everytime i plug my power hub in, the front led flashed blue for a couple of seconds and then instantly changes to flashing red, all the cables are plugged in correctly and it’s past midnight on my activation date. does anybody know what’s wrong or how to fix it? we’re in a new build and are with openreach and i’ve been told that the fibres already been run through the house. i’ve never had fibre wifi so i don’t know if/what im doing wrong or if there’s something wrong with the hub. please help me
