grishnakhMake sure that your PSU is not dead before doing anything.
You can try restore factory defaults: (I never try it

)

2. When the blue LED starts flashing, press the SW2 button
3. Stop pressing the SW2 when the blue LED starts flashing quickly
At this time the router is in failsafe mode.
4. Telnet 192.168.0.100. It will take you to the root prompt.
5. Enter "firstboot" at the prompt to reset the router to defaults
6. Restart
If router is dead you can replace it with tplink 703n or connect avalon to computer via USB.
Thanks. I did the reset and got it back working after several failed attempts. Is it a normal symptom of OCing too much that the tplink stops responding? I'm trying to figure out what caused the problem, and how to prevent it.
