I have a WRT54G v3.1, which suddenly is bricked. The Power LED is blinking all the time. I'm not being given any IP address - so I've tried to give my PC a static IP (different ones), and tried to use tftp. At first it worked, but the router was acting weird, so I tried again - but I can't do it now. I can't find the "Auto Upgrade Utility .exe file" anywhere on www.linksys.com? I've tried to ping (and tftp) the router using 192.168.1.1, 10.0.0.1 and 172.16.0.1 (which the router had) - no luck. I've tried to hold the reset button for 30 secs, but it seems like nothing happens. The power LED just blinks and blinks... Any ideas?
