I've just upgraded my cable modem and wifi router (Arris G36) and I'm trying to update my wifi network on my MG7720 printer. When I go into Wireless LAN Setup then Standard Setup and select my new router it says "Connecting to the wireless router..." then I get an error message saying 'Failed to connect to the wireless router" instead of prompting me for a password.
I've never use this printer on this new wifi network so there shouldn't be a password stored.
I've already reset all setting on the printer and it has not worked.
Also, my router does not have a WPS button.
