Enable MediaTek USB Wifi Dongle

pilotnite — Mon, 12 Aug 2024 15:45:19 GMT

Hello All,

I’m trying to enable a MediaTek USB WiFi Dongle (Mediatek mt7921au) and have enabled the following in the defconfig:

CONFIG_WLAN=y
CONFIG_WLAN_VENDOR_MEDIATEK=y
CONFIG_MT76_CORE=y
CONFIG_MT7921U=y
CONFIG_MT7921_COMMON=y

When I plug in the USB dongle and run lsusb, I see the following:

root@localhost:~# lsusb
Bus 001 Device 002: ID 0e8d:7961 MediaTek Inc. Wireless_Device
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

However, I don’t see any WiFi interface in ip a or in nmcli.

Does anyone have any thoughts on what I might be missing? Any help would be highly appreciated.

Thank you!

Hi @pilotnite!

unfortunately we don´t have experience using that wifi module in our boards.

We recommend to use the wifi installed in the board.

Best Regards!

@Chavira

Thank you for your feedback.

Can you help me with onboard wifi? What are defconfig and linux-firmware (if any) needed?

The wireless driver supports wpa_supplicant, which is a WEP/WPA/WPA2/WPA3 encryption authenticated tool.

• Wi-Fi driver: supports NXP 88W8987-based modules with SDIO interface, NXP 88W9098-based modules with PCIe and SDIO interfaces, NXP 88W8997-based modules with PCIe and SDIO interfaces, NXP IW416- based modules with SDIO interface, NXP 88W8801-based modules with SDIO interface, and NXP IW612- based modules with SDIO interface.

• Firmware
The NXP release package already includes all NXP, Wi-Fi/Bluetooth firmware. It requires to accept NXP license.

To run Wi-Fi, execute the following commands first and follow common commands below:
• For the following steps, execute these commands using connman

# For all the Wi-Fi modules: modprobe moal mod_para=nxp/wifi_mod_para.conf $connmanctl connmanctl> enable wifi connmanctl> scan wifi connmanctl> services /* This should list of the network.
