Hi @John_Baptist123,

Welcome to the HP Support Community. 

I'd be happy to help you! 

Print a Wireless Test report to test your printer's wireless functions, such as signal strength and security settings, and search for similar networks, which might cause interference.

Print a Wireless Network Test Report

• Print a Wireless Network Test Report to find information about your printer network connection or to troubleshoot connection issues.
• Print a Wireless Network Test Report:
• Inkjet printers with a control panel menu: Open the Wireless, Network Settings, or Setup menu to locate the list of available reports.
• Most inkjet printers without a control panel menu: Press the Wireless and Information buttons at the same time, or press the Wireless and Start Copy Black buttons at the same time.
• LaserJet printers: Press and hold the Wireless button for 10 seconds or until the Ready light blinks, or go to the Wireless menu and select Wireless Network Test.
• Laser NS and Neverstop Laser printers: Press and hold the Resume and Wireless buttons for 3 seconds.
• DeskJet 6000 and 6400, ENVY 6000 and 6400, and Tango printers: Touch and hold the Information button until all control panel buttons light up, and then touch the Information and Resume buttons at the same time.
• Review the information on the report, and then follow any instructions provided to troubleshoot connectivity problems.
