Why Won’t My HP DeskJet 3755 Connect to WiFi?

Before diving into troubleshooting, it’s important to understand the potential causes of the issue. There are several reasons why your HP DeskJet 3755 might not be connecting to WiFi, including:

1. Incorrect WiFi credentials: Entering the wrong WiFi password or SSID (network name) is one of the most common causes of connection problems.
2. Network congestion: Too many devices connected to your router can lead to connectivity issues, causing the printer to struggle with establishing a stable connection.
3. WiFi signal interference: Walls, electronic devices, or other objects between the printer and the router may interfere with the signal.
4. Outdated printer firmware: The printer’s firmware may be out of date, which could prevent it from connecting to the network properly.
5. Router settings: Incorrect or incompatible router settings may prevent the printer from connecting to WiFi.
6. Printer not in wireless setup mode: If the printer is not in wireless setup mode, it won’t be able to search for available networks.
7. Device proximity: The printer may be too far from the router, resulting in a weak or unstable signal.

Let’s explore each troubleshooting method in more detail to resolve the WiFi connectivity issue.

Troubleshooting Steps

1. Check Your WiFi Credentials

One of the most common issues when connecting the HP DeskJet 3755 to WiFi is entering incorrect WiFi credentials.

• Verify the SSID (WiFi network name): Make sure you’re selecting the correct WiFi network during setup, especially if there are multiple networks available.
• Check the WiFi password: Ensure you’re entering the correct password. Remember, WiFi passwords are case-sensitive, so double-check for typos or incorrect capitalization.

If you’re unsure of your WiFi password, you can usually find it on the bottom or back of your router or in your router’s settings.

2. Move the Printer Closer to the Router

Distance between your HP DeskJet 3755 printer and the WiFi router can affect the quality of the connection. If your printer is too far from the router or if there are multiple walls or other obstacles in the way, the WiFi signal may be weak or unstable.

Solution:

• Move your printer closer to the WiFi router and ensure there are no significant obstructions (walls, large metal objects, etc.) that could interfere with the signal.
• Try to place the printer and router in the same room to minimize signal loss.

Once you’ve repositioned the printer, attempt to reconnect it to WiFi.

3. Restart Your Router and Printer

Sometimes, simply restarting both your router and printer can resolve connectivity issues by clearing temporary network glitches.

Solution:

• Restart your router: Unplug the router’s power cord from the outlet, wait for about 30 seconds, and then plug it back in. Allow the router to fully reboot.
• Restart your printer: Turn off your HP DeskJet 3755 by pressing the Power button. Wait for 10-15 seconds, then turn it back on.

After both devices have restarted, try reconnecting the printer to WiFi.

4. Reset the Printer’s Network Settings

If your HP DeskJet 3755 was previously connected to another network or you’ve changed your WiFi settings, resetting the printer’s network settings can help clear any conflicting configurations.

Solution:

• On the printer, press and hold the Wireless button and the Cancel button simultaneously for 3 seconds.
• The printer will reset its network settings, and the wireless light should start blinking, indicating that it’s ready for setup.

You can now attempt to reconnect the printer to WiFi using your preferred setup method (HP Smart app, WPS, or manual setup).

5. Use the HP Smart App for Easy WiFi Setup

The HP Smart app is a convenient way to set up your printer on a WiFi network. It simplifies the connection process and automatically detects your printer and WiFi network.

Solution:

• Download the HP Smart app on your smartphone, tablet, or computer. It’s available for Windows, macOS, iOS, and Android devices.
• Open the app and follow the on-screen instructions to add a new printer. The app will search for nearby printers.
• Once your HP DeskJet 3755 is detected, follow the prompts to connect the printer to your WiFi network by entering your SSID and password.

After successful setup, you should be able to print wirelessly.

6. Verify Your Router Settings

Sometimes, your router’s settings can prevent the printer from connecting to WiFi. Here are some common router settings that may affect connectivity:

• Check for 2.4 GHz network compatibility: The HP DeskJet 3755 only supports 2.4 GHz WiFi networks. If your router is set to only broadcast 5 GHz, the printer will not be able to connect. Ensure that your router is broadcasting on the 2.4 GHz frequency band.
• Enable DHCP: The router’s DHCP setting should be enabled to assign an IP address to the printer automatically.
• Check for MAC address filtering: If MAC address filtering is enabled on your router, you will need to add your printer’s MAC address to the whitelist.

Solution:

• Access your router’s settings by typing your router’s IP address into a web browser (commonly 192.168.1.1 or 192.168.0.1).
• Log in using your router’s admin credentials and navigate to the WiFi or Network settings.
• Ensure that the 2.4 GHz band is enabled, DHCP is turned on, and MAC filtering is either disabled or properly configured to allow the printer.

7. Update Printer Firmware

Outdated printer firmware can lead to connection problems and compatibility issues with modern routers. Ensure that your HP DeskJet 3755 is running the latest firmware version.

Solution:

1. Download and install the HP Smart app on your smartphone, tablet, or computer.
2. Open the app and select your printer from the list.
3. In the app settings, navigate to Printer Maintenance and select Firmware Update.
4. Follow the prompts to download and install any available firmware updates.

Once the firmware is updated, restart the printer and attempt to connect it to WiFi.

8. Use WPS (WiFi Protected Setup) for Quick Connection

If your router supports WPS (WiFi Protected Setup), you can connect the printer to WiFi without entering any network credentials.

Solution:

• Press the WPS button on your router. This will put the router into WPS pairing mode for about 2 minutes.
• On the HP DeskJet 3755 printer, press and hold the Wireless button for 3 seconds to initiate WPS pairing.
• The printer should automatically connect to the WiFi network within a minute.

Once connected, the wireless light on the printer will stop blinking and stay solid.

9. Disable or Adjust Firewall and Antivirus Settings

Sometimes, firewall or antivirus software on your computer or network can block communication between the printer and the router.

Solution:

• Temporarily disable any firewall or antivirus software on your computer or router.
• Try reconnecting the printer to WiFi to see if the firewall was causing the issue.
• If successful, add an exception for the printer in your firewall or antivirus software settings.

Be sure to re-enable your firewall and antivirus protection after testing the connection.

10. Reinstall Printer Drivers

In some cases, reinstalling the printer drivers on your computer can resolve connectivity problems.

Solution:

• Visit the HP website and download the latest drivers for the HP DeskJet 3755.
• Uninstall the existing printer drivers from your computer via the Control Panel or Settings.
• Reinstall the new drivers following the on-screen prompts.

After the installation is complete, try reconnecting the printer to WiFi.

Conclusion

When your HP DeskJet 3755 wireless printer won’t connect to WiFi, it can be frustrating. However, by following the troubleshooting steps outlined above, you should be able to identify and resolve the issue. Start by checking your WiFi credentials, ensuring a strong signal, and using the HP Smart app for a smooth setup experience. If these basic steps don’t work, more advanced solutions like resetting the printer’s network settings, updating the firmware, or adjusting router settings should get your printer back online.

By understanding the potential causes and following the suggested solutions, you can resolve the WiFi connectivity issue and enjoy the convenience of wireless printing again. If problems persist, consider contacting HP customer support for additional assistance.
