Ok, this might either be a bug or me being silly.
I have a MeLe mini pc (all working fine) running SM v1.7.8 and I have added a USB WiFi dongle (also working fine).

Here's where I either don't understand or it's not showing correctly.
As you can see in the below screenshots, the HotSpot is set to "Internal WiFi", however this is incorrectly reported.


Stellarmate wlan1 with IP 10.42.0.1


home network with IP 192.168.2.160

Looking at the hardware with the following command lshw -C network
we can see that the actual internal interface of the MeLE is wlan0 (capabilities: ethernet physical wireless), while the USB dongle is wlan1

My question is why the StellarMate Tools reporting the wrong information? It should be swapped.

Yes that is wrong, it should have been wlan0. Can you please try to do a network reset then restart StellarMate to see if it fixes the issue?
