Re: Connection help with network hardware.
Switch everything off. Your pc, modem, router, her lappy. First try this, plus in modem, wait ten mins, then plug in router, wait ten mins, then power up desktop and lappy, see what happens then.
If that does not work, go into the router settings and check NAT is enabled, look through all the tiny little settings. Do that then do the first thing I told you do to, resetting everything,
