Found very similar threads but none apply to my USB dongle so... My USB dongle is recognized but it won't find any networks. Here's what I've done so far (this is on Mythbuntu):

I was able to connect at one point but then lost the connection and haven't been able to get a list of networks or any connection since... Suggestions??

Sorry for the delay... had to step out for a sec.
Not sure what happened - after about 4 days without wireless, it misteriously came back... the same way it went away, I didn't do anything other than setup some channels in mythtv and I highly doubt that it has anything to do with it... Go figure... Nontheless, here are the outputs:
dmesg | grep wlan

Sorry for highjacking this Thread.

I googled around but could get no further Information.

I have a TP-Link WN821N USB Dongle which also uses the ar9170 Chipset, it is running ok since 2.6.32 Kernel Drivers. The Dongle runs stable about several hours with WPA or WPA2. My Router is a Netgear WNR3500L wich i tested with stock and dd-wrt Rom.

Now to my Question.

Which transferrates do you get with your ar9170 driven USB Dongles?

I tested transferrates with netio and get very low transferrates.

from windows to Linux:

NETIO - Network Throughput Benchmark, Version 1.26
(C) 1997-2005 Kai Uwe Rommel

TCP connection established.
Packet size 1k bytes: 494 KByte/s Tx, 71 KByte/s Rx.
Packet size 2k bytes: 524 KByte/s Tx, 72287 Byte/s Rx.
Packet size 4k bytes: 729 KByte/s Tx, 71953 Byte/s Rx.
Packet size 8k bytes: 695 KByte/s Tx, 79 KByte/s Rx.
Packet size 16k bytes: 709 KByte/s Tx, 70 KByte/s Rx.
Packet size 32k bytes: 750 KByte/s Tx, 81 KByte/s Rx.
Done.

Did someone experienced better transferrates, and if yes, how?

P.S: Under Windows XP i get about 7-8 MB/s.
