thing that I noticed. I had finished playing around with it, and had just start to really use it. It worked fine for a couple of days, then I came home from work one day, and noticed the LAN ports were not responding. I went to see why, and I noticed the unit was very warm - much warmer than it should have been, IMHO especially since it's a "Green" router.
I got a really good deal on these routers, so I actually bought two. The second one is working fine.
Has anyone else seen the all the wired ports just die?
This happened to me last week on my DIR-835 (rev A1) which likely has the exact same chip controlling the LAN ports.
All LAN ports and the WAN port were dead, I couldn't even get a link light on the device(s) at the other end. Wireless worked fine and I was able to access the router, but I couldn't flash it back to factory through the wireless interface. Tried 30/30/30 and got the recovery mode prompt via wireless (LAN ports still dead) but also could not flash the factory firmware.
Now that I think about it I probably could have successfully flashed the factory firmware using the command line (I only tried through the GUI, it does not work via wireless) But who cares, I returned it. If they deny me service on an obvious hardware problem because I flashed DD-WRT, it would be the last product I ever buy from Dlink.

Like the others, I believe my hardware is faulty, and I'd like to have it replaced under warranty. I assume that installing non-vendor firmware voided the warranty, and so D-Link has no obligation to replace such products.
Q: How best to proceed? Is it possible to completely wipe all evidence that it ever had dd-wrt on it - given the limitations (and without opening it, obviously)?
On the other hand, it only cost $40... It will cost me more than that to navigate the return process.
What I'm much more concerned about is - is there an inherent design flaw with these units? Will my other DIR-825 C1 also fail before long? The natives (at home) will become very restless if this happens when I'm not around to fix it...
You can download the latest firmware and flash it directly onto the unit. With the LAN/WAN dead you'll need to do it via wifi, but you can't use the GUI over wifi. So you need to login via SSH, download the factory firmware to /tmp, and follow the instructions in the Wiki for flashing via command line. I probably should have done this with mine but I didn't think of it immediately after trying to flash it failed. I just wanted to box it up and send it back.
Personally I don't think they'll bother to check it. When they receive it, they'll plug it into a switch they have on their desktop, see no link light on the switch port, try the other LAN ports and WAN port, and find the same thing. Exactly as the notes from your support call will have indicated.
It is unlikely they'll go further than that in troubleshooting. These techs probably have a quota for how many items they have to process per hour, and probably don't waste time looking for a way to void warranty service on such an inexpensive item.
I never thought to enable SSH or Telnet from default so looks like I can't get access. I thought Telnet was enabled by default but turns out I was wrong.
slice1900 did you warranty straight back to D-Link or through retailer?
Huh? You can enable SSH/telnet through the GUI at any time. If you have no LAN/WAN you still have wireless access to the GUI to be able to do this.
I sent mine to Dlink, it had purchased a few months ago. I received an email yesterday that they'd shipped me a replacement DI-835 and provided the tracking number, so either they didn't notice DD-WRT had been flashed on it, or didn't care.
Hmmm, my symptoms are slightly different then. I can connect wirelessly (user id and password work correctly as per what I set, not defaults) but the GUI does not load. DHCP allocation of IP addresses even works and PC is automatically allocated an IP address (over WiFi) but GUI definitely will not load.
No problem, will try and return to D-Link and see how I go.
