CATO Socket port flapping with certain Spectrum modems

Hi everyone,

We would like to raise awareness of a recent issue, where the CATO Socket port may begin flapping when connected to specific Spectrum-provided modems.

While the root cause appears to be related to these modems and cannot be addressed on our side, replacing the modem is consistently proven to be an effective solution.

If you experience CATO socket port flapping and you are using Spectrum-provided modems. 
To resolve this issue, add  a Switch in between the CATO Socket and the Spectrum modem.
If the does not help, you can contact Spectrum support and requested a replacement modem, specifying that you need a different model due to compatibility issues.
Ask for either the Hitron ET2251 or EU2251, as both of these seems to have resolve this issue in real customer scenarios.

    If you can get Spectrum support to escalate the issue, and want specs from the Cato Hardware vendor, they will work with them; however, so far, they have had no luck with Spectrum. Cato wants to help, but they cannot undo the modem firmware changes\update.
