I know how to reset my router password, by sticking a pin in the re-set button, this sets it back to factory settings so the password will be as that listed on the bottom of the router. I can also change it through my Virgin account. I changed it as I have a wifi blocker app to try to kick my son off his endless gaming. However, the little tyke has found out that if he sticks a pin in the reset button, this will revert the password back to that on the bottom of the router, then my wifi blocker won't pick up the router! My way round this next is to buy a lockable box to stick the router in so he can't set the re-set button. However, what happens if he unplugs the router - does the router go back to it's default settings? I have tried Mac filtering which doesn't work frustratingly.
