Comment 3 for bug 276050

I can confirm this problem (wl-167g usb-adapter which uses rt2500usb -> rt2500 driver) on ubuntu 9.04

iwconfig
 returns : wlan0 Bit Rate=1 Mb/s Tx-Power=20 dBm

where iwlist wlan0 bitrate
 returns
          wlan0 unknown bit-rate information.

          Current Bit Rate=54 Mb/s

iwconfig <-> iwlist ????

Network is unstable and is incredibly slow (takes sometimes about 10 seconds before a ping to my router is returned)

I thought that sudo iwconfig wlan0 rate 54M hepled, but after rebooting and issuing this command again, the network
was unstable and slow again (The network was stable with ubuntu's (7.10 .. 8.10)
