Hi I upgraded to virgin 4 hub and 1GB Wi-Fi and it’s actually giving slightly slower speeds than my virgin 3.0 hub with 350mb Wi-Fi I had before on download speeds (so around 300mb) I use Bt whole of home Wi-Fi discs to boost speed through house so did speed tests through them but also through the virgin router with those turned off. No difference. My equipment and upgrade to 1GB only went live yesterday. Anyone else experience the same? Found ways to improve?
