Hey guys, I just recently migrated to Fedora 15(but still also using ubuntu ), and already got a problem with the internet connection via wifi.
The connection goes really slow like hell, and yet very unresponsive due to the bug(some users also reported as well).
Well, I think I got the solution for that. Please follow this easy instruction.
You just need to go to the terminal and type:
sudo nano /etc/rc.local
Then you will enter the nano editor and type this following command:
iwconfig wlan0 rate 54M exit 0
* Note that you might need to install nano first by typing:
yum install nano
Just logout / reboot your computer and it should have fix everything
