Product: Hp laserjet pro 400 mfp M425dw
Operating System: Microsoft Windows 10 (64-bit)

Hi there,

 

My printer updated to latest firmware for Hp laserjet Pro 400 mfp m425dw (Firmware version 20210202). Since then wifi can only connect to router if it is open (without password and security).

 

Previously it was working fine and connecting as well with 2018 firmware for Hp laserjet pro 400 series.

 

I need old firmware as I cant find on hp software and downloads at all.
