Unknown bit-rate information for thw wifi card under FC13

[Gabrial]

Hi all,

I am working a wireless networking project under FC13, I have Intel Pro 3945 wifif card. I have run the following command:

iwlist wlan0 rate

it always give me the output:
wlan0 unknown bit-rate information.

I have tried t set the bit rate of the card using iwconfig as follows:
iwconfig wlan0 rate 11

and then return to iwlist again but I got the same output. The problem is that I am using Click modular router to build a WLAN but no connectivity exist between the AP and clients, I have douts that this is related o bit rat info.

Any help???????

Regards,

Gaby
