Canon printers usually fail Wi-Fi setup because the signal is weak, the router is using a 5GHz-only or hidden network the printer cannot handle, or the printer is still holding an old saved password. A fresh setup attempt is usually faster than trying to repair the old profile.
Does this affect you?
Use this guide if the Canon printer cannot find Wi-Fi, fails after entering the password, connects briefly then drops, or must be re-added after a router change.
Reconnect with the printer Wi-Fi setup wizard
This clears the broken attempt and joins the network again.
- Move the printer close to the router temporarily.
- On the printer, open Setup > Device Settings > LAN settings > Wireless LAN setup, or the closest matching menu.
- Choose standard wireless setup and select your Wi-Fi network name.
- Enter the password exactly, including capitalization. If the network is hidden, consider broadcasting the SSID during setup.
- Confirm the router has a 2.4GHz network. If it uses a combined band name, temporarily split 2.4GHz and 5GHz so the printer can join 2.4GHz.
- Print a network configuration page to confirm the printer has a valid IP address.
- Add the printer again on Windows or Mac after it is connected.
Fix a connection that drops later
Use this when setup succeeds but the printer disconnects after minutes or hours.
- Check printer power-saving settings and temporarily disable automatic power-off or very deep sleep.
- Set a DHCP reservation or fixed IP for the printer in your router so its address does not keep changing.
- Update Canon printer firmware from Canon Support if your model has an update.
- Restart the router by unplugging it for about 30 seconds, then let Wi-Fi fully return.
