problems connecting an HP Officejet Pro 8100 to a wirelss network

[tegrabowski]

       I have moved and am having problem getting the HP 8100 printer to connect to the new wireless network.  When I set up the printer for a wireless connection it comes back with the error: Your printer failed to join the wireless network.  Issue: Incorrect wireless password.

    I used the setup option that detects the computer's wireless connection to the router and it had the correct settings for the network and the wireless password.  The printer then fails to connect to the network due to an incorrect password.  The printer wireles network test results page shows:

Wireless on --  PASS

Wireless Working -- PASS

Connected -- not run

Network name Found -- PASS

The network name show as the correct network name

     The router sees the printer and its MAC address as an auto-learned Wi-Fi Device.  The WPS option to connect also does not work.  I have also tried to connect onboth a laptop and a desktop wirth no success. 

    How can I get the printer to connect to the network?

Hi @tegrabowski,

Welcome to the HP Support Forums!

I see that you're unable to reconfigure the wireless on your HP Officejet Pro 8100 ePrinter since you moved. I would be happy to look into this with you and please remember to return to this thread and mark 'Accept as Solution', if I have successfully helped you resolve the issue. If you wish to say 'thanks' for my effort to help, click the 'thumbs up' to give me a Kudos.

I recommend that your restore the network defaults on the printer and try reconfiguring the wireless again. 

Reset network settings:

1. To reset the administrator password and network settings, press and hold (Wireless) button and (Cancel) button for three seconds.

NOTE: Print the network configuration page and verify that the network settings have been reset.

Source: User Guide

Follow the steps in this guide to reconfigure the wireless: 

• Setting Up the Printer for a Wired or Wireless Network for the HP Officejet Pro 8100 ePrinter

Tips for successful wireless connection:

• What encryption type are you using? HP recommends WPA or WPA2. 
• Use a unique network name (SSID).
• Avoid using Mac Address Filtering on the router. 
• Make sure you have 802.11g enabled.
• The printer cannot connect to the 5.0 GHz network. If you have a dual-band router, the 2.4 GHz, and 5.0 GHz network names should not be the same. Rename the 5.0 GHz network.
• Do not hide your SSID (network name).
• Change the router to a fixed wireless channel like 1, 6 or 11, which has less traffic.
• Do you have a switch or an additional router?
• Do not use a guest network (SSID).
• Disable UPnP on the router.
• Set router to 20Mhz only, or 145Mbps depending on the router.
• Update the router's firmware.

I hope this information is helpful. Please respond to this post with the results. Good Luck!

Hi @tegrabowski,

Thanks for getting back to me.

Make sure that your computer is on the 2.4 GHz network, otherwise, the computer and printer cannot communicate.  

Please download and run the Print and Scan Doctor and check the SSID and passphrase used on the computer. 

How do I view my printer's network connection information?

You can use HP Print and Scan Doctor to view the printer's IP address, Mac address, signal strength, connection, network, and security types.

1. On the desktop, double-click the HP Print and Scan Doctor icon  to open the tool.

2. Under the Product heading of the Welcome screen, click the name of your printer, and then click Next.

   Figure : Click the name of your printer

   

3. In the HP Print and Scan Doctor window, click Printer.

   Figure : Click Network in the HP Print and Scan Doctor window

   

4. In the drop-down menu, click Show Advanced Info.

   Figure : Click Show Advanced Info in the drop-down menu

   

5. Review the information that displays to find the IP address, Mac address, signal strength, connection, network, and security types, and other network information about the printer.

   Figure : Example of the Advanced Info window

   

6. If your printer is connected to a wireless network, you can click Show Wireless Info for more information about your wireless connection, such as the SSID name, wireless status, signal strength, and security type.

   Figure : Example of the Wireless Info window

   

What were the results when you ran the Print and Scan Doctor (did it print or scan, any error messages)?

If the issue persists, follow these steps. 

Option two: The 'Wireless Setup Using a USB Connect' screen displays

Follow these steps to connect your printer to the wireless network using a USB cable.

Video of connecting your wireless printer to a wireless network with a USB cable

The following video demonstrates how to connect your wireless HP printer to a wireless network through a USB cable.

If you have trouble viewing the video or to view the video in a different size, click here to play the video on YouTube.

1. Temporarily connect a USB cable from your HP product to your computer when prompted so that your network information can be communicated to the product.

2. Follow the on-screen instructions to complete the software installation and wireless network setup for the HP product.

If the issue persists, I recommend that you contact HP Phone Support, there could be a problem with the wireless radio on the printer.

Please respond to this post with the results. Good Luck!

Just an FYI here, this is incorrect data.  Your printer will work just fine on the 2.4Ghz band with your computer on the 5Ghz band.   It's the IP address that counts, not the SSID band.  You may have to check your router and make sure AP isolation is unchecked.

The computer is on the 2.4 GHz network. Below is the information from the Print and Scan Doctor. It will only find the printer when connected by the USB cable. It is picking up the current network and network password. This password has been connection all the other devices to the network.

Trying to convert the USB connection to wireless also fails with the same “failed to join due to the incorrect password” error. The Wireless Network Test results report from the printer have the following diagnostic results:

>Wireless

            -wireless on     PASS

            -wireless working        PASS

            -signal quality              Not Run

>Connectivity

            -Connected     Not Run

            -disconnect count total           13

            -disconnect count (last hour)              0

            -disconnect count (last 24 hours)        0

>network

            -Network Name(SSID) found                                    PASS

            -other networks detected matching your network name (SSID)        no

            -wireless networks detected               3

The printer worked previously on the network before our move but it was a different router. It is possible that something happened to the printer in the move but it works fine other than the wireless connection issue. I will try to call HP Phone Support.

Hi @tegrabowski,

Thanks for getting back to me.

I see that you have confirmed that the password that you're entering is correct and is the same as the one on the computer.

As a test, please connect the printer to your router using an ethernet cable to see if the printer connects to the network. Print the network configuration page to confirm that it is connected and try re-adding the printer to the computer again.

If the issue persists, I suggest that you perform the Semi-Full Reset on the printer. Please call HP Phone Support. 

Check Warranty Status: http://h20564.www2.hp.com/hpsc/wc/public/home 
Repair fees might apply for out-of-warranty printers.
What you can do, is use the following link to create yourself a case number, then call and it may help speed up the call process: 
Step 1. Open link: http://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect 
Step 3. Scroll down to "Still need help? Complete the form to select your contact options" 
Step 4. Scroll down and click on HP contact options - click on Get phone number 
Case number and phone number appear. 

Please respond if you have any concerns. I hope you have a great day!

I've tried all the solutions proposed in this thread and my printer still won't connect. I get the same message. Unfortunately, it would be cheaper to buy a new printer than pay for help with HP. I do think HP should help people connect their products for free when it's their products that are faulty. My system worked fine before I moved and there's a different router. The router is still a major brand (Linksys) so the printer shouldn't have so much trouble working in WiFi mode.
