Cannot connect HP Envy 5540 to Router - Will not accept router security key

[Telemick]

One of my computers no longer connects wirelessly to HP Envy 5540 (It has worked fine for several years) Other computers still work without any problems.

When I click on the printer under Wifi devices, I have set it to connect automatically but it does not.

I then select connect and it asks for an eight digit PIN or to connect using a security key. The security key should be the router password but entering this gives a message to say the password is incorrect.

I have uninstalled and then installed without success.

If I type 12345678 as the security key, I can print wirelessly but this disconnects the internet so I have to log on again after printing. This then disconnects the printer.

Any ideas?

Welcome to HP Forums, 

This is a great place to get support, find answers and tips, 

Thank you for posting your query, I'll be more than glad to help you out 🙂 

It looks like you are using Wifi direct, and If yes, then the internet will automatically cut off when you use it. 🙂

In this case, I recommend you delete the driver and root level and retry with the computer which has this issue with the printer, follow the steps below: 

1)In Windows, search for and open Programs and features 

2) Select your HP Printer 

3) Select Uninstall 

4) In Windows, search for and open Devices and printers 

5) In the Devices and Printers windows look for your HP printer. If you see it listed right-click on it and choose ‘Delete’ or ‘Remove Device’ 

6) Open up the run command with the “Windows key + R” key combo. 

7) Type printui.exe /s and click Ok. (Note: there is a space in between “printui.exe” and “/s”) 

😎 Click on the “Drivers” tab 

9) Look for HP Printer driver. If you see it Click on it and click Remove at the bottom 

10) Select Ok 

11) Select Apply and Ok on the Print Server Properties windows 

12) Close Devices and Printers 

Once done, follow this link do a quick search with the product number, select the right operating system, and install the full feature driver software. 🙂
