@Jay551 you're with Virgin Media? If so then you're not the only one. Not sure exactly what it is, but since the beta 1, devices somehow crash VM SH3. I've heard people saying clearing network settings worked for a bit, I also had a few Virgin engineer visits but they had no clue (and replaced everything). I ended up buying a new router and putting the Virgin Hub into modem mode, not had an issue for almost a month. Virgin are also starting giving their new Hub out (with WiFi 6) so hopefully this one should be better.
