I am currently unable to find any wifi connections in Ubuntu. It works fine on Windows 10, however. Ive scoured the internet, but all of the posts are extremely old and i appear to be the only user with this problem. Im on the newest released version, 6.30.223.248 . Also, assume i have very little experience, because i have no idea what im doing.

I entered sudo lshw -C network

I just answered the same question.

Dont worry just enter your terminal and enter : sudo apt-get install firmware-b43-installer

It should work again :)

Tell me if it doesn't
