I have just changed my old router to a new Archer AX3000.

Since then my internet works well and my devices are connected EXCEPT my wireless printer.

The Pinter is a Brother multi-function printer MFC9335CDW.

I am installing on MACOS 10.14 (Mojave) and have been using Mojave and the same printer for the past 3 years.

Since changing to the new router I cannot set up the printer. The Brother software set up cannot find the printer device.

Installing via USB connection is not an option as the router and printer are several meters apart.

Any ideas or advice will be greatly appreciated.

Thank you
