Does Deco support separate 2.4GHz and 5GHz SSIDs?
Deco supports disabling 2.4GHz and 5GHz separately under the Main/Guest/IOT networks.
As for separate SSIDs over 2.4GHz and 5GHz, it might not be completed via a single network, But you could set the Main Network to 5GHz only, and then create a different SSID for the 2.4 GHz only IOT network.
“One Network” is widespread in Mesh networks in order to enjoy seamless roaming, which is different from non-mesh traditional routers that require you to connect to the band you want manually. So we tend to remain one SSID per network, and Deco keeps its network simple by automatically choosing the band that gives you the best wireless roaming experience. It uses the same name for both the 2.4ghz and 5ghz bands under the same network. Both radio bands are active simultaneously. If the device is only compatible with 2.4 GHz, then it won't try to connect to 5 GHz. And if it supports both, it will connect to only one radio band at any given time. Based on the device's capabilities, the Band Steering feature of Deco will attempt to guide your connected devices to the band with the best performance.
So if you want separate SSIDs over 2.4 GHz and 5GHz Wi-Fi here is what you could do:
- Turn off 2.4 GHz under the Main Network.
- Enable the IOT network with a different SSID under 2.4 GHz only.

My post wasn't aimed at you, it was automatically added by their "voting" system. Now deleted.
I was just pointing out to TP-Link again the madness of going to the trouble of creating a post highligting the issues with a single SSID, receiving 9 pages of complaints about that lack of functionality over 18 months & still choosing not to address it.

We need separate SSID's to achieve the full speed of 1gb broadband, while 24ghz and 5ghz is mixed the max speed is 450Mbps
@Woody999000, et al.,
To fix this, follow these steps (make sure you're already connected to the Wi-Fi network on the respective device):
1. Launch the Deco app
2. Go to your Wi-Fi network
3. Click on "Online Clients"
4. Click on desired device, e.g. laptop
5. Click on "Connection Preference"
6. Click on "Preferred Wi-Fi Band", select 2.4, 5 or 6 GHz, click "Save" in the top right
7. Repeat steps 3-6 for all other devices

Hi, are you still having this issue now? You could try to restart the whole Deco system once to see whether it helped.
If you went to WLAN settings on the iPhone 14, are you able to manually reconnect to Deco 5 GHz-only Wi-Fi?
Thank you very much and wait for your reply.

If I buy the X75 system, would I be able to setup a 2.4ghz network first to assign all my smart lights (strict 2.4g only, mixed network doesn't connect), set all of these to 2.4G only and later convert the network to mixed 2.4/5/6G after setting up those lights?
