in this kind of problem , you need to do the powercycling of the modem, router and phone. once it will done . then try to connect your phone with your wifi.
if you are still getting the same problem . then go to wifi settings on your phone and then tap on your network and then click on forget or remove your network .
after that try to connect it with the wifi . surely it will connected to the wifi .
if it is still not connecting to the wifi .then you need to update the firmware of the router .
