Broadcom 4306 rev 3 not working in ubuntu 10.04

[peperomia]

I'm having a bit of trouble getting the wireless to work on a Dell Inspiron 9200. Following the instructions here didn't help, though I didn't get any errors along the way. Scanning for networks produced 'No scan results,' though. I'm using Ubuntu 10.04.1.

Since there's no driver info here under configuration, I'm guessing it's a driver issue, but I don't know how to fix it. System -> Administration -> Hardware Drivers says the Broadcom B43 wireless driver is activated and currently in use.

iwlist wlan0 scan

sudo /etc/init.d/networking restart

Really everything looks pretty normal ( I admit I didn't look too closely after finding this)

iwconfig wlan0

Ad hoc is between computers, not to an A/P.

You might want to try



sudo ifconfig wlan0 down
sudo iwconfig wlan0 mode managed
sudo ifconfig wlan0 up


Which hopefully will make your connection work. This is in the terminal and the sudo will require your password, which will not be echoed (not even stars) just press enter when done.

bkratz is correct... somehow you got your wlan in ad-hoc mode.

[peperomia]

I'm not sure how the mode got changed to Ad-Hoc, but changing it back to managed does not fix the problem.

[bkratz]

How about trying

sudo modprobe b43
sudo iwlist scan

and
sudo lshw -C network

again, and copy/paste

also
rfkill list

This one may or may not have an output, if not
then

sudo apt-get install rfkill

again try again

[peperomia]

I didn't get any errors or warnings from modprobe. The rest of what you've asked for is below. There are no changes in lshw output from the initial post and rfkill reports no blocks.

sudo iwlist scan
wlan0 No scan results

I wasn't able to get my wireless working with the Linux driver. However, I was able to get my wireless working using another approach. I grabbed the windows driver from sidulus.textdrive.com and followed this guide for using Ndiswrapper with a Broadcom 4306. Hope this helps someone else!
