Printer won't stay connected to Wi-Fi: how to stop the dropouts

A printer won’t stay connected to Wi-Fi when something keeps breaking the link between it and the router: a weak signal, a band it does not like, an address that keeps changing, or a power setting that switches the radio off. The printer may work after you restart it, then go offline again an hour or a day later. This guide is about fixing those repeat dropouts on a printer that was already connected and working.

If the printer is offline right now and you need it back quickly, start with the printer offline fix, then come back here to stop it happening again.

Step 1: Get the facts from the printer

Print a network configuration page (or wireless test report) from the printer’s control panel. It usually shows:

• the network name (SSID) the printer is connected to,
• the signal strength,
• the printer’s IP address,
• the printer’s MAC address (hardware address).

Keep this page; the steps below use it. If the report shows a weak signal or a network name you do not recognise, you have probably found the problem already.

Step 2: Fix weak signal

Printers often sit in corners, on low shelves or in a different room from the router, and their antennas are modest.

• Move the printer closer to the router, or the router to a more central position, and test again.
• Keep the printer away from microwaves, cordless phone bases, baby monitors and large metal objects.
• If you have a mesh system or extender, make sure the printer is near a mesh node with a strong signal.

As a test, connect the printer with a network cable if it has a network port. If it never drops off when cabled, the Wi-Fi link is the problem.

Step 3: Check the Wi-Fi band

Many printers only support the 2.4 GHz band. Modern routers often broadcast 2.4 GHz and 5 GHz (and sometimes 6 GHz) under one network name and move devices between them. A 2.4 GHz-only printer can get confused by this, especially during setup or after a router restart.

• Check your printer’s specifications for the bands it supports.
• In your router’s settings, make sure 2.4 GHz is enabled. Some routers let you create a separate 2.4 GHz network name or turn off band steering; connecting the printer to a 2.4 GHz-only name can make it much more stable.
• Check that the router’s security mode is one your printer supports. Very old printers may not support newer modes such as WPA3-only networks; a WPA2/WPA3 mixed mode is usually compatible.

Step 4: Stop the IP address changing

Your router hands out addresses to devices, and when it restarts it may give the printer a different one. Computers that remember the old address then report the printer as offline.

The fix is a DHCP reservation: in the router’s admin page, look for a section called DHCP, LAN, address reservation or static lease, and reserve the printer’s current IP address for its MAC address. Router menus differ, so check the router manual if needed. After saving, restart the printer so it picks up the reserved address.

If you added the printer on Windows by IP address, make sure the port in Printer properties > Ports uses the reserved address.

Step 5: Review sleep and power settings

Printers save power by sleeping, and some turn off parts of the network radio in deep sleep. Most wake up when a job arrives, but some computers see a sleeping printer as offline.

• In the printer’s settings, look at sleep, auto off or energy saving options. Auto off, in particular, can switch the printer off completely after a period without use.
• Lengthen the time before deep sleep, or turn off auto off, if dropouts happen after quiet periods.

Step 6: Update the printer firmware

Manufacturers release firmware updates that fix wireless bugs. Check the printer’s settings menu for a firmware or software update option, or the manufacturer’s own support site for your model. Keep the printer on during the update.

Step 7: Check the computer side

Sometimes the printer is still on the network and only the computer has lost track of it. Test this by printing from a phone or a second computer: if that works, the Wi-Fi link is fine and the fix belongs on the computer that reports the printer as offline.

• Windows 11: open Settings > Network & internet, select your Wi-Fi network and make sure the network profile is set to Private. On a Public network, Windows hides devices and turns off network discovery, so a printer added by discovery can disappear. If the printer does not come back in Printers & scanners, see printer not showing up in Windows 11.
• Mac: make sure the Mac is on the same network name as the printer, not a guest network or a phone hotspot. If the printer appears and disappears in Printers & Scanners, or jobs sit paused, our guide to a printer not working on Mac covers the macOS side.
• VPNs and security software: a VPN can route traffic away from your local network, and some firewalls block the discovery protocols printers use. Disconnect the VPN briefly and print again to test.

Step 8: Reconnect after router changes

If you replaced the router, changed the Wi-Fi password or renamed the network, the printer still tries the old details. Reconnect it using the wireless setup option on the printer’s control panel, then remove and re-add the printer on your computers so they use the new connection. If you need a full first-time setup walkthrough, use the manual or the manufacturer’s setup instructions for your model.

Summary table

Pattern	Likely cause	Fix
Drops after the router restarts	IP address changed	DHCP reservation
Drops after quiet periods	Deep sleep or auto off	Adjust energy settings
Drops randomly, weak signal on report	Distance or interference	Move printer or router, use a cable
Never stable since a new router	Band or security mode	2.4 GHz network, compatible security
Started after a firmware or router update	Bug or changed settings	Update firmware, reconnect

When the connection is stable but printing still fails

Once the printer stays on the network, any remaining problems are usually in the print queue or the driver rather than the Wi-Fi. Jobs that stay stuck point to the print spooler fix; an “Error” status under the printer’s name is covered in printer in error state.
