I have a linksys wag354g that recently stopped working(it just stopped working. Woke up one day, noticed i had no internet connection and found out that the router wouldn't work). Now when i turn it on( that is connect the power adapter) the power led turns red and stays like that. I tried to send a new firmware using tftp but there is no response from the router(even ping wont work). Following the pinout on the wiki i soldered some headers for the serial port and tried to connect to it but i get nothing(and even when i tried to connect a speaker i got nothing which worries me). I also tried to jtag to the router but neither urjtag or hairydairymaid will detect the chip(cable works, i have tested it on an old pda...). Is there anything i can try or should i just throw it away? Thanks in advance...

I don't know about a Linksys WAG354G device. However, on a Linksys PAP2 device, a red color on power LED usually associates with a bad AC/DC adapter. See if replacing the AC/DC adapter will fix this issue.

thanks for the quick reply! i think i have another one so i will report back with any results in about 2 hours....

turns out the adapter is fine......could it be a faulty capacitor or something like that?

I've a WAG354G that has the exact same symptoms.

AC/DC is adaptor is fine, I've resoldered new capacitors on the board, and the 30/30/30 reset doesn't work.

Is JTAG possible? I'm quite confused on which JTAG program I should use or what should I even do after I get JTAG working. Anyone has any ideas on how I should proceed?
