It seems no wl apter was drived.

[antoineco]

wl is a module, not a device.

• lsmod shows that the module is loaded.
• lspcishows a broacom BCM433 adapter

What's the issue exactly?

[arun-gurung]

wl.ko is the driver and the hardware is the device.

lsmod shows the wl driver lspci shows the Broadcom Limited BCM4331 device

Try now with "ifconfig" and see if you have any active network interface listed.
