Step 1: Verify the Network status logo on the display screen.  If the logo is shown, or if only the mobile logo is popping, then wireless LAN gets disabled.  Now pick the Setup option on the HOME screen. Navigate to Device settings and then LAN settings.   Choose your wifi and now make a choice of Enable with Enable/disable Wi-Fi. Note  If the disabled wifi logo is shown up, check the following to ensure that the printer setup is thorough or the wireless router settings to associate are accurate. (Note: If the User management settings is already enabled, then user selection screen is shown preceding to the HOME screen.) Step 2: Do ensure that the printer setup is done on the computer in a successful manner. Step 3: Ensure that the wireless router access point and printer settings configure well. ➤ Ensure that the network configuration of the printer {network key (password) or network name (SSID)} is same as that of the router. ➤ To verify the wireless router settings, go through the instruction manual given here. ➤ To verify the printer’s network name (SSID) set, show it by using the printer’s operation panel or take a printout of the details of the printer’s network setting. ☛ Show on the display screen. *. LAN settings ☛ Take a Print of the network settings. *. Printing Network Settings (Note: Use a 5 GHz or 2.4 GHz frequency band to associate with a wireless router. Configure the printer’s network name (SSID) set with that of the wireless router 5 GHz or 2.4 GHz frequency band.) Step 4: Ensure that the printer is not positioned very far away from the router. If the distance between wireless router and the printer is very far, then wireless communication gets poor. Position the wireless router and printer such that they are in close proximity. Step 5: Ensure that the wireless signal is good. Keep a check on the signal strength and move the wireless router and printer if required. ☛ Position the wireless router and printer where there are zero things between them. Wireless association between different floors or rooms is generally bad. Wireless associations will be hampered by the blockage of building materials consisting of concrete/metal. If you notice that the printer is not able to communicate with the PC via Wi-Fi because of a wall, then position the computer and the printer in the same room. ☛ Also, if an electronic gadget like a microwave oven releases radio waves matching the wireless router’s frequency bandwidth, it can cause hampering. Position the wireless router in such a manner that it is free from interference sources. ☛ Verify the signal quality on the display screen. Step 6: Ensure that the Enable bidirectional support is picked in the Ports sheet under the Printer properties box. If not, then enable bidirectional support. Step 7: Turn off the security software's firewall ☛ If the security software's firewall is switched on, then a message appears telling you that Canon software is trying to reach the network. If at all this disclaimer message shows up, set the antivirus software to allow the access. ☛ If you are employing any software programs that swap among network environments, verify the settings. Step 8: If printer is associated via an AirPort Base Station through LAN, ensure that you employ alphanumeric characters for the network name (SSID) for Mac OS. If the problem is not resolved, go for a redo setup.
