Error Message:Network netmask (prefix length) is not tuned correctly Home network is too wide

I have an eero router and a fing box.  The error message:  Network netmask (prefix length) is not tuned correctly.  Home network is too wide: 192.168....., up to 1024 devices.

Not sure what this means I need to do on my router settings, if anything.  Any assistance here would be most appreciated.  I am on hold with eero now and not sure how long it will take to speak to an agent...  Thank you!

    Hey @Nate_C
    The issue was resolved by the original poster reaching out their network provider. May I ask if you have been in touch with yours as of yet? If not, it would be a good place to start!
