Bug Description
Binary package hint: network-manager
I'm having wireless connectivity problems with my netbook. The connection alternates between being fine (short periods) and no connectivity (longer periods), resulting in upwards of 70% packet loss over a prolonged period of time.
These problems only occur with the Ubuntu Netbook Remix install. The seperate WinXP install has no wireless connectivity issues. The problem is also just with wireless, as a wired connection does not display any packetloss.
I'm using network-manager, but I've also tried wicd with no improvement. The channel being used by the router also does not seem to matter, (I've tried 1 through 11.)
The only thing that I can see that seems off in any of the settings (full output below):
IE: IEEE 802.11i/WPA2 Version 1 (from iwlist)
The network I'm using is 802.11bgn, not 802.11i. I can't seem to find this setting anywhere else though. I'm trying to use 802.11n, or g in the worst case.
Router: Dlink DIR-655
Netbook: Asus EeePC 1000HE

I can comfirm this bug on a Acer Extensa 5430-5855. Atheros Communications Inc. AR928X Wireless Network Adapter .Connection drops often. Large file transfers from bit torrent or scp can force this condition. Started out default. Network Manager wouldn't reconnect on it's own. Tried jaunty-backports no effect. Tried Wicd. still dropping connections but will reconnect on it's own more often. Also tried compile compat-wireless stable module no effect. Tried compiling bleeding edge driver but error in the source code so stopped. Tried bluetooth coexistence to no effect. Disabled bluetooth to no effect. Also it is noteworthy that the bitrate in iwconfig for wlan0 is Bit Rate=0 kb/s. I had that issue with a broadcom driver a few distros back and the results were similiar to this.
All worked fine in hardy never had an issue on the same hardware. Only good thing i can say is when connected scp speeds are 5MB/s where in hardy they were 2.5MB/s.

This is current but i have tried multiple versions including the stock firmware to rule this out.
Settings mixed mode. WPA2 but again I have tried g only, n only, and WPA . all have issues.
