Hi. I got myself the fastest 350 virgin media deal. at first my download speed for regular things was between 2 and 6 mb/s while the upload was about 3-4mb/s. I called the automatic support today and after resetting my broadband and whatnot the download speed is about 32-38mb/s which is way better but still not as promised. Oh upload speed remains the same. Considering I can't even get a hold on a real person when calling their support it's really frustrating to hear just "we will fix your problem automatically" and then all I can do is request it again. Honestly if this won't go up I will have to either leave virgin due to their lack of proper and promised service or reduce my speed and pay less. I only decided to get this deal for live streaming video games, it's useless to me if I can't do that with "the fastest" internet in London.
Most likely it is not related to the VM connection but to something on your system. So try this to determine if that is the case.
Make sure your device has a gigabit network card (not just the older 10/100 one) and has the up to date drivers. Use a new Cat5e/6a ethernet cable (old ones do "go off") to connect it directly to the Hub - which you have put into modem mode (to ensure only your device is connected). Check speeds like that first - if they are still low - then, boot up your device into "safe mode with networking" (to disable any software on it that could be limiting speeds). Run the tests at speedtest.net (try on x2 VM servers) on 2 different browsers one of which is a fresh download of one you haven’t previously used (e.g. Firefox, Opera, Safari etc - there are several reports on here of certain browsers causing speed issues). Report back on what that gets.
EDIT: could you also ask a friend/neighbour etc., who has a laptop known to connect at high speeds to their network to test it your network (both cable connected and wifi)
