Re: How To Tell NetworkManager There's a Wireless Interface To Manage?

Rich,

Somewhere in WICD 's configuration you should find an option called
" Always use Wired Connection if available"
Make sure it is unchecked.

The existance of a wired and a wireless interface at the same time
should not cause any problem.
Normally the wireless  always wins over the wired.

You migth check dmesg , why the wlan0 is not brought up at boot time.
Maybe the module doesn't get loaded ?
rfkill has a hard and a softblock option to verify, also.

actually the interface should be visible from ifconfig after boot, but
without an ip4 address.
This is where wicd would kick in to cope with the encryption and make
the connection and run dhcpcd.

Anyway you should not need to use an usb device, as it will maybe even
make things more compicated

Good luck
Jens
