Nice sharing man! Just curious how you do the firmware update of your M9 plus? Now what bother me is that my ps5 is located 4M away from the main mesh but it couldn’t get a good speed, not even 100mbps using ps5 speed test🤣
For the printer part, sorry for not being able to provide solid solution, let’s hope someone here can solve the problem for you!

Hei man, this is the wireless speed?! If yes I really need to change my router already🤣
