thanks for providing feedback on this issue. Please keep in mind that using OpenWRT-trunk is not that easy for node operators of freifunk networks. I hope Rouge is able to do so - at least we will provide help in our Freifunk-Community (kbu).

I'd really like to discuss this issue at the upcoming Wireless Community Weekend in Berlin - will I meet you there?
At the moment we really do suffer from excessive driver-woos - causing the need to reboot nodes:
~ 1450 incidents have been reported within one month (http://register.kbu.freifunk.net/watchdog_bites). Some nodes are almost DoS'ed by certain - yet undiscovered - clients.

Thanks,
