Description gene c 2010-04-01 01:11:12 UTC
Description of problem:
Wired works fine.
wifi (iwlagn) connects - and ping and hostlookup work. Start up browser with large number of saved pages - (hits network somewhat) - and network stops.

NM shows all is well.
iwconfig wlan0 looks fine
ifconfig wlan0 looks fine.
ip ro sho looks fine.

However I can no longer even ping the default route.


Version-Release number of selected component (if applicable):
kernel-2.6.32.10-90.fc12.x86_64

Booting older kernel (2.6.32.9-70) and problem goes away.

Comment: This seems to be specific to N network - as I had used same machine with G network a few hours earlier and saw no problem.

Nothing of interest in /var/log/messages or wpa_supplicant either .. as far as the machine is concerned all is well.... sort of. Fortunately older kernel works fine.

Comment 2 Andy Wang 2010-04-01 03:30:19 UTC
I'm seeing the same problem.  Nothing of interest in kernel messages or anywhere.  iwconfig wlan0 shows extremely low bit rates.

Comment 3 John W. Linville 2010-04-01 14:40:25 UTC

Can you try the -94 kernel?  Does it behave better for you?

Comment 4 gene c 2010-04-01 16:18:59 UTC
I will install and let you know (wont be able to do this for several hours but I will def test it. 

Thanks.

Comment 5 gene c 2010-04-01 23:34:34 UTC
I confirm this build (-94) fixes the problem - thank you!

Do I close the bug or you do that ?

thanks again!
