(adsbygoogle = window.adsbygoogle || []).push({}); My cousin has a laptop with ubuntu and we are trying to make it wireless but we can't figure out how to we need help.

Setting up wireless is no different than under windows. You just need the card and the correct drivers for your system.
You must login or register to view this content. I suggest going here and reading up on the support page, the Linux community is a helpful one.

Can you actually access the wireless? if not you might need to install a broadcom 802.11x driver for some networking cards

Can you post the output of lspci -nvv and if possible the hardware on the system?

With that it will be much easier to help you.
