Hi MikeP1. Question. Before the upgrade, did you have a router from Telus that looked like this?
If it was, the newer Telus Wifi Hub has different wireless settings. I know the EcoTank printers prefer wifi that has separated 2.4GHz and 5GHz wireless networks and the older T3200 did have a setting for those.
The Wifi Hub doesn't have a setting to separate the two networks so it has a tendency to switch between the frequencies depending on how the connected devices are performing. That can cause a brief drop in connection for connected devices that includes PCs and printers. Some devices are slow to realize the frequency change and take time to reconnect which is why it takes your computer and printer several minutes to find each other again. This frequency change can also affect your Minecraft sessions if one or both PCs are on wireless. Connecting the PCs to a switch should solve their connectivity issue to each other but it won't address the printer.
One option for your printer, if you don't want to wait the several minutes for it to reconnect, is if it's located close to your PC, you could always connect it to the PC with a USB cable. Alternately the EcoTank printer does have a way to directly connect your PC through a dedicated wifi network on the printer but that may be more of a hassle to use as you'd have to swtich back and forth between it and your Wifi Hub.
The Telus Wifi Hub does not have settings for the USB port on it to be used as a print server.
