Well no problems to date, slowest i have seen is @ 65mbs. Doesnt that also apply to cable supply? Thats what Virgin have been telling me until i binned them.And if everyone within range of that mast also tried to use it like you are, you would see a big change in performance, and reliability of calls, mobile phone companys activity disconnect voice calls if more data capacity is required.
The 4g has been a lot more stable and reliable than the Virgin cable.
