Just buy a Brother. And set the network gateway to 0.0.0.0.
I did have a Wi-Fi problem that was a pain, but it's been good for months now. It usually works.
They used to have a firmware issue with Wifi. If you had your AP's setup so that they would scan and change channels to get on a less crowed channel the printer saved the channel number as part of the wifi config so the printer would no longer connect to the wifi if the channel was changed even though the rest of the config was valid.
The annoying solution (until a firmware update was issued eventually) was to just force your AP(s) to never jump channels.
That would explain it, and I didn't find that information on line. Everything looked fine in the config.
Still not updating firmware.
Yeah, I had to deploy these wifi printers to dozens of sites across the country. It's super fun to try to explain to a office worker how to plug a laptop into the ethernet port of the printer while you remote in and try to see why the printer is no longer connecting to the network.
I am fairly sure I posted that solution online when I was still hosting my own website(s). They have not been online for a few years now though.
The shit you have to figure out when you work in tech sigh.
