I have the Virgin WiFi boosters set up in my bungalow, and they work quite well apart from one problem. My son has an iPhone and his bedroom is a flat spot for the V3 hub, hence why I got the boosters, however, as soon as the phone is out of range of the hub and the booster kicks in the phone searches for a connection, finds (presumably) the booster but has no internet connection meaning he's using mobile data. I have around a dozen connected devices around the bungalow and it's only the iPhone that has this problem. I've tried some of the fixes on here. Before I go down the route of separating the 2.4 GHz and 5GHz networks and connecting the iPhone just to one for better stability has anyone got any other suggestions please?
