Please try the FC6.netdev kernels:


Do these work any better for you?

Comment 2 Brennan Ashton 2007-06-12 23:05:46 UTC
This problem is resolved in the 2.6.22-rc4 kernel. 

Comment 3 John W. Linville 2007-07-16 14:39:05 UTC
Please try the kernels here:


Do they resolve the problem as well?

Just wanted to come in here and add the traditional "me too" for the broadcom
1390 using I'm using the newer mac80211 driver just fine and
everything is working, it's just that the speeds are very very slow. 

Comment 5 scott anderson 2007-07-24 01:42:42 UTC
Wanted to add that I also tried the more recent kernel-2.6.23-0.45.rc0.git16.fc8
and still the speeds were the same. Not sure if this included any type of fix
but just thought it was worth noting. 

Mr. Linville, if you build anything else and would like me to test it please let
me know. I really would like to help solve this problem any way I possibly can,
so if you think of any other way I can help please do send an email.
