Title:
  slow speed (1MB/S) on ubuntu karmic 9.10 64-bit using smcwusb-g
  (ezconnect)

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: linux-backports-modules-wireless-karmic-generic

  hello

  here is iwconfig, wlan1 is the problematic one, wlan2 side-by-side.

  wlan2     IEEE 802.11bg  ESSID:"Acutron"  
            Mode:Managed  Frequency:2.437 GHz  Access Point: 00:13:F7:E7:51:61   
            Bit Rate=54 Mb/s   Tx-Power=27 dBm   
            Retry  long limit:7   RTS thr:off   Fragment thr:off
            Power Management:off
            Link Quality=70/70  Signal level=-17 dBm  
            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
            Tx excessive retries:0  Invalid misc:0   Missed beacon:0

  wmaster0  no wireless extensions.

  wlan1     IEEE 802.11bg  ESSID:"Acutron"  
            Mode:Managed  Frequency:2.437 GHz  Access Point: 00:13:F7:E7:51:61   
            Bit Rate=1 Mb/s   Tx-Power=27 dBm   
            Retry  long limit:7   RTS thr:off   Fragment thr:off
            Power Management:off
            Link Quality=60/100  Signal level=60/100  
            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
            Tx excessive retries:0  Invalid misc:0   Missed beacon:0

  wlan1 displays low signal level and slow speed, wlan2 is internal and
  was performing much worse and in a buggy fashion before the upgrade
  from 9.04 to 9.10. That was the reason I had the smc unit. Now the
  problem has reversed.
