Will probably move forward with a downgrade. Virgin has sent 3 different engineers to our property in the last two days. The first guy was given no instructions on his work order, and the second guy ran a test that delivered 90MB (or so he claimed) - yet he didn't want to see the speedtest results I saved from the nights and weekends showing between 9-40mb. I don't expect 100MB, but 40% of the speed is a bit much.
My guess is that my area has heavy contention, but it's really frustrated that they don't have tools like BT to run line tests at random points during the day. Everyone in my area is at work during the day, so yeah of course it's going to be fast!
