My speed has finally been doubled, honest Guv.
Last weekend my connection suddenly went to 20Mb from 10. Before the speed doubling I had a generally rock steady 10Mbps. Now I have a wildly fluctuating anything from less than 1 to apeak of 14 Mbps, with it generally running at about 11 to 12. Not exactly what Usain Bolt promised on the telly.
