Hi @ppanish,

Thanks for joining our community!

I'd like to help clear up some confusion regarding the correlation/causation of the message you're seeing in the Deco app.

There is no correlation between the message you're seeing and the difficulty you encountered acquiring Internet connectivity during setup. Since your Internet connection is from a cable provider, they likely employ MAC (Media Access Control) Binding on their modems. This is commonplace for cable ISPs, and what it essentially does is "bind" your modem to the MAC address of your router.

What likely happened in your case is very common when switching between routers with a cable ISP. Your modem was bound to the MAC of your old router and didn't recognize the different MAC address on the Deco X55, so it wouldn't provide Internet connectivity to the mesh system. When replacing a router with a cable ISP, it is highly recommended that common steps be performed to release and renew MAC Binding. There are multiple ways to do it, but the most common involves power cycling the modem and router in a specific order. In your case, it sounds like the modem just needed to be directly connected to the Deco (bypassing the bridge) in order to bind to it.

As for the message you're receiving in the Deco app, you may be receiving it for a couple of reasons.

1. By far, the most likely reason is because you're using Fast Ethernet (10/100) interfaces in your existing system. Since the Deco's Gigabit Ethernet port is rated for up to 1000Mbps, the app may simply be notifying you that it is not running at its full potential due to the lower link speed negotiation. In this case, you can simply ignore the message since you are using existing 10/100 interfaces.

2. Much less likely: The message may be displayed in error. However, if you are not experiencing reductions in bandwidth (e.g., below the 10/100 limitations of your existing interfaces), then you can also ignore the message.
