I have buildt my own IOT Hub like application. There are a multitude of ESP microcontrolers, which are sending sensor data to a server. This server is taking the data and storing it to a database.

So far this works well. However the Ip-Address of the wifi device should not change, as the Ip-Addresses where the ESPs send their data is programmed to the ESP decices.

Now I want to add internet to the server.

In some proximity to the server I have a wifi rooter, in between I have mounted an wifi range extender, to extend the network to my server.

The operating system I use is windows 10.
The two wifi range extender I use are: Netgear EX2700-100PES
 The first one is the access point for the ESP microcointroller side.
 The second one acts purely as an range extender for my internet rooter.
I have two external USB wifi antennas attached to the server.

Windows has recogniced the two wifi devices correctly.

However when I connect to one of these devices, windows does automatically disconnect from the other device and I have no clue why.

Theoretically it should be possible to run both devices at the same time, as they are in principle two sepertate network adapters...

What am I doing wrong?
