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.

I'd say it's related to bug 698925

I have the exact same problem, see my smolt page: http://www.smolts.org/client/show/pub_eee073ef-5435-4449-8a7b-42793b31248b
