@bjensen2 Glad it’s working for you now! People reported some wackiness with Arris cable modems. For example, this: https://community.netgear.com/t5/Nighthawk-Pro-Gaming-Routers/Fix-for-router-constantly-losing-connection-in-bridge-mode/td-p/1641529.
The above is for an Arris router in bridge mode, to which a simple modem is similar.
You are right the MAC address override did not take effect. We’ll look into that.
As the above link also shows, there doesn’t seem to be a clear rule about what MAC address the Arris modem likes. Sometimes, the modem just doesn’t work well with the router. And the technique to fix it is more like hit-and-miss.
