timppu: That is certainly good news, so now I know I should be able to achieve the top speed without having to be connected with an eth cable to the router. I guess I just need to buy a suitable USB wifi adapter for my older laptop, they don't seem to cost that much.

I just tried e.g. downloading and installing Dark Souls from Steam to my newer laptop. I am not quite used to several gigabytes of data coming tp the PC in a couple of minutes. :) I'm yet to test how fast I can download my GOG games, this evening I'l check it with gogrepo...
