Well i am still in the same situation speed varies between none and dropping off line to 105 mb , i have started another thread regarding it maybe being a Hub 3 router issue, during that i put an app on my phone to analyse what was going on, this told me that all the people around me on virgin, quite a few, are all on channel 44, obviously an issue with us all being on at the same time now, i followed the VM tutorial re switching box off for a while, when it should automatically find a clear channel, mine hasn't done that, i can't change it manually as it won't accept the settings password on the label, i am very frightened of doing a hard reset, which may or may not reset the default settings password, lest i should lose internet all together with little or no support from VM at the moment., not being able to log on to the router also means not being able to put in in Modem mode and use a third party router
So if you are having speed issues worth a check to see if all routers around you are on channel 44, and change yours if you can
Just had a thought prob stupid, i wonder if some of the people going to third party routers have had success with curing speed issues ( Wi Fi ) ( as distinct from range issues ) because the new router doesn't use channel 44
