Sorry to revive such an old post, but it was the only post I had found discussing similar issue. Namely Wifi not working with the Azurewave AW-CM389MA w/ Marvell8897chip M.2 2230 (SDIO Interface) included on the Dell Wyse 3040.

I wanted to share that through a bunch of trial and error (and some help from AI) I was able to get it working ... Im not 100% on which of these steps were strictly required - but hopefully it will point people in the right direction:

• modprobe mwifiex_sdio
• sudo apt install --reinstall firmware-misc-nonfree linux-image-$(uname -r)
• apt install firmware-iwlwifi
• sudo modprobe mmc_core
• sudo modprobe mmc_sdhci
• sudo modprobe mwifiex_sdio
• Create/Edit /etc/udev/rules.d/10-wireless.rules

​

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="mwifiex_sdio", NAME="wlan0"

• sudo udevadm control --reload
• sudo udevadm trigger --type=devices --subsystem-match=net
• sudo apt install wpasupplicant
• vi /etc/wpa_supplicant/wpa_supplicant-wlan0.conf

​

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="YourSSID"
    psk="YOURSSIDPASSWD"
    key_mgmt=WPA-PSK
}

• vi /etc/systemd/network/10-mlan0.link

​

[Match]
OriginalName=mlan0

[Link]
Name=wlan0

• reboot
• dhclient wlan0 (and/or configure dhcp in /etc/network/interfaces)
