I bought an LBP236dw about a month ago, and I've noticed that at some point it seems to lose its network connectivity (plugged in via ethernet). Checking the status screen it says it still has its (correct) IP address, but none of my devices (two Windows desktops, a Windows laptop, a Linux laptop, and an iPad Pro) are able to communicate with it. The print spoolers act as though it's not there, its management page at http://<ipaddress> times out, it can't be pinged, etc.
The only workaround seems to be to turn it off and back on, at which point any print spools that are still holding onto jobs will send them off (and the printer's web management page works again, and it responds to pings), but this is a really frustrating and annoying workaround, and not at all what I expect of an office printer. I should just be able to hit "Print", then walk over and pick my jobs up off the printer.

The common points in this setup are the printer, the Ethernet cable and the router. I'm not familiar with the 236 as I have an MF743.
If it is possible, could the printer be factory defaulted?

Wow, I never saw this reply until just now🤦🏻
Yes, I tried factory defaulting, didn't fix anything.
Sometimes the printer wakes up from sleep when we send a print job, sometimes not. I don't have anything else on the network (wired or wireless) that has this problem, even past network printers (Brother, Oki) don't have this problem. The only difference is the printer.

Hmm...
I'd now reach out to Canon customer service to see if they can delve further into this as I'm just about out of ideas. 😐

Hi jessicaJ,
Please log into your router and assign a static (reserved) IP address for your printer. Power cycle the printer and ensure it is using the address you've assigned. Moving forward it will always receive this IP and you will be able to find it at this "destination".
Of course, Canon's support is always there as well.

Ah! Trying a static IP address! I missed that one. 🙁

I already have a reserved IP for the printer (I'm a huge nerd and have reserved addresses for all my "infrastructure" stuff - printers, NAS, home automation, WAP, ad nauseum)
The behavior is horribly inconsistent. Sometimes I'll send a print job after not printing anything for a week, and it cheerfully wakes up and spits out the job; other times I'll print something, it works, then go to print half an hour later and 😴 nothing, I have to power cycle the printer.
