A top tip when applying security and passwords. Write them on a sticker and stick this to the router. Lets face it if someone is standing looking at the router, they will not need the wirless passkey to get into the network, or the password to alter the router settings, just to plug some CAT5 into a free port on the router.
Reconfiguring it when you have forgotton your password and need to press the reset button to get the factory defaults having spend a good while setting up all the security and had it working stablely for months is not something I recommend.
