Thanks for the tip. I noticed this extra network when I first became a Virgin customer (4+ years ago) and naively assumed it was something to do with the TV box. The online form seems to work now; from opting out on our online account to the extra network being turned off took about 2 minutes (we noticed the router wifi being reset as devices were momentarily booted off - and confirmed using the "Wifi Analyser" app on my phone which I think is the same as what you have used above). Should help reduce the local wifi congestion a little. [For info we have a Hub 3 (Arris rubbish) - and the MAC of the now dead Virgin Media network looked nothing like that of our router.]
