HP Officejet 6820 - can't connect to WiFi (No Filtering)

HP Recommended
HP Officejet 6820
Microsoft Windows 10 (64-bit)



I'm having a problem to connect my HP Officejet 6820 to the internet. It worked just fine for about 2 years until it suddenly decided to not connect to the internet anymore. Nothing has changed in the set-up.


When I printed the WiFi test it told me that the filtering of MAC-adresses possibly could be enabled in my router. The filtering of MAC-adresses is disabled (I dubble-checked). I started searching the web and came across some posts on this forum with people experiencing the same trouble I have. Although there are some solutions, non of them work for me.


Some Specs:

printer: HP Officejet 6820

The modem brand: ZTE

The modem model: H369A

Age mode: 2 years


I will try to enlist all the things I already tried:

- Reset WiFi-settings on printer

- Reset printer to factory settings

- delete and re-install drivers printer

- Restart modem

- Reset modem to factory settings

- Add mac-adres of printer to the "enabled MAC-adresses list" of the modem, which ofcourse didn't make a difference because the filtering of mac-adresses is disabled...


Someone who can give me some new ideas or a solution?


Many thanks!!

@jetipo, Welcome to HP Support Community!


I see that you are unable to connect the printer to the network and I appreciate your time and efforts in trying to resolve the issue.


Since you have already tried all the steps, here are a few things you can try in addition to it-


Reset the router password and try connecting the printer.

If you still have issues, reset the router and try again.


And finally, we can try a complete reset on the printer. The reset instructions are specific for your printer and performing those steps on a different printer may brick the device. 

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset, and re-initialize the printer. 


In order to access your private messages, click the private message icon on the upper right corner of your HP Forums profile, next to your profile Name or simply click on this link.


Hope this helps!
