I assume someone somewhere will be able to get 20mbps, perhaps they live next door to plusnet!!
Personally I would be happy with 5mbps, despite complaining to plusnet I rarely get above 3mbps, this evening only 2.2, was getting 5mbps. I really need to get on line at 04.00 hrs, no doubt I would get 5 as I would be the only one on line.
