Is it located far from your router/access point? Seems to me that most routers just don't broadcast very far. I have a 5gz Deco mesh system in my two story house because the signal from my Arris router did not like going upstairs. I installed three devices and my pc is wired to the mesh device upstairs, and it is very fast. My printer is connected to my pc with a USB/printer cable, very stable and reliable and unlike 2.4 ghz wifi, which most Canon printers require, it is full duplex as are the 5gz mesh devices. The best way to keep a printing from dropping off wifi is to use a cable connection to your pc or laptop.
