When a Canon printer is not connecting to Wi-Fi, the issue is often caused by incorrect network settings, weak signal strength, outdated firmware, or router problems. Restarting the printer and router, re-entering the Wi-Fi password, and running the Canon wireless setup can help. Updating printer drivers and placing the printer closer to the router also improves connection stability. https://printerithelp.com/canon-printer-support/canon-printer-not-connecting-to-wifi
