Get EasyTether for your phone ($10) and you can USB tether to any PC that has the companion app installed (free).
Even a Raspberry Pi works. I have a Pi configured to broadcast as a WiFi AP, so I just plug in my phone via USB and I have instant WiFi for all of my devices. Takes a fair amount of configuration to do that, but there are tutorials online. Much easier just plugging your phone into a laptop for internet on just that laptop.
Or maybe a laptop can act as a WiFi AP, too. I do know Windows can share internet out a free Ethernet port very easily.
I use a VPN so my wireless provider doesn't see Windows update or Stream downloads, etc.
