Installing Ubuntu on a Toshiba Satellite P15-S420 Laptop

I installed Ubuntu on my Toshiba laptop tonight. Unfortunately the DVD drive had broken, so I had to use PXE to network install from another server in my house. That went fairly smoothly, but once Ubuntu was installed the integrated Atheros wireless network card wasn’t working. To fix it I had to install some linux restricted kernel modules via:

sudo apt-get install linux-restricted-modules-2.6.17-11-generic

Except, replace 2.6.17-11-generic with the output of uname -r

Once that was installed it all started to work quite nicely.
