Amazon Firestick 4K Max, when bought in UK, comes with all those UK programs and has apps for many others.
Install your VPN also on that Firestick and watch it anywhere on a TV with HDMI-port.
PS: don't forget your remote and don't leave it behind in your (hotel)room.
My RT-AC68U is a converted TM-AC1900, which runs Asuswrt-Merlin 3004_384.13 from 2019.
Still running fine, currently in Repeater mode (from an RT-AX86U) for only my USB-printer upstairs.
However, I have not been able to update that router with any Asus or Merlin firmware since 2019.
