Nighthawk AC1750 not showing Canon MF644CDW in device list

Which router do you have? AC1750 is not a reliable guide to model number. Many devices come with an AC tag, but it is essentially a label that Netgear, and other brands, attach to hardware to describe wifi speeds.

Look at the label on the device for the model number.

What firmware is on the router?

The printer will not function unless I restart the router once the problem starts... more than once a week.

 

When I lose the ability to print:

1. The printer is not shown in Connected Devices

2. The printer shows in Access Control, and has an IP (a static IP that I set)

3. The printer's HMI shows it is connected to the static IP

4. I can still remote into the printer on the network

 

How is the printer connected to the network? Wifi? USB? Wired Ethernet?

Where did you "set" the printer's IP address? On the printers setup utility or on the router itself?

With USB printers on a Windows PC, and perhaps other configurations, the first place to look is in the "sleep" settings for the USB device.

The usual way to fix wifi printers is to find the printer maker's utility, the software that runs on your operating system. Then use that to connect the printer to the wifi.

The router just broadcasts wifi. It is then down to the printer to play ball. There isn't much that you can do on a router, beyond fixing it to a particular IP address, that affects what the printer gets up to.

Where possible, using the WPS feature can simplify things.
