That will probably depend upon what time of day you and your neighbour have measured your respective speeds. If you measure the speed during peak hours, i'd guess that both of you will be getting pretty poor speeds.
I hope, for your sake, that i am wrong, but i am in area 30 and i'm lucky to get single figure download speeds during peak hours, which strangely enough, is when i am actually most likely to want to use it.
Shame you are not measuring higher speeds, I fully expected to see high traffic in the area but it is quite low. Area streams error free and hub/line parameters all looking good. I wonder if you try a couple of different devices in modem only mode what you would measure Modem mode on your Virgin Media Hub
