I have TP-Link WR841ND (2x2 MIMO Atheros XSPAN Router) and WN821N (2x2
MIMO Atheros XSPAN Router).
On the PC with the WN821N, lsusb reports:
Bus 002 Device 004: ID 0cf3:1002 Atheros Communications, Inc.
and lsmod reports:

Before yesterday, it was loading a module called "usb" (descriptive!!!)
and giving me 1 mbits, dropping out frequently wiht 90% signal strength.
Now, it is loading ar9120usb, which is probably correct, but still
connects at 1Mbps:
wlan6 IEEE 802.11bgn ESSID:"kismet"
Mode:Managed Frequency:2.412 GHz Access Point: 00:1D:0F:D9:DD:08
Bit Rate=1 Mb/s Tx-Power=20 dBm

Power Management:off
Link Quality=61/70 Signal level=-49 dBm Noise level=-85 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
My Intel 4965AGN notebook running Win7 connects at ~120Mbps at least
twice the distance away and pushes 32Mbps / > 4 mb/s net throughput
where as this only gets ~6Mbps / <1 mb/s.
I am just wondering. Is this an issue with the in-kernel Atheros drivers
in general (at current state) or specific to ubuntu? I am running karmic
with latest updates (2.6.31-14.48).
