When I run a rsync to backup my home folder over the network like so:

rsync -avhz --progress --delete /home/dbdean/ [email protected]:/home/backups/david/

I seem to have problems with my quite large .VirtualBox/HardDisks/Windows XP.vdi file. Occasionally the wifi will silently fail (the transfer stops, and any other network access is broken). If I reconnect the wifi to my network before the transfer times out, it happily keeps going (and other network access is back), but I can't just leave it unattended most of the time, as I have to keep an eye on it.

I'm guessing this is probably a bug in the wireless card related to a particularly high sustained volume of network usage, but I'm not really sure where to start with diagnosing this problem so that I can provide a good bug report. Or it could be something else, I guess. Any help would be appreciated.

My network card is an Atheros Communications Inc. AR9285, as lspci -k shows:

43:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) (rev 01)
Subsystem: Hewlett-Packard Company Device 3040
Kernel driver in use: ath9k
Kernel modules: ath9k

Are you using an Atheros wifi card on Natty? If so, try upgrading your Linux kernel to 2.6.39. See my answer on Wireless on an Atheros AR9285 is slow and disconnects for more information.
