1.) Google for ProtonVPN, register, download and install (absolutely no payment or credit card information is needed for the free servers from the USA, Nethlerlands and Japan
2.) Try every server from the USA, on Server 3, 4 and 8 I get at least 40 mbit, sometimes 70mbit (with a 120mbit connection), still not what I should get with my connection, but better than the 10mbit I get without VPN
