My FiOS Internet service was a MI424WR Rev I router. Everything worked no issues. Then I upgraded to the new Quantum fios gateway router. Now 3 (2 of one type 1 of another different manufactures) of 10 wifi devices will not connect to the router. We get password incorrect error? Was on the phone with tech for 2 hrs! No help. The answer is it's not the router. Even though all devices worked on the previous equipment. We have tried multiple items; Like legacy settings - password change - SSID change individually and together. Router reset- device rests - just trying to connect the device that will not connect with nothing else connected etc.
You are saying in essence 3 out of 10 devices won’t or cannot connect to internet.
you have to take each device (one at a time) select the network SSID (name) and select forget this network. Turn the device on and off. Then select WiFi again. You should see the name of your WiFi network. Click on connect and then enter the password for your 2.4 or 5 Ghz network. Some devices connect to either or or both.
enter the password exactly. It should connect with no issues.
you are to enter the WiFi password from the sticker on the Quantum not the master password for router access. Look at the WiFi SSID and password and enter it exactly.
if you changed the password on the Quantum for WiFi it will have to be the one you changed to.
