the TPlink wired powerline adapters work well with the hub one, i use 2 pairs to run 1Gbp up to upstairs to switches in each upstairs room so everything runs wired in each room upstairs, but you could put a wireless router or booster at each end if its weakspots due to walls etc.
you simply pair them together in 2 sockets next to each other then take 2nd one to destination plug in to wall and the lan cable to a switch or wiresless booster if needs be, their mesh boxes would be perfect and flood all floors with wifi, combined with a wired feed via the powerlines
5Ghz wifii is woeful through walls with any router, (meant really for same room/floor/plasterboard walls) communications
red brick forget it mate or thick sandstone/granite etc, in those deadzones put the 2nd power adapter there and link it to whatever options you want to have good localised wifi.
if its an older well built stone house all wifis going to struggle buddy, tyhe plusnet routers a pretty decent unit with decent features, better than what most ISPS after BT supply, which is what plusnets hubone is based on if i remember correctly.
