Wifi router no internet

well first of all, that router is a rather old model. How long have you had it for? If you reset it and it still doesn't connect maybe that Internet port went bad and you'll have to get a new one. If the four LAN ports work on that router you can convert it into an access point later and will work with another router as the main router and that router as the access point. In my opinion its time to get something newer and save that one as an access point.
