I loaded AU firmware in my C1200, it has been running fine since last sunday.

I disable USB, printer server, firewall and many others. The CPU load was between 10-66% and most of the time stays at 4x%. Which I think it is still pretty bad.Tonight gonna test it with huge number of connection of download.

Some forumer did mention this firmware is based on open-wrt. I hope there is a custom firmware on this.

In the meantime, I am waiting for my AL68U to replace this crap.
