How do I find out if my printer is compatible with WiFi router?

[Charles82]

We have just transferred over to fibre broadband but now the printer does not connect to the WiFi. It's a HP OfficeJet Pro 8620.  It's a brilliant machine that has worked well for me so I am very reluctant to buy a new one if I can get this to work.

I have tried the following:-

• usual WiFI network set up wizard on the printer itself - it sees the wifi router but won't connect
• hardwiring computer to printer and using HP Smart App to change the log in details
• using an ethernet cable from extender to printer but printer had a conniption about that
• HP Smart App on my phone
• switching off 6ghz and 6 ghz to see if it picks it up on the 2.4ghz

I have lost count of the number of times I have entered the password. 

Any thoughts on what else I can try?

As a last resort, how can I find out if the printer is compatible with the latest fibre routers or not?

@Charles82  2.5Ghz is the  same regardless of what router you have. 

 A wired connection should work 

Here’s the manual for that printer if you don’t have it   >HERE <. 

Via the app you need to make sure your device is also connected to 2.4Ghz

@Charles82   Have you used WPS on the printer and the app at the same time?

It worked for me after the manual approach did not work.
