While still trying to get the new version of busybox on it I brought my unit to a status where it doesn't boot anymore. No ping no reset nothing.

But I didn't give up so when everything fails:

1. Give you a static IP like 192.168.1.50
2. Unplug the router for about 10-20 seconds (power cord)
3. Hold the orange EZSetup-button while plugging power on
4. Now the blue ready LED will shine
5. Use Firmware-Restore tool to upload a working firmware
6. Press Reset for about 10 seconds

puhhhh
