Sorry but since Im new to this forum I had to post the first message without links, now there is what I did:
A solution to your problem is to disable or uninstall NetworkManager and instead install Wicd instead you can download it from
http://sourceforge.net/project/showf...roup_id=194573
for complete installation guide you could check
http://wicd.net/moinmoin/Wicd%20on%20FC9
Also if you run the command iwconfig and you notice that your rate on the wireless card is set to 1M like in this output:
wlan0 IEEE 802.11bg ESSID:"xxxxx"
Mode:Managed Frequency:2.422 GHz Access Point: xx:xx:xx:xx:xx:xx
Bit Rate=1 Mb/s Tx-Power=27 dBm
Retry min limit:7 RTS thr

ff Fragment thr=2352 B
Encryption key:xxxxxxxxxxxxxxxxxxxxxx
in my case wlan0 is my network card your could be different. You can set it manually running
iwconfig wlan0 rate 54M
to set the rate to 54 Mb/s assuming you are in a 802.11g WLAN
Hope this is of some help
