I've just upgraded to lubuntu 12.04 and having problems getting the wireless working could anybody help.

Possibly, if you can show us what you've tried, what happens when you try it

I'm not quite sure where to start

A good first step is to identify your wireless hardware with the terminal command lspci. Here's an example from my laptop:

Give it a try on your computer, and copy & paste the results back here.

Can you connect on wired ethernet?

heres the reslts

Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01)

any help please

Broadcom wireless requires that you install a "nonfree" firmware.

Here are complete instructions for Broadcom in Lubuntu:

https://help.ubuntu.com/community/Wi...Driver/bcm43xx

For BCM4313 you should follow the instructions for the STA driver.

snowpine I'm trying everything but nothing seems to work, heres what I done all ready any help would be greatly appreaciated thanks

You need to tell us specifically what you've done, copy & paste the terminal commands and their output.

Don't try "everything!" Only try the specific steps for your specific card in the specific order given in the instructions.

Connect to the internet using a wired ethernet cable and:

snowpine I think I've tried everything here are notes I've taken.

ndiswrapper dkms

ndiswrapper source

ndiswrapper utils 1.9

This is good; you have kernel module wl in use, which is the Broadcom STA driver. That's Step 1.

Have you tried Step 2 yet?

Here you can activate the driver for use. A restart may be required. If that doesn't work then proceed to Step 3.

What are you using for your networking panel app? Network Manager? WICD?

Also the instructions do not say to use ndiswrapper. Maybe that is the problem, try unloading the ndiswrapper module(s) to prevent conflicts with the Broadcom STA driver (wl)?

installed and activated

Nothing shows up in the system tools -- windows wireless driver, nothing shows up in the
installed box.

I personally use Network Manager, here are the commands if you want to give it a try:

It should appear as a little icon on your toolbar; you can click it to configure your network.
