View Full Version : [ubuntu] [SOLVED] Wireless not detected/working after installing Intrepid

November 3rd, 2008, 08:28 AM
With Hardy, I had to use ndiswrapper to get wireless working, but otherwise it was a fairly simple procedure. After installing Intrepid this morning, however, I can't get Ubuntu to even recognize my wireless card. I've tried enabling the wl driver in the Restricted Drivers Manager, and I've tried using ndiswrapper with the Windows driver, but neither works.

My wireless card is a Broadcom Corporation BCM4328 802.11a/b/g/n (rev 03). When I install the Windows driver using the ndisgtk GUI, it says that the hardware is present. If I run Hardware Testing from the Administration menu, the card is likewise detected. Otherwise, it's as if the card doesn't exist.

Here's the output of "iwconfig":
lo no wireless extensions.

eth0 no wireless extensions.

pan0 no wireless extensions.

... and "ifconfig":

I really need to get wireless working again, but I'm stymied. Help!

EDIT: Following the suggestions on this thread (http://ubuntuforums.org/showthread.php?t=968028) seemed to help. I can see and use my wireless card now, but it doesn't seem very reliable. I'll mark this solved, but I hope someone comes up with a better solution.
