Hello
I am trying to use the Edimax EW-7611ULB WIFI and Bluetooth USB adapter on my Ixora + Apalis board. At the moment I want to use the WIFI utility but I’ve run into a problem, the OS detects the device only as a bluetooth Adapter. This is the message I get when I connect the Adapter to the board:
[ 5751.533448] usb 1-1.3: new high-speed USB device number 8 using ci_hdrc

I’ve tried to follow the instructions here but connmanctl enable wifi doesn’t work and returns this:
Error wifi: Method "SetProperty" with signature "sv" on interface "net.connman.Technology" doesn't exist
These are the responses of the system to dmesg, lsusb and lsmod:

Also, when I was compiling the kernel, following this guide, I searched for the driver of this device (rtl8723bu) on nconfig, and I found this: “Device drivers → Network device support → wireless lan → Realtek devices” where other drivers from the same manufacturer are located but not this one. I activated an option here that reads: “Include support for untested Realtek 8xxx USB devices (EXPERIMENTAL)” to see if it worked but it didn’t.
I was wondering what could be the problem with this device. I find it very strange that it is recognized as a Bluetooth adapter but not as a WIFI one.
