Post on behalf of a mate.
He was on 2meg virgin cable, and was getting 1meg on wireless, so he bought some powerline plugs, plugged them in and started getting 2meg speeds again ! He then rang virgin media and asked to upgrade him to 10meg and they said it would take 30 minutes, this was 2 days ago and various speedtests show he's getting 500kb, (0.5meg), and 90 upload, he's reformatted his computer and is still getting slow speeds. They are 85mbps plugs btw. He has restarted his modem numerous times and still not improving.
