Is this for a USB wifi device? If so what kind?|
Anything in iwconfig?
Anything if you type:
$> lsusb | grep '802.11'
If so, what's the make/model? I'd grep dmesg and also lsmod to see if the actual manufacturer's driver is loaded, or any driver for that matter.
If not, get one and modprobe it, see if something shows up at least in /dev (might want to ls /dev > before this way you can ls /dev > after and diff the two after you restart networking (or the whole thing).
If they don't have sources or an ARM compilation I'd probably check the docs in that library for that make and model.
Personally, I have a NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS] that has given me problems in almost every Linux distro I've used it (even AFTER installing the OEM crap).
