Configuration

My wireless works fine, but every time I log on I have to tick the box that
says "Use Windows to configure my wireless network settings". I do this every
time, but next time I log on it hasn't saved that setting and I have to go
through the process again.

I read somewhere that that box should be ticked by default, but that isn't
the case with me, for some reason.

Does anyone know how I can get Windows to save that as a default?
