Canon Canon PIXMA G6020 MegaTank Wireless All-in-One Inkjet Printer MECH-WIFI Error Fix: Wi-Fi Connectivity Issues — Printer Offline or Not Found

Error code MECH-WIFI on the Canon Canon PIXMA G6020 MegaTank Wireless All-in-One Inkjet Printer means: Wi-Fi Connectivity Issues — Printer Offline or Not Found. The printer drops off the Wi-Fi network, appears "offline" on computers, or cannot be found by mobile devices. Canon PIXMA printers support only 2.4 GHz Wi-Fi — if your router broadcasts 2.4 GHz and 5 GHz under the same SSID, the printer may lose connection when the router steers devices to 5 GHz. Create a separate 2.4 GHz network for the printer if possible. Check the Wi-Fi signal indicator on the printer's LCD — if it shows weak signal, move the printer closer to the router. On the printer, go to Network Settings > Wireless LAN > Print Network Settings to verify it has a valid IP address. If the IP starts with 169.254.x.x, the printer failed to get an address from your router — restart both the router and printer. Assigning a static IP through your router's DHCP reservation can improve reliability.
