Comment 14 for bug 227033

I have exact the same symptoms using the same wireless card: Netgear WG311v3 with ndiswrapper.

I experienced no problems at all on feisty and hardy using wired network. After moving my PC to another room, which forced me to buy and use a wireless card, this bug started to occur randomly once or twice a day. All the symptoms described by Alan are exactly the same on my machine (terminal, nautilus etc. cannot be started until I restart networking via Network Manager, then they catch up, error messages are the same etc.)

I also noticed, that having a samba share(s) mounted causes this strange "deadlock" to occur more often. I can see additional error messages in the output if dmesg | tail then:
[ 715.772180] CIFS VFS: Error 0xffffff90 on cifs_get_inode_info in lookup of \.Trash-1000
[ 725.749495] CIFS VFS: Error 0xffffff90 on cifs_get_inode_info in lookup of \.Trash-1000
[ 735.725806] CIFS VFS: Error 0xffffff90 on cifs_get_inode_info in lookup of \.Trash-1000
and so on...

But without samba shares mounted it happens as well, with only these error messages:
[ 1910.717822] ndiswrapper (set_scan:1212): scanning failed (C0000001)
[ 1910.967641] ndiswrapper (set_essid:59): setting essid failed (C0000001)
[ 1910.967650] ndiswrapper (set_infra_mode:149): getting operating mode to failed (C0000001)

On my laptop, which uses another wireless card with linux native driver I don't have any problems with networking.
