My HP officejet pro 8600 will not connect to the router

[HiggsK]

I cannot get my printer to recognise my new router.

We recently installed fiber and have a new router. The printer connected perfectly wirelessly with the old router.

I have updated the software for the printer , I have done a factory reset, I have tried to enter the settings manually and still it says unable to connect. It recognises the router in the search for network but will not connect. My new router is a Murcusys  ac12. I have also checked all the settings on the router. it is both 2.4Ghz and 5.0Ghz compatible. Please someone advise this dumb dumb.

@HiggsK, Welcome to HP Support Community!

Replacing/reconnecting/changing your wireless router, try here.

* Reset your printer back to Network Defaults.  Then run the Wireless Setup Wizard to connect.  Both can be accessed from the front panel or computer.  If no front panel for configuration, you must use your Printer USB cable to connect.  You can also try the WPS method if your router/printer supports this only if the Wizard or Printer USB cable is not available.  Read your User Guide for info.

* Wireless printers only connect to the 2.4G band in your router.  The router must have the 2.4G SSID band enabled with a different SSID name than your 5.0G SSID band in your router.

* Set router to a fixed wireless channel like 1, 6 or 11, never ‘auto’.  Try channel 1 first then the others one at a time. 

* Make sure printer and router are at least 5 feet apart. 

Also, refer to the document HP Printers - No Connection after Router or Wi-Fi Settings Change
