Canon Pixma TR8620 Not Connecting to Wi-Fi — How to Reconnect

If your Canon Pixma TR8620 printer suddenly stops connecting to Wi-Fi or won’t respond when you try to print, you’re not alone. Many Windows users experience this problem after a system update or when their computer has trouble recognizing the printer. Thankfully, the issue often comes down to simple communication problems between your computer and your printer.

In most cases, this happens because your computer’s connection software (the background program that helps your printer talk to your computer) has become outdated, missing, or damaged. The good news is that you can fix this quickly by updating or reinstalling that connection software — and you don’t need to be a tech expert to do it.

Below, you’ll learn the easiest and safest ways to get your Canon Pixma TR8620 back online and printing again.

Why Your Canon Pixma TR8620 May Stop Responding or Lose Wi-Fi Connection

When your printer suddenly stops connecting to Wi-Fi or disappears from your list of available devices, it can feel like the printer itself is broken. But in many cases, the printer is fine — it’s the link between your computer and printer that’s causing the trouble.

That link depends on a small program on your computer that helps both devices communicate. Over time, this program can become outdated, damaged, or accidentally removed when you update Windows or install other software.

When that happens, you may notice:

• Your printer won’t connect to Wi-Fi.
• Printing jobs stay stuck in the queue.
• The printer shows as “offline.”
• You see error messages that say “Printer not detected” or “Cannot communicate with printer.”

Updating or reinstalling your printer’s connection software (also known as a printer update) can usually fix these issues in minutes.

How to Fix Your Canon Pixma TR8620 Connection Manually

If you prefer to do things yourself, you can also update your printer’s connection software manually. There are two reliable ways to do this: through Canon’s official support page or through the Windows Device Manager tool.

Let’s go through both options step by step.

Option 1: Update Using Canon’s Official Support Website

Canon provides updates and tools for its printers on its support website. You can download the latest software for the Pixma TR8620 directly from there.

Follow these steps carefully:

1. Go to the Canon Support Website
   • Open your web browser and visit the official Canon USA Support page.
   • Type “Canon Pixma TR8620” in the search bar, then click on your printer model from the list.
2. Choose Your Operating System
   • Canon’s website usually detects your version of Windows automatically. If not, select your Windows version manually from the drop-down list.
3. Download the Recommended Software
   • Under the “Drivers & Downloads” section, look for the printer software or communication tool.
   • Download the latest version available.
4. Install the Software
   • Once downloaded, open the file and follow the on-screen instructions to complete the installation.
   • Restart your computer after the installation is finished.
5. Reconnect Your Printer to Wi-Fi
   • On your printer’s screen, select Wireless LAN Setup from the Settings menu.
   • Choose your Wi-Fi network and enter your password.
   • After reconnecting, try printing a test page from your computer.

If the print test works, your printer is back online.

Option 2: Update Through Windows Device Manager

If you don’t want to visit websites, Windows already includes a built-in tool that can help you search for updates.

Here’s how to use it:

1. Open Device Manager
   • Right-click the Start button and select Device Manager from the list.
2. Find Your Printer
   • Expand the section labeled Printers or Print queues.
   • Locate Canon Pixma TR8620 in the list.
3. Update the Software
   • Right-click on the Canon Pixma TR8620 and select Update driver.
   • Choose Search automatically for updated driver software.
   • Windows will look online for the latest update and install it if available.
4. Restart Your Computer
   • After installation, restart your computer to apply the changes.

Once your computer restarts, reconnect your Canon Pixma TR8620 to your Wi-Fi network and print a test page to confirm that everything is working properly.

Additional Tips for Keeping Your Printer Working Smoothly

• Restart Your Printer and Router — Sometimes a simple restart can refresh your network connection and fix temporary glitches.
• Check Wi-Fi Signal Strength — If your printer is far from your router, move it closer to ensure a stronger signal.
• Keep Your System Updated — Regularly updating your Windows system helps prevent compatibility problems.
• Use the Correct Software — Avoid installing random printer tools from unknown websites. Always use Canon’s official page or a trusted tool like DriverAssist.

When to Use DriverAssist Again

If your Canon Pixma TR8620 ever starts showing the same problems — printing delays, offline messages, or failed Wi-Fi connections — it usually means your computer’s connection software has gone out of sync again. You can save time by using DriverAssist to scan and automatically fix the problem before it becomes more frustrating.
