wireless connection no longer working

[LAGreene]

I have a ink advantage 4675 printer and I cannot  print wirelessly from my laptop. It stopped working about week ago. I have tried reinstalling the full driver software downloaded from the hp website. When the installation reaches activation step the installation stops and gives an error message..

Hi,

Thanks for using the HP Support Community.

Let's try these troubleshooting steps:

Solve wireless problems
1. Make sure the printer is not connected to the network through an Ethernet cable
Wireless does not work if the printer is connected to the network through an Ethernet cable. Disconnect the
Ethernet cable from the printer.

2. Make sure the wireless light is turned on
If the blue light on the printer control panel is not lit, wireless might be turned off. To turn on wireless, touch
or swipe down the tab at the top of a screen to open the Dashboard, and then touch (Wireless), touch
(Settings). Touch Wireless Settings, and then touch Wireless to turn it on.
If the blue wireless light is blinking, it means the printer is not connected to a network. Use the Wireless Setup
Wizard available from the printer control panel to make a wireless connection. Touch or swipe down the tab at
the top of a screen to open the Dashboard, and then touch (Wireless), touch (Settings). Touch Wireless
Settings, touch Wireless Setup Wizard, and then follow the onscreen instructions.

3. Make sure the computer or the mobile device is connected to the wireless network
Make sure your computer or mobile device is connected to your wireless network. If you cannot connect the
computer to the network, contact the person who set up your network or the router manufacturer; there might
be a hardware issue with the router or computer.

4. Restart components of the wireless network
Turn off the router and the printer, and then turn them back on in this order: router first and then printer.
Sometimes, turning off devices and then turning them back on helps resolve network communication issues.
If you still cannot connect, turn off the router, the printer, and the computer, and then turn them back on in this
order: router first, then printer, and then computer

Still have problems? Visit the HP Wireless Printing Center (www.hp.com/go/wirelessprinting). This website
contains the most complete, up-to-date information about wireless printing, as well as information to help you
prepare your wireless network; solve problems when connecting the printer to the wireless network; and resolve
security software issues.
Note: If you are using a computer running Windows, you can use the HP Print and Scan Doctor tool, which can help
solve many problems you might have with the printer. To download this tool, visit www.hp.com/go/tools.

Hope that helps.

We have tried all the suggestions you posted to no avail, so we will have to go to another level.  We even disabled the firewall...nothing.  We suspect that it may be a Microsoft 10 update issue.

Hi,

Thanks for understanding that it's a Microsoft update issue.  We don't normally want to mention that.

Just want to ensure that the wireless on the printer is still working (so we don't chase after the wrong leads).  Are you able to print using your mobile phone to the printer?

If it's working, can you try this (cleans up the system and reinstall the software):

* *Note that if there are other printers installed, these will need to be reinstalled after this.

Step 1. Uninstall the HP Software from your PC. Please follow the steps provided to uninstall the printer software in the link:
Uninstalling the Printer Software (Windows)https://support.hp.com/in-en/document/c02259020
Also, please follow the steps provided below to completely remove the printer software from printer properties.
Steps to remove printer driver files from Print Server Properties:

Step 2. Open the Print Server Properties dialog window by doing one of the following:
• Click the Start menu and in the search field type 'printui /s /t2' (without the quotes), and then press Enter or click it in the search list.
• Open “Devices and Printers” (not Win10)
• Select any printer and then click "Print server properties" at the top of the window.
• Click on the Drivers tab.
• Click on each printer driver and click on Remove

For Win10:
• Press WINDOWS-R on the keyboard to bring up the Run window, type in 'printui /s /t2' (without the quotes), and then press Enter or click OK.
• Click on the Drivers tab.
• Click on each printer driver and click on Remove
• From the Start menu or the Start screen:
• Open “Printers and Scanners”
• Click on each Printer and click “Remove Device”

Step 3. Backup your registry before making any registry changes, the following resource will show you how:

Step 4. Update the registry using the Reg file below
Note: this will change some printer related policies for your PC):

Step 5. Right click the Start menu and select Run. Type Services.msc and press OK.
Locate and stop the Print Spooler service

Step 6. Browse to c:\Windows\System32\spool\drivers.
Rename W32X86 to W32x86.oldRename x64 to x64.old
Note: if any of these folders fail to rename reboot your PC and then continue following the steps starting from Step 5.

Step 7. Restart PC.

Step 8. Finally, reinstall the HP Software.

Hope that helps!
