Try power cycling the router if you have not done so already - turn it off, wait about 10 seconds of more then power back on. Most home routers start backup and are online in about a minute.
The model of the router would be useful to know and your ISP ( at least the type of service, Cable / DSL. If you have cable, you may have to do the same with the cable modem but wait longer before powering it back on and do it before you power-cycle the router.
The grass may not be greener on the other side but it just might have less weeds...
