Re: Hope they win.
My router does that too, I don't see a problem.
It probably draws some extra power when someone connects to it. In the order of the power consumption of one of the bulbs in the Xmas lighting that the pair probably have all over the house.
It doesn't impact my bandwidth in any significant way (QoS does work, it would seem).
In fact it's so negligible that I actually installed a second "open" spot using Fon. That way, on the move I can benefit from my ISP's hotspots AND Fon's ones, should one of the networks not be available in the area.
