If its 5ghz, you should look into the settings and make them as 2 different signals. Keep the best one for you only. Example, good range: 5ghz, bad: 2.4ghz. (Look into guides etc)
I used to have the same issue and solved it by doing this, and no, im in the UK too.
its fine i already done it just there it actually works better cos i realise now my rooms pretty far from the router also wano arc if my fave so far i love how the animation changes to something more brushlike
