The BE200 (recent upgrade) in my laptop is working fine, however it's very slow on 6Ghz / WiFi 7 and won't load the latest firmware.
I'm running Ubuntu 24.04.

I've downloaded the latest firmware from the git tree:

and updated the kernel:

6.17.12-061712-generic #202512121841 SMP PREEMPT_DYNAMIC Fri Dec 12 21:43:56 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux.

However, it won't load the newer firmware - even though it's looking for it.

The output of dmesg | egrep -i 'iwlwifi|be200|wlan' is:

How do I get it to load the latest firmware (anything higher than 98) ?

Hi OnlyTheTony,

Thank you for posting in our Community. This gives a clear picture of what’s happening with your Intel® Wi-Fi 7 BE200 320MHz adapter on Ubuntu 24.04. This behavior typically happens when firmware file does not match the driver’s expected format or version. Even if the file is present, the driver will reject it if the size or checksum is unexpected. Kernel / driver version is not fully compatible with the latest firmware. Intel drivers sometimes require a specific kernel or backport module to accept newer firmware. Firmware file is placed in the wrong directory or with incorrect permissions. The driver must be able to read it during init.

To address the issue of the Intel® Wi-Fi 7 BE200 not loading the latest firmware on Ubuntu, follow these recommended steps:

Download the correct firmware files from the firmware git tree.
Install the firmware manually using the following commands:

# sudo cp iwlwifi-* /lib/firmware/
# sudo modprobe iwlwifi

If issues persist, consider contacting your Linux distribution support for assistance with updating the firmware path configuration.

Have a nice day!

Thanks for getting back to me.

I replaced the .zst firmware files in /lib/firmware with the uncompressed .ucode files and it's now loading the most recently available version - 101.

[ 3.866445] iwlwifi 0000:2b:00.0: Detected Intel(R) Wi-Fi 7 BE200 320MHz [ 3.866881] iwlwifi 0000:2b:00.0: Direct firmware load for iwlwifi-gl-c0-fm-c0-102.ucode failed with error -2 [ 3.871711] iwlwifi 0000:2b:00.0: loaded firmware version 101.6ef20b19.0 gl-c0-fm-c0-101.ucode op_mode iwlmld

I also built wpa_supplicant v2.11 which is loading correctly but it still won't connect to 6Ghz - and on the rare occasions that it does it is painfully slow (500 - 600Mbit on 5Ghz but 40 - 50Mbit on 6Ghz).

Have I missed a stage?

Randy,

Thanks for your reply. Could you please provide a link to that firmware version as it's not on the current git tree.

Thanks.
