Description Benjamin Kreuter 2008-05-04 03:36:42 UTC

Description of problem:
The b43 driver fails to work properly with a BCM4311 wireless card in a Dell 
D620 laptop.


Version-Release number of selected component (if applicable):
kernel-2.6.24.5-85


How reproducible:
Always

Steps to Reproduce:
1. Load b43 module
2. Connect to wireless network with NetworkManager
3. Ping default gateway (or other well known device)
  
Actual results:
No network traffic.

Expected results:
Should transmit and receive packets

Additional info:
ifconfig reports packets being transmitted and received, but there is no 
actual connectivity.

Please attach the output of 'lspci -n' the contents 
of "/sys/bus/ssb/devices/ssb0:0/uevent".

Unless this is a new device, the 4311 has been well supported for some time.  
Are you sure that you don't simply have the rfkill switch enabled?  If this 
was an unknown devices then I don't think ifconfig would show a device at all.

The rfkill switch is definitely not enabled.  The b43 driver only recently 
began working correctly, starting with the 2.6.24 kernel, and this break 
appears to be a regression of some sort.  In previous 2.6.24 kernels, the card 
worked, although occasionally all network traffic would stop and the b43 
module would have to be unloaded and loaded to get things working again.  The 
card does work correctly with ndiswrapper, but I would rather use free 
drivers.

Are you still experiencing this issue with recent kernels?

Closed due to lack of response...
