Dual Boot - wireless hardware not accessible

[Wade Smart]

My nephew has a Lenovo 80K9 with a
Broadcom 4352 wireless adapter.
He is dual booting W10 and Ubuntu 18.04.
He started with Mint, then something else
and now Ubuntu. He cant get the wireless
to show up at all. In each OS there is
only ethernet.

Ive not dual booted so Im not sure this is
something normal or what. Though looking
in the mint forums a lot seem to have problems
with this adapter - which has been around a long
time.

We did go through and install broadcom
drivers but it didnt seem to work.
