When the HP printer disconnects from WiFi again and again, don’t worry, try these simple fixes:
But before you start, check that the router is on and the WiFi is working fine. Double-check that you have entered the correct WiFi password, and see if the wireless light on your printer is blinking blue.
Solution 1: Do a Simple Restart
Remove the cables from your printer, router, and computer.
Wait for a while and let the network errors clear.
After the wait, plug in the cables and restart all devices normally (start with the router).
Solution 2: Move the Printer Closer to the Router
Place the printer within 8 meters of the router.
Avoid keeping the printer near thick walls, metal objects, or other electronic devices.
Ensure that there are minimal obstructions between your printer and router.
Solution 3: Restore Network Settings
On the printer’s display screen, tap on Wireless or Setup menu.
Select “Restore Network Settings” to clear outdated or broken connections.
Tap on “Yes” to confirm the reset.
Solution 4: Run HP Smart App Setup
On your PC, open a web browser and search “HP Smart.”
Download this app, open it, and select “Add Printer” or “Set Up a New Printer.”
Follow the instructions to connect the printer to your network.
Enter your WiFi password when prompted.
