I'm experiencing very slow connection speeds with my wireless card (chipset is
Ralink 2500 PCI).
I'm using openSUSE 11.0's stock kernel 2.6.25.5-1.1-pae on a x86 system.
iwconfig reports a speed of 1 Mb/s:

# iwconfig wlan0
wlan0     IEEE 802.11g  ESSID:"mySSID"  
          Mode:Managed  Frequency:2.427 GHz  Access Point: 00:18:39:20:C9:C0   
          Bit Rate=1 Mb/s   Tx-Power=27 dBm   
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B   
          Link Quality=49/100  Signal level=-64 dBm  
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

It seems that the connection speed is incorrectly detected.
If I set the correct speed manually I get the expected speed:

# iwconfig wlan0 rate 11M
