Hi  @mhzinformatica 

I would recommend using an SDN Omada controller to manage the EAP units, it will bring you the following benefits:

1. The Omada cloud function requires an Omada controller;

2. Centralized management of the three EAP units, this is more convenient than logging webpage and configuring SSIDs three times;

3. fast roaming. You don't need a mesh network, Mesh is to wireless connecting different EAP units, while you have a switch to wired connecting all of them. What you need is fast reading. With this feature enabled, most clients can improve the fast roaming experience when moving among different APs;

4. As for the band config, fast roaming requires the SSIDs to be the same. So you can create an SSID combined with 2.4G and 5G;

5. Enable Band steering:  With this feature enabled, dual-band clients will be steered to the 5 GHz band when appropriate. The 5 GHz supports a larger number of non-overlapping channels and is less noisy, so this feature can improve your network performance.

Now that most of your clients are 2.4G, you can enable this feature to balance those 5 G-supported clients connected to 5G band.
