Canon Printer Won't Connect to WiFi: 8 Fixes
Canon printers are reliable but WiFi connection issues are frustratingly common, especially after router changes or network updates. Here are the most effective fixes.
Fix 1: Check Your WiFi Band
Most Canon printers only support 2.4GHz WiFi, not 5GHz. If your router broadcasts both bands with different names (e.g., "HomeNetwork" and "HomeNetwork_5G"), make sure you're connecting your Canon printer to the 2.4GHz network. If your router uses the same name for both bands (band steering), you may need to temporarily disable 5GHz in your router settings during printer setup.
Fix 2: Reset Canon Network Settings
On your Canon printer: press and hold the Stop button until the orange lamp flashes 15 times, then release. This resets all network settings to factory default. After the reset, reconnect to WiFi from scratch using the Wireless LAN Setup in the printer's menu.
Fix 3: Use Canon PRINT App
Download the Canon PRINT Inkjet/SELPHY app on your smartphone. The app provides a guided WiFi setup that's significantly more reliable than using the printer's control panel alone. Open Canon PRINT → tap the printer icon → Set Up New Printer and follow the step-by-step instructions. The app automatically detects common connection issues and suggests fixes.
Fix 4: WPS Setup Method
On your Canon printer: press and hold the WiFi button until it flashes once, then release. Within 2 minutes, press the WPS button on your router for 3-5 seconds. The WiFi light on the printer will flash rapidly then turn solid when connected. This bypasses password entry entirely and is the most reliable connection method for supported routers.
Fix 5: Check Router Security Settings
Some router security settings block printer connections. Log into your router admin panel (usually 192.168.1.1 or 192.168.0.1) and check: AP isolation or client isolation is disabled, MAC address filtering isn't blocking your printer, and the printer's IP address isn't being blocked by any firewall rules. These settings are often enabled on routers provided by internet service providers.
Fix 6: Update Canon Firmware
Outdated printer firmware causes WiFi compatibility issues with newer routers. Check for firmware updates via the Canon PRINT app (Printer Settings → Firmware Version → Check for Updates) or through the printer's menu (Setup → Device Settings → Firmware Version → Update). Firmware updates frequently resolve WiFi connection problems.
Fix 7: Move Printer Closer to Router
During initial setup, interference and distance cause connection failures. Temporarily move your printer to within 3 metres of your router to set up WiFi, then move it to its permanent location once connected. Walls, appliances, and distance all reduce WiFi signal strength — if connection drops frequently, consider a WiFi extender near the printer's permanent location.
Fix 8: Full Factory Reset
If nothing else works: on your Canon printer, go to Setup → Device Settings → Reset Settings → Reset All. This returns the printer to factory defaults. After the reset, set up WiFi again from scratch. While time-consuming, a full reset resolves persistent connection problems caused by corrupted settings.
