wow beyond wow .... what was wrong?

[Imabus]

should i reboot now or do i need to do anything to make the fix permanent?

also, do you know anything about bluetooth or should i start a new thread?

Thanks a hundred times again!

You should start a new thread for your bluetooth.

I think you're all set but if, after reboot, it isn't working, post back.

[Imabus]

new thread started for bluetooth....

i rebooted and wifi was off again, but running the two lines of code you first instructed bring it back so not to bad

[praseodym]

This means, you just need to force the driver being loaded at boot-up:

echo b43 | sudo tee -a /etc/modules

[Imabus]

That's great, thanks! I'll try it when I get home and report back.

[Imabus]

That worked beautifully! Wifi is on even when I reboot now thanks all for your help! I'll mark this solved now

[amrdarwish1975]

Please hook up the ethernet and do:

sudo apt-get install linux-firmware-nonfree

Reboot and give us your report.

It works perfectly for me right after above step .. many thanks

[amrdarwish1975]

wifi is fine just after this step .. many thanks
