I'm wondering if anyone can help? Several times a day the Wifi cuts out on mine and my partners phones. We both have a Samsung Galaxy S8 plus. We have tried resetting the hub and the phones and running the online diagnostic tests through the virgin media site with no joy. Online chat has been useless as Virgin Media are saying there is no problem with the connection. Does anyone have any suggestions or answers?
There is a known issue with the Hub 3 and Samsung devices (mainly S7s) where the devices get a ! Mark on wifi signal and can't access the Internet, but are still showing as connected to the hub. Is that the kind of thing you are experiencing, or do the phones actually disconnect from the hub?
VM have confirmed that they are working on a fix (see page 40 of the thread above). Current best workaround is to create a guest wireless network and connect affected devices to that instead of the main wireless network:
Disclaimer - I don't work for Virgin Media. I'm just another VM user trying to help out. My setup: V6 TV box, Vivid 200 Optical fibre with Hub 3 in modem mode connected to a Netgear R7000 router. Telewest/VM user since 2001.
