Thanks, I have taken off the ability to connect via 2.4ghz using the virgin media connect app. Last night no issues so far today seems ok although no one has been using it. Will make some changes in the settings as we have some older tech that needs to connect to the 2.4ghz band. Just a head scratcher as to what has changed recently as we have had the hub 3 for a while now with no issues at the start and now issues for a few months.
