Repeated disconnects are typically caused by a weak signal, an unstable IP address, or the printer's power-saving mode dropping the WiFi radio.
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If your router regularly reassigns IP addresses, the printer's address on your computer becomes outdated.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
- 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
Reducing distance and obstacles improves signal stability significantly.
2. Assign a Static IP Address
Reserve a fixed IP for the printer in your router's DHCP settings so it never changes.
3. Adjust Power-Saving Settings
Lower or disable the printer's sleep timer in its own settings menu.
4. Change the WiFi Channel
In your router settings, switch to a less congested channel to reduce interference.
5. Update Router and Printer Firmware
Both devices should run current firmware to avoid known connectivity bugs.
What If It's Still Not Fixed?
