What should I do if my HP Envy 4520 cannot connect to my wireless network?

First, confirm that wireless is enabled on your printer by touching the Wireless icon on the control panel and turning it on if it shows 'Wireless Off.' Then print a Wireless Test Report by going to Wireless > Settings > Print Reports > Wireless Test Report to diagnose connection issues. You should also restart your network components by turning off the router and printer, then turning them back on with the router first, then the printer. If a firewall is blocking communication, temporarily disable it to check if that resolves the issue. (Page 4)
