    How to install wifi driver on unbuntu?

    I just recently installed Ubuntu on my Lenovo ThinkPad E540, now I can not figure out how to install the driver for the wireless adopter. I've seen people with the exact same computer and have the wifi working, so there must be a way to install it.


    Please help. Thanks

    Some things stopped working after i installed Ubuntu on my laptop

    Not only the wifi, also the indicator lights for Cap-lock and number-lock. Are these problems solvable? My laptop is Lenovo's ThinkPad E540 if that helps.

    So the wifi worked when you were testing it in live mode before install?

    I suspect it could be a part of your wifi needs blacklisting
