ralink (rt73usb) wireless flaky connection on Fedora 11

I installed Fedora 11 on my HP Pavilion A6700Y this weekend. Other than grabbing the nvidia drivers from rpmfusion.org, the installation went virtually flawless.

Only one issue appeared, and it had to do with the wireless card on the system. Fedora recognizes the card as "Ralink 802.11 bg WLAN" and even though NetworkManager would connect me correctly to my wireless router, within 2 or 3 minutes, surfing the web started becoming slower and slower. It got to a point where I couldn't login to Gmail nor Facebook anymore.

After, trying the regular troubleshooting (reset router, turn off encryption, IPV6, etc), and doing some researching I found out about this bug on Fedora 10 (that seems to be on 11 as well).

Somehow the device gets set up to a 1 Mb/s bit rate, and causes the entire network part of the system to 'crap' its pants. By manually setting my bit rate back to 54M (as the bug suggested), I am back up and running and Fedora 11 is running like a champ on this HP desktop.

Here's how to set it:

iwconfig wlan0 rate 54M

I've been googling for the same problem for hours, thankfully I found your hint on how to solve it. I have a HP Pavilion desktop with a Ralink network chip and have had the same problem after installing Fedora 11 a few days ago.

thanks! all seems good now _o/
