I’m with EE on a BT Homehub. Weird.
Soon as Patrik connected in and ran the software it kept pulling all the files from the server bar one. It kept blocking one file. Minute he suggested switching to the phone as a 5G hotspot (also EE) ran straight away. Funny thing is I had already tried this method the only part I hadn’t done was a factory reset from the remote. Anyways I’m delighted it’s working and it’s been on its first flight with the FCC patch!
