A Canon printer not connecting to WiFi is a common issue caused by weak signals, incorrect network settings, or outdated firmware. To fix it, ensure the printer is within range of the router, verify the WiFi password, and connect to a 2.4GHz network. Restart your printer and router, then use the Canon PRINT Inkjet/SELPHY app or WPS method for setup. Updating drivers and firmware often resolves compatibility issues. If problems persist, reset the printer’s network settings and reconnect. Following these steps helps restore a stable wireless connection, allowing smooth, hassle-free printing from any device on your home or office network.
