How can I diagnose wireless network connection problems with the HP Photosmart 5520?

From the printer's control panel, touch the Wireless button, then touch Settings, scroll using the down arrow, and touch Print Wireless Test Report — the report prints automatically. Check the top of the report for any test failures, review the Diagnostics Results section, and find the current network name (SSID) in the Current Configuration section. You can also visit www.hp.com/go/wirelessprinting for additional guidance. (Page 5)
