Re: ASUS DSL-AX82U AX5400
I would be asking myself why I need the wireless speed that these devices can achieve. Do you need it to move data around your personal network or are you upgrading to 1Gbps FTTP? Obviously you don't need these speeds with Plusnet's FTTC service.
Personally I would spend this sort of money on a mesh router setup so that I had good WiFi connectivity throughout my property rather than put all my eggs in one basket with a single router.
