Speeds are consistently slower than service contract though notably hub > pc speed is a good chunk slower than hub > net speeds (a good 30-40%) Looking at that site I have the legacy ADSL hub which is more than 10 years old at this point.

They actually tried to send me a replacement once upon a time but the one that arrived was a lemon (wouldn’t even power up) and customer support is less than fantastic.

Would something like this work? https://www.tp-link.com/uk/home-networking/dsl-modem-router/archer-vx1800v/#specifications
From what I’m able to discern it still supports wifi 5/.ac standard which is helpful since not all pcs in the house can handle wifi .ax standard and should be a damn side better than an ISP provided router.

Nevermind despite having Modem in its name it cannot actually function as a modem according to their own tech support forum. Back to square one.
