I remember reading an email from Virgin media a while ago stating they were going to increase the speed from 75 to 100 in December but couldn't find it so thought I had imagined it. I Just logged into my Virgin account and found a message confirming the upgrade but will have to wait a little longer.
If it helps i live in the LU4 area of luton my statistics are Ping 0 ms,Download 111.43Mbps and Upload 6.38Mbps i have hub 3 not the best hub it has it's faults that i sorted the Virgin engineers couldn't (Cut me off line after 20 minutes) Puma 6 chipset (Look it up).I think Virgin have gone to 100,200,300Mbps tiers,i used Ookla for my speed test,we've come a long way from dial up have we not.
Don't knock it. I'm supposed to be on 150Mbps (via several Free upgrades) but have never got anything near that. I normally get between 40 and 50 on most days but it can vary considerably. I just checked it and am getting 37Mbs at the moment. I've spent literally hours on the phone to the Tech guys and they've failed miserably to improve matters.
BT have you tried their forum they are usually quite good at sorting things out. Maybe not the quickest but they get there in the end.
Are you actually connected by their Cable. Just looks like Coax cable. If you are not getting what you pay for and it seems that you are not tell them you want an engineer out to investigate. To high a signal from them or to low a signal from them will interfere with you speeds.
I am supposed to get 75mbps and at the moment getting 110mbts. Whatever I have had to pay for I have never had lower speed. Temporarily had lowers speed but the engineer always fixed it when asked to come out.
I have been with them for about 10 years and probably complained 3 or 4 times that there were problems and fixed every time.
