Hello to everyone.

I'm connected to the internet using the internal wi-fi chipset and
driver (mwifiex_sdio)
embedded by default inside my ARM Chromebook. Since it does not work
well,in fact it generates a lot of errors,that are visible between the
dmesg messages :

[4.381282] mwifiex_sdio mmc2:0001:1: CMD_RESP: cmd 0x242 error, result=0x2
[4.383289] mwifiex_sdio mmc2:0001:1: mwifiex_process_cmdresp: cmd 0x242
failed during       initialization

I've decided to attach a different wi-fi adapter via USB,called :

[1971.271455] usb 3-1: new high-speed USB device number 3 using xhci-hcd
[1971.452435] usb 3-1: New USB device found, idVendor=2357, idProduct=0109,
bcdDevice= 2.00
[1971.452479] usb 3-1: New USB device strings: Mfr=1, Product=2,
SerialNumber=3
[1971.452512] usb 3-1: Product: 802.11n NIC
[1971.452543] usb 3-1: Manufacturer: Realtek
[1971.452573] usb 3-1: SerialNumber: 00e04c000001

Now,the point is : how can I "tell" Devuan 5 to use this adapter with its
driver ? (I don't know if the proper driver is installed,but anyway,I have
enabled the Realtek entry inside the kernel and I have installed the
firmware-linux-free.

Something is missing because as soon as Devuan starts,it automatically
chooses the marvell driver and it associates to the bssid automatically.
Where does it take the information to configure everything ? In addition,it
creates the mlan0 interface automatically,based on the Marvell adapter and
not on the Realtek adapter :

# ifconfig

lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
       inet 127.0.0.1  netmask 255.0.0.0
       inet6 ::1  prefixlen 128  scopeid 0x10<host>
       loop  txqueuelen 1000  (Local Loopback)

       TX packets 27  bytes 3569 (3.4 KiB)
       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

mlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
       inet 192.168.1.7  netmask 255.255.255.0  broadcast 192.168.1.255
       inet6 fe80::292f:4509:ac77:e093  prefixlen 64  scopeid 0x20<link>
       ether 60:21:c0:e9:44:63  txqueuelen 1000  (Ethernet)
       RX packets 1122  bytes 100742 (98.3 KiB)
       RX errors 0  dropped 0  overruns 0  frame 0
       TX packets 773  bytes 211774 (206.8 KiB)
       TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

There is no way to change the values I want through the network-manager
applications.

I tried to look for the file wpa_supplicant.conf but I didn't find it.
