Hello!

Would like to seek some advice.

Previous setup: Deco M9 plus (3 units) across 3 storeys

The family decided to go with another provider, which comes with EX510 as the main router. Unfortunately, the installer just came and replaced the router with the new EX510.

Thus, some dead spot has no internet access, which was served perfectly with the previous setup.

Questions:

1. Can I replace the new EX510 with the existing Deco M9 plus to connect to the ISP, and retain the setup to minimize the impact?

2. Is it redundant to use EX510 as the main router, and connect the other M9 plus?

Goal:

To establish a single SSID mesh network

Your recommendation & advice are welcome.

Thank you.

Nic
