I can't seem to find how/where to get the WiFi boosters.
Boosters have been discontinued and replaced with WiFi pods. these are currently out of stock - other posters here have been told that they are expected back in at the end of the month.
the only way to order them is by calling customer services.
they are free if you are on ultimate oomph or gig packages, otherwise they cost £5 per month. If you have to pay for them you’re better off buying your own kit imho.
