Fixing Network and Wi-Fi Printer Connection Problems

Overview

Network printers rarely “forget” how to print. Far more often, something about the network changed: a new router, a power cut, a password change or a computer joining a guest network. These steps find what changed and put it right.

Step by step

1. Print a network configuration page

   Use the printer’s own menu. It shows whether the printer is connected, its IP address and the network name it joined.

2. Check both devices are on the same network

   Your computer and printer need to be on the same network. Guest networks and some mesh setups isolate devices from each other.

3. Check the signal

   If the configuration page shows weak signal, move the printer closer to the router or away from metal cabinets and appliances, or use a network cable if one is available.

4. Re-add the printer by its current address

   Remove the old printer entry from your computer and add it again, so the computer uses the printer’s current address.

5. Make the address stable

   If the printer keeps going offline after restarts, ask whoever manages the router to reserve its address so it does not change.

Common causes

The printer’s address changed

The computer is still looking for it at the old address.

Router or password changes

The printer is still trying to join the old network details.

Weak or crowded Wi-Fi

Connections drop intermittently, especially during large jobs.

Sleep and power settings

Deep sleep modes can make some printers disappear from the network until they wake.

When to ask for help

Stop and get help if any of these apply:

• The printer will not join the network at all after you re-enter the details.
• Only some computers or phones can print to it.
• It drops offline repeatedly even with good signal.
• You need several printers set up consistently across an office.
