Turn Hub off, unplug from the mains for 5 minutes and then start it up and see if it connects by cable and if it does check the wifi ? If that still doesnt work I would call it in as a faulty Hub. It is difficult to know what fault on the network could be affecting wifi only?
Any forum experts out there got any suggestions on what that could be?
Could always try a Hub reset as well -
Push in the pin on the back/side/bottom of the Hub with the end of a paperclip until you feel it at the “stop point” and hold for a "timed" 60 seconds do NOT restart the Hub after that - just let it reconnect. Your passwords/passphrase for both Hub and Wifi will revert to those printed on the Hub sticker on its base/side.
