WiFi problems with Eero mesh router

[johnschult]

Problem: New Canon TR8620 will not successfully perform WiFi setup. Neither mobile app or desktop app will configure WiFi correctly. Easy setup fails, manual setup does not prompt for password. Canon support offered no suggestions or solutions. 

Network: eero Pro 6

I had WPA3 enabled in Discover / eero Labs. I disabled it and performed WiFi setup again on the printer. Using the app again failed. I ended up having to do it manually and enter the password, but your mileage may vary. 

When doing the WiFi setup, only connect to one eero router. Select the MAC address for the closest eero. After that I was able to select my SSID, enter password, connect.

I found the answer on Reddit. I find it ridiculous that no other devices on my network have a problem, but a Canon printer in 2020 can't figure it out. Sigh 

I hope this helps someone else!

Exact same problem with the exact same printer. WPA3 prevent the printer from even asking for password.  Really wish I'd found your solution 3 hours ago! Would have saved me a lot of grief setting this up.
