How reproducible:
Problem observed every time.
Steps to Reproduce:
Use Network manager to connect to wireless network(I tryed only wpa enabled).
Actual results:
Connection is unusable after fiew minutes.
Expected results:
Normal usable network connection.
Additional info:
The network was quit slow on Fedora 14 as weel, then the updates with kernel 2.6.35.11.83 fix it.
Workaround:
In Fedora 15 - disabling power managment on the card make the problem disappeare.
Opps forgot current kernel version:
2.6.38-0.rc6.git6.1.fc15.x86_64
Also before this Fedora 15 I try for a while Fedora Rawhide, kernel was
2.6.38-0.rc6.git.1.1(not 100% sure), but no wireless at all with that one.
