Can't print over wired Network on MF656Cdw

I had my MF656Cdw for about a month on WiFi network. I upgraded to Eero 6+ mesh network and this printer no longer able to connect (or even see) this new WiFi network (I even tried manual connection by entering AP name).
So I connected it via CAT5e to the router/switch. I tried both static and dynamic IP4 addresses. I can ping the printer, I can access it's Remot UI, but I can't print to it at all. From any device on the network (i.e. no Airprint, no windows). What am I doing wrong?

If you installed the printer for WiFi connection you probably need to reinstall it for it to connect by wire. Completely uninstall it first.

Eero Mesh comes with WPA3 security enabled by default. I suggest you do 2 things.

1. Use separate SSID names for the 2.4 and 5Ghz networkd

and

2. Enable WPA2 on the 2.4Ghz broadcast in addition to WPA3.

Now rescan and your printer should likely see and connect to the new 2.4Ghz network.

Thanks guys! I got it working for now. Looks like DNS setting was wrong. After I fixed it I was able to start printing over network. About an hour later AirPrint started to work too on it's own. For now I'll leave it hardwired. My Eero doesn't have WPA3 enabled btw. Also with my previous WiFi cable modem/router (Altice) this printer also could not see AP name, but I was able to enter it manually. Really is a shame that Wireless firmware is so out of date. I'll see if there's an update available...
