hi.....ive never heard of such a think, this is a first. most of the time its only ur security key setup that would be an issue if u use one , the other is updating the firmware on the router . most router can take dd-wrt , openwrt , tomato or some other openforum firmware which adds immense functionality . on the security key wep is only numbers , ten to be exact then wpa is a name plus number "ellen1964" very easy . done this all my days never had issues .
