Quick Answer

Move the printer closer to the router, assign it a static IP address, and reduce or disable its power-saving sleep mode.

Common Reasons my printer keep disconnecting

Weak or fluctuating signal

A marginal WiFi signal can hold a connection briefly before dropping under load.

A dynamic IP address

If your router regularly reassigns IP addresses, the printer's address on your computer becomes outdated.

Aggressive power-saving mode

Some printers disable their WiFi radio during sleep to save energy, appearing as a disconnect.

Router firmware or channel congestion

Interference from neighboring networks can intermittently knock devices off the WiFi.

Quick Checks Before Troubleshooting

Before you start:
  • Check the printer's WiFi signal strength indicator, if it has one.
  • Note how long after being idle the printer tends to drop.
  • Check whether other devices in the same room have similar WiFi issues.

1. Move the Printer Closer to the Router

1

Reducing distance and obstacles improves signal stability significantly.

2. Assign a Static IP Address

2

Reserve a fixed IP for the printer in your router's DHCP settings so it never changes.

3. Adjust Power-Saving Settings

3

Lower or disable the printer's sleep timer in its own settings menu.

4. Change the WiFi Channel

4

In your router settings, switch to a less congested channel to reduce interference.

5. Update Router and Printer Firmware

5

Both devices should run current firmware to avoid known connectivity bugs.
