Bug Description
Added description on June, 4th 2010:
This bug is still present in 10.04 Lucid Lynx. In comment #161 I've described a workaround that should be effective, at least in Lucid.
--Pjotr12345
----------------
Binary package hint: linux-ubuntu-
I'm using hardy alpha 4 (on Linux nand-laptop 2.6.24-5-generic #1 SMP Thu Jan 24 19:45:21 UTC 2008 i686 GNU/Linux ) and I was testing a PCMCIA rt2500 card :
03:00.0 Network controller [0280]: RaLink RT2500 802.11g Cardbus/mini-PCI [1814:0201] (rev 01)
with WEP encryption, near the AP :
wlan0 IEEE 802.11g ESSID:"
Bit Rate=1 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr:off Fragment thr=2346 B
Link Quality=43/100 Signal level=-54 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
The connection is working, but slowly (40 kb/s). It's due to the bit rate being set to 1Mb/s. If I manually set the rate to 54Mb/s, then I got the 900 kb/s I expect from my AP.
I have also tested with one other RT based I have, a RT73 one, and the bit rate goes automatically to 54Mb/s...

I confirm this behaviour with a MSI CB54G2 adapter (rt2500pci/cardbus)
