Frustration beyond anything in Windows! I have used 12.10 on HP Laptop no issues, decided to go with 12.10 on Desktop (AMD32), every thing went fine until loading USB Wireless drivers. Loaded/Unloaded NDISWRAPPER what seems like 40 times, applied and finally did a build (make, make install, modprobe) and the card came up, but won't authenticate. I'm not a guru on Ubuntu, so my technical knowledge is limited. I have tried 2 cards now and no go.

Is this why Ubuntu is not "main stream". It seems so ridiculousness I can't get this to work, especially after purchase the card recommended in the hardware list. (listed as "PNP")

iwconfig

lo        no wireless extensions.

eth0      no wireless extensions.

From ndiswrapper -l bcmn43xx32 : driver installed device (0846:9020) present – Steve Apr 22 '13 at 21:42

Ndiswrapper is totally obsolete and causes problem than solving it.

In old days, Ndiswrapper was a successful tool but as of today, when almost all hardware manufactures are providing drivers, it must be used as last resort.

From a quick search, it look like netgear devices has really some problem with ubuntu..

This is Broadcom BCM43231 chip, so please give a try to Installing Broadcom Wireless Drivers (specifically this answer)

I recommend a full reinstall of ubuntu to get rid of all changes by ndiswrapper


Another reference of the same chip and NetGear USB Getting Ubuntu to recognize a BCM43231 network card what is up with terminal

As a last resort, if you have to go with the ndiswrapper way , follow this - http://ubuntuforums.org/showthread.php?p=11199585
