Common Wireless Communication Issues and Steps to Troubleshoot Them

There are many reasons that your printer may be indicated as being "offline" or "not responding".  Basically, the printer and computer are not able to communicate.  Since there are multiple causes for these messages, there are also multiple possible resolutions. The steps below will help in resolving the issue and possibly identify the cause.

Verify Power

  1. Make sure the printer power is on and that no error condition is indicated on the printer. 
  2. Press the power button to turn on the printer.  If the printer will not power on, check the power cord connections. Disconnect and reconnect the power cable at both ends. Then press the power button to turn the printer on.

Select the Appropriate Printer

  1. Before you print, be sure you have the appropriate printer selected. Check the print dialogue box (screen that shows up after you click Print) from the application you’re using in order to make sure you’ve selected your current printer.
  2. If the wrong printer is automatically selected, you may want to set the desired printer as the default printer.
    Setting the default print in Windows   
    Setting the default print on a Mac
  3. If the same printer is listed multiple times, you may have to remove the duplicates and try to print again.  It may be necessary to remove all the listed printers and then reinstall.

Restart the Printer
In some cases it may be necessary to power cycle the printer to potentially reset any error conditions or lost communication.

  1. Simply turn the printer off with the power button on the printer.
  2. Once turned off, disconnect the printer's power cord from the back of the printer.  Wait approximately 30 seconds before you reconnect it.
  3. Once reconnected, use the printer's power button to turn the printer back on.
    If the printer
  4. Once the printer is powered on and is in a ready state, print or scan again.

    ℹ️ If your printer is connected via USB connection, disconnect that from the printer as well as the computer, then reconnect them. In some cases there may be a loose connection.

Wireless Communication

  1. If your printer had been connected wirelessly before, and no hardware changes have been made, you may simply need to reboot your computer.
  2. You may need to reestablish the wireless connection or set your printer up wirelessly if it has not been connected wirelessly before. If your printer has not been setup wirelessly already, or to reestablish a wireless connection, refer to this Wireless Setup article.
  3. If your computer is connected to a Virtual Private Network (VPN), try disconnecting from the VPN to see if it is interfering with printer communication.

Reboot Your Router / Modem

If your router and/or modem is not able to communicate with devices that are usually connected, you should power cycle the router.

  1. First, disconnect the power from your router and/or modem.
  2. Wait approximately 30 seconds and then reconnect them.

    ℹ️ The booting process for the router and/or modem may take several minutes. 

  3. Once a proper connection has been reestablished, if this was the issue, then communication between your devices should be restored.

Reboot Your Computer

In some cases, it may be necessary to restart your computer to refresh connections with the various peripherals such as routers, modems, printers, etc.

  1. Save any needed work and close all open applications.
  2. Shutdown and restart your computer.
  3. Once fully rebooted, try to print or scan again.

Reinstall the Printer Driver

  1. Visit the Canon Support page
  2. Enter the model name of your printer
  3. Select your model name
  4. You will be directed to the Drivers and Downloads page for your printer.
  5. Select and download the recommended driver for your printer model and follow the on-screen instructions to open and install the file.




To all. Canon over the phone helped me to resolve problem. 

After doing all the above maneuvers without result, agent tested I try a different browser and... all worked fine.  My Chrome browser had been corrupted.  So: Uninstalled Chrome, then reinstalled, and computer connects to printer fine and prints all aspects properly now.

What number did you call? I can't find one for my PIXMA printer.

You can reach technical support at: 1-800-652-2666 and find additional support options HERE 

Thanks so much! I'll give it a try.


Lots of hours wasted. My router does not reboot fast enough for the printer wireless setup timeout. Tried using USB to setup wireless but it ends up asking for my Admin password. I cannot think of any reason for this other than it gives Canon and its individual employees unrestricted access to my computer. I have tried calling customer service but got the message to call back later. I have like the various Canon printers for many years, but this experience tells me I have made a mistake and need to send this printer back.


My problem started with the new router. I tried unplugging/repluging everything possible. No good. Did the above and reinstalled the driver. No good. Realizing the drivers were for the older Mac OSs, I finally found 

Connecting the TS6020 to a Wireless LAN via Manual Connect

That did the trick.

I am new and I cannot find the place for asking questions.  It's about my TS9521C printer.  Can someone direct me an "ask question" page?

Found canon Pixma printer problem. My new router interface (sagemcom 8566w) interface was set to accept only WPA2/WPA3 + AES encryption protocol. When set back to only WPA2+AES it WORKED. Problem: old printer, new T Mobile router.
