Unfortunately, it’s not possible to add the W130 with the W121 Kit, as the W130 is a different model with a distinct configuration during onboarding.

Please note that the W21 uses Wi-Fi connection during onboarding, whereas the W30/31 models uses Bluetooth connection during onboarding.

To ensure full compatibility, I would recommend getting a W21 single pack, which can be seamlessly integrated with your existing W121 kit.

Hi Thank you for the response. 

Just to double confirm, I already have two W21 Devices (Main router) and Satellite Router. So I will be able to add the third W21 and all 3 will be compatible  ? 

Thanks again in advance 

Yes, ​@Balakc , with the existing W121 mesh, you can add one more W21 as a satellite to the system.

Note: The total system would consist of three routers, meaning you can add one main router and two satellites to the W21 series. This also applies to the mAX Plus W30 and mAX Pro W31 models.

Thank you so much for your response. appreciate it.
