What should I do if the HP OfficeJet 4650 cannot connect to my wireless network?

First, confirm that wireless is enabled on your printer by touching the Wireless icon on the control panel — if it shows 'Wireless Off,' go to Settings and turn wireless on. Then print a Wireless Test Report by going to Wireless > Settings > Print Reports to diagnose the issue. If the report indicates the printer is not connected, use the Wireless Setup Wizard to reconnect, and also check that your firewall is not blocking communication. (Page 4)
