What should I do if the printer won't connect to Wi-Fi?
First, make sure your wireless router or access point is powered on and move the printer closer to it. You can also press the Wireless button and Information button together to run a wireless test and review the diagnostic report for troubleshooting steps. If the Wireless Attention icon is blinking, there is a problem connecting to the wireless network.
