Hi-

I have had the Deco AXE5400 Base plus two hubs for about a month.  Easy set-up and great speed throughout the home (using wired backhaul).

The pathway to Deco is: Comcast/Xfinity coax cable to Arris TM822G modem (just modem not a router).  Deco base plugged into modem.  Deco acts as the router, and is also  plugged into an unmanaged switch. Extension hubs are plugged into ethernet from switch.

Twice in the last month it has had all 3 Deco units go solid red with no internet even when the internet modem shows connection.  Even after power cycling modem and router, no internet.  Pressing the reset button on Deco units put them in setup mode, so the last time the only solution was to delete and then reinstall the network and Deco units.  Took about 45 minutes to get everything running again.

My readings of this forum and others is that the problem may be MAC binding by Comcast/Xfinity, and I see the process to completely power cycle the modem with the coax disconnected to clear the cache.  I also see the process for MAC cloning in the DECO app.

I ask these two questions about my next steps:

1. If I do the MAC clone process, will this ensure that the Deco network will be able to see the internet the next time there is a modem outage?

2. Or will I have to do this long inconvenient process each time the modem loses the internet connection?

When I am traveling, it is impossible for me to get the family left at home to perform such a complicated process.  I need a solution that will work going forward.

Thank you for any help anyone can offer.
