I have tried every solution given on the forums and the original "Wireless Card Driver for Dell Mini 1012 using Ubuntu 12.04?" question here in Ask Ubuntu and I am still not able to get my wireless card working on my mini 1210 with 12.04, everything else is working fine but the wireless card. Is there another solution other than:

sudo apt-get install b43-fwcutter


sudo apt-get install b43-fwcutter firmware-b43-installer

I know this sounds strange but I had a similar problem.

The cure was changing the broadcast channel on wireless router to a lower number, like channel 1 or channel 2.

Then found my wireless on laptop connected perfectly and stays connected for as long as I wish.

This is easy to do and takes very little time. I hope it works for you.

While changing the broadcast channel can often help, in this situation, the problem is that the Ubuntu system does not have a driver working to use the wireless card in the first place. If you can't connect to your wireless card, then you can't use your wireless card to connect to a wifi network on any channel. – Eliah Kagan Jul 20 '12 at 8:22
