Which special driver version need to support be200 mlo features.

[vernon]

Good afternoon

I am using wifi7 network card be200 on Ubuntu24.04.But i can't find Mlo function of be200 work.

I use command "iw dev  interface_name info",but i can't see something like link0,link1.

But when I try with system win11 24h2,i input command "netsh wlan show interfaces",I can see link0 link1 these things.

what additional configuration is required to make mlo functions work on ubuntu?

Those are my device and driver infomation:

kernel:

Linux  6.8.0-39-generic

driver:iwlwifi

driverversion:6.8.0-39-generic

firmware:86.fb5c9aeb.0 gl-c0-fm-c0-86.uc

lspci:Intel Corporation Wi-Fi 7(802.11be) AX1775*/AX1790*/BE20*/BE401/BE1750* 2x2 (rev 1a)

After update the os version to 6.11 and update firmware,the mlo feature can work.

It is seems ok for your driverversion and firmware version,What's the version of your wpa_supplicant?It need to update to 2.12.In 2.12,wpa_supplicant just start to support wifi7

[Zack1991]

Then how to upgrade wpa supplicant from v2.10 to v2.12?

Hi Vernon,

How did you update the firmware on 6.11? Do you have the driver that can share with us?

[vernon]

For Linux,you can just update kernel,then the driver version will update too.For the firmware, you can download from kernel/git/iwlwifi/linux-firmware.git - iwlwifi linux-firmware tree - for linux-firmware,choose iwlwifi-gl-c0-fm-c0-90.ucode

Thank you.

MLO means Multi Link Operation,I just check by command iw dev interface_name info,then if you can see over one link,thats means mlo feature is enabled.
