Issue: iwlist scanning sees the network; dhclient can't connect

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 
Hello,
 
I have a problem with the broadcom wireless card (BCM4306 using b43).
I'm can list the wireless ESSIDs with "iwlist scanning" command, but I'm
can't connect in the LAN. My dhclient or dhcpcd can't receive an IP.
When I set a static IP, I can't ping the gateway.
 
Follows the output of the interesting commands:
