Hi,

i have installed my wlan card (rtl8191se).
I have no problem with that and it works.

But my Bitrate is very slow.
So I tested thinks like that:

Code:
malte@leppi:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wlan0     802.11bg  ESSID:"Marmelade"  Nickname:"rtl8191SEVA2"
          Mode:Managed  Frequency=2.417 GHz  Access Point: 00:25:9C:27:A4:BB   
          Bit Rate=36 Mb/s   
          Retry:on   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=71/100  Signal level=-67 dBm  Noise level=-105 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

malte@leppi:~$ sudo iwconfig wlan0 rate 54MB
malte@leppi:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.
