Assignment of one client to 5GHz and other client to 2.4 GHz

[albamu]

Many thx for your quick answer.

The easiest way is to set different SSIDs to both wireless interfaces (you may keep same PSK for both, but you can set them different as well). Then configure stations to connect to whichever you want them to … and make sure they don’t “remember” the other SSID so that they don’t connect to the other one if they get disconnected from the preferred one.

Different SSIDs is a way - but I cant get this way because e.g. I want to connect with my smartphone at 5GHz to one IoT at 2.4 GHz and this is not possible to connect with two different SSIDs.
I think but not know.

I had read this thread at the last minutes: http://forum.mikrotik.com/t/band-steering-priority-to-5ghz/151993/1
and have learnt it’s not possible at the moment. The devices do the decision.

@mkx

If separation on the wired part of your LAN is not your goal, then you just keep the rest of config as is now. If OTOH you’d like to separate both wireless networks and control communication of one subset of drvices, then you’d have to redesign your whole LAN.

I’m not sure that I can your comment translated correct - sorry.
The wired devices at 192.168.2.0/24 have no “contact” to the wireless devices connected to the cAP’s at 172.16.99.0/24

What is OTOH? Maybe IoT?
If so - yes I want to isolate all IoT at a separate Sub-Net - that’s my next step. And only connect from my smartphone at 172.16.99.0/24 allowed to the IoT at the new Sub-Net.
But at the moment I dont know how to to this.
Any hints for me please?
