Welcome to the forums. ;)

 

What kind of wireless card have you? Dell (rebranded Broadcom) or Intel?

If you have the intel card it should be recognised fine, if you have the Dell wireless card this link may be of use to you.

Yeah it is the Dell that I have. Thanks for the post. I did do a search but obviously missed that post, or was too specific.

 

Will try it out tonight and see what occurs. Thanks again. 

I managed to follow the steps of that tutorial last night. Unfortunately when I turned the wireless off prior to doing the driver work I appear to have flicked the switch off the computer and therefore am unable to turn wireless back on to test if the drivers work. I was fuming.

I thought I would post the solution that finally worked for me. You will need a wired connection plug it in.

 

run in terminal:

lspci

 

My output ended with this: Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

 

Go to System >  Administration > Software Sources

Make sure you have selected the Ubuntu CD and alternative sources.

Go to System > Administration > Synaptic Package Manager

select and apply the following packages :

ndisgtk

ndiswrapper-common

ndiswrapper-utils-1.9

 

run in terminal:

mkdir wirelessdriver

cd wirelessdriver

 

Read instructions from step 2 from this link. ONLY identify, download and unzip drivers:

broadcom wireless driver

 

Go to System > Administration > Windows Wireless Drivers (this was installed when you selected ndisgtk)

Select Install New Driver

Locate the wirelessdriver folder you created and select the .inf file.

Select Install

If you have downloaded the correct driver the window will display "Hardware present: yes"

 

Your wireless should now be working. Check by:

 

run in terminal:

sudo lshw -C network

 

Your network devices will be displayed, if the wireless device has UNCLAIMED next to it, it hasn't work (make sure you identified the correct driver from external link), if not it's all good.

 

Click your network icon in the top right and you should be able to see wireless networks to connect to. If your network has securitry and you can't connect initially, disable it and the work from there.
