I’ve been asked to post on here by the Virgin Media support team on Twitter. 12 months ago I upgraded to 350mb broadband and paid for the privilege. I had an engineer visit the home to balance the WiFi signal in the house too. Since then the WiFi speed became worse and more frustratingly, intermittent. The range on the hub has also reduced so the back of the house/kitchen gets very poor speed. No physical changes have been made around the hub in that time. I call 150 1-2 times per week to diagnose the issue, I just get a reboot request... rinse and repeat.
