If your printer can't find your Wi-Fi network, keeps dropping its connection, or won't accept your password, the cause is almost always one of six things. Work through these in order — about 90% of Wi-Fi printer problems are solved by Fix 1, 2, or 3.
Fix 1 — Use the 2.4 GHz band, not 5 GHz
This is by far the most common cause. Most home printers only support 2.4 GHz Wi-Fi, but modern routers broadcast both 2.4 GHz and 5 GHz. If both bands share the same Wi-Fi name (SSID), the printer often tries 5 GHz and fails silently.
- Log into your router's admin page (usually
192.168.1.1or192.168.0.1). - Find Wireless Settings.
- Either (a) temporarily disable the 5 GHz band while you connect the printer, or (b) give the 2.4 GHz band a separate SSID (e.g. HomeWiFi-2.4) and connect the printer to that one.
- Once connected, you can re-enable 5 GHz — the printer will stay on 2.4 GHz.
Fix 2 — Restart printer, router and PC (in order)
Sounds basic, but the order matters and most people skip the wait.
- Power off the printer.
- Unplug the router from power and wait 60 seconds.
- Plug the router back in. Wait until all its lights are stable (usually 2 minutes).
- Power on the printer.
- Reboot your PC.
- Try printing.
Fix 3 — Re-enter Wi-Fi credentials from the printer's panel
If your Wi-Fi password was changed or auto-rotated, the printer is still using the old one. Re-enter it directly on the printer's display:
- Touchscreen printers: Settings → Network → Wireless Setup Wizard.
- Button-only printers: Hold the Wi-Fi or Wireless button for 3–5 seconds, then run the setup using the manufacturer's mobile app (HP Smart, Canon PRINT, Epson iPrint, Brother iPrint&Scan).
Fix 4 — Use WPS push-button if supported
Most routers and most Wi-Fi printers support WPS, which skips the password entirely:
- On the printer, navigate to Wi-Fi setup and select WPS (or "Push Button" method).
- Within 2 minutes, press the WPS button on the back of your router.
- The printer should connect within 30–60 seconds.
If your router doesn't have a WPS button (newer mesh systems often disable it), use Fix 3 instead.
Fix 5 — Move the printer closer (signal strength)
Printers have small antennas. If the signal at the printer's location is below about −65 dBm, connections become flaky or impossible.
- Print a Wireless Network Test Report from the printer's menu (every brand has this).
- Check the signal strength — if it says Weak or Fair, move the printer closer to the router and try again.
- If you can't move the printer, consider a Wi-Fi extender or a mesh node near the printer.
Fix 6 — Reset network settings on the printer
If you've changed routers, ISPs, or Wi-Fi passwords multiple times, the printer's saved network config can get into a bad state. Most printers have a "Restore Network Defaults" option:
- HP: Settings → Network Setup → Restore Network Defaults.
- Canon: Setup → Device Settings → LAN Settings → Reset LAN Settings.
- Epson: Setup → Restore Default Settings → Wi-Fi/Network Settings.
- Brother: Menu → Network → Network Reset.
After resetting, set up Wi-Fi from scratch using Fix 3 or Fix 4.
Still won't connect?
If you've tried all six fixes and the printer still won't join Wi-Fi, the cause is usually router-side: MAC filtering, AP isolation, IPv6-only mode, or a guest-network restriction. These are hard to spot without seeing your specific router model.
