HP OfficeJet Pro 8710 "failing to find network"

[heman7]

We moved a few months ago, just down the road, using the same internet provider, but our HP 8710 cannot find the network to connect (that is the diagnosed problem on the Wireless Network Test Results)

Tried so far (each 2-4 times):

Restarting router and Printer

Using ethernet cable

Printer distance to router is about 15 feet, but still a problem when 1 foot away and other devices work fine > 50 feet away from router

Reset/restored defaults

Can't do a firmware update because can't connect to the network

My HP Smart app can't locate the printer

Can't find network even when entered the name of the network manually with WPA password,

All other devices in the office have been able to find and connect to the network.

Any other ideas?

Thanks for your help.

@heman7, Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

It sounds like you're dealing with a tricky connectivity issue with your HP OfficeJet 8710 printer, even though other devices are able to connect to your network without problems. Since you've already tried several troubleshooting steps (restarting, using Ethernet, resetting defaults, etc.), let's explore some additional options that might help you get the printer connected:

Check Router Settings:

Network Band: Ensure your router is broadcasting a 2.4GHz network in addition to the 5GHz band, and that the printer is trying to connect to the 2.4GHz network.

Wireless Mode: Verify that your router is set to support 802.11b/g/n.

SSID Broadcast: Make sure the SSID (network name) is not hidden. If it's hidden, even if you manually enter the network name, it might not be detected correctly by the printer.

MAC Address Filtering: Ensure that MAC address filtering is not enabled on your router, or if it is, make sure the printer's MAC address is allowed.

Network Frequency (Dual-Band Router):

Since the printer might be having trouble connecting to the 5GHz band, temporarily disable the 5GHz band on your router and test the connection on the 2.4GHz band alone. Afterward, you can re-enable 5GHz to test if that resolves the issue.

Try changing the Wi-Fi channel on the 2.4GHz band. Sometimes, interference on a particular channel can prevent certain devices from connecting.

Printer’s Network Settings:

Manual IP Address Setup: If your printer is struggling to get a DHCP lease from the router, try assigning a static IP address manually to the printer within your router's IP range. You can do this via the printer’s control panel or through the HP Embedded Web Server (by typing the printer's IP address into a browser once connected via Ethernet).

Check Printer's Wireless Settings: Double-check the printer’s wireless settings from the control panel to make sure it’s set up to connect to your specific network (SSID), and verify the WPA password is correct. 

Reset Network Settings on the Printer:

Since you’ve already reset the printer, try a network-specific reset:

On the printer’s control panel, go to Setup > Network > Restore Network Defaults. This will reset the network settings (Wi-Fi settings) without restoring the entire printer to factory defaults, which may help it re-discover your network.

Use HP Smart App to Reconfigure Connection:

Reinstall the HP Smart app and try the Wi-Fi Protected Setup (WPS) method to connect your printer.

WPS Button Method: On the printer, press the Wireless button to start the WPS setup process. Then, press the WPS button on your router within 2 minutes. This should allow the printer to automatically connect to the network without needing to manually input the SSID and password.

Run HP Print and Scan Doctor (Windows only):

• Download and run the HP Print and Scan Doctor tool. Follow the prompts to diagnose and fix common printing issues.

Update Printer Firmware (Update the firmware on an HP printer | HP® Support)

• Go to the HP Customer Support - Software and Driver Downloads page. Enter your printer model number and search for the latest firmware update. Follow the instructions to download and install the firmware update.

I hope this helps.
