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.
