Comment 5 for bug 737067

This bug also affects Asus EeePc 1201T.

I have the same issue with wireless connection. After some huge amount of traffic at high speed it just drops. Networkmanager, ifconfig and iwconfig show that everything is ok, but the network is broken. No pings, etc. If I disable and reenable wireless it will reconnect and everything will work until another huge amount of traffic (usually torrents). When connection drops there is no trace of it in syslog/dmesg, so I can't provide any logs.

The problem appeared after a fresh-reinstall to natty amd64 from maverick i386. On maverick i386 wireless worked well. So it is a regression.

Later I will test the issue on my wired connection and also using the i386 livecd.
