If you have a static IP at home (depends on the provider and/or type of subscription) you can buy a router that has an inbuilt VPN server (there`s a list of VPN server enabled routers from TP-Link here: https://www.tp-link.com/us/home-networking/wifi-router/?filterby=AND%7C6111).

Setup the server, for me OpenVPN works the best, never had a failure.
