Make sure the wireless security key (password) is entered correctly and precisely. Passwords are case-sensitive, and must be entered with the exact characters, including any spaces, that were used when the password was created.
If you think you have entered the correct password, and you still cannot connect the printer to the wireless router, do one of the following to connect to the network:
- Turn the printer off and then on.
- From the printer control panel menu, turn the Wi-Fi radio off and then on.
