I've a catatonic WRT54G v2.0 to add to the list - this one, though, was not my fault. I was online last night and it just carked it. First the router/gateway function went, then when I rebooted (unplugged then replugged) it, I saw the following symptoms:
* Blinking power light
* WLAN / Internet / Switch port lights seemed to be functioning properly
* No response to pings.
I was running the Linksys (2.6?) firmware. No history of modification or third party firmware installs, I upgraded the firmware when I bought it so it would handle my cable login, and then left it alone. One network dropout the next day, solved by telling it to disconnect then reconnect to the cable heartbeat server, after which it worked perfectly for over a month.
The Linksys knowledgebase details exactly this scenario, but the reset button doesn't seem to be working. I hold down the reset button for 30+s with power on, with power off, while powering on, but no response from pings.
So, would you people recommend trying the trick shown on Void Main's site, or would I be safer just trying for a refund? At this point I haven't done anything that voids the warranty but the wholesaler I bought the router from has a track record of being slow to replace under warranty. I guess my main question is "Are my chances of success good enough to make it worth blowing the warranty?"
I've got a ticket open with Linksys support about it, so I won't do anything until I get a response from them, at any rate.
