Thank you

Hello i have a question when the drivers for ALFA AWUS036AXM with chipset MT7921u is gonna be fix.
Thank you

I have the same problem with the AXML, if I don't update it, it works no problem... Except for it shows my wireless adapter, it just freezes whenever I try to use it

I did a quick check, it seems that for MT7921u, the two firmware files are mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin and mediatek/WIFI_RAM_CODE_MT7961_1.bin.

As we can see in upstream repo https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ those two files got updated on 2024-11-12. You can do a git checkout and check the history of those files. Maybe this new version fixes the issue?

Now, all we can do is wait for a new version Debian package firmware-nonfree to be released, it will include this new version. Once a new version is out in Debian, it should reach Kali after a few days.

There's a bug opened (not quite the same) at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1070717, plus a duplicate: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1076078

Hello i check this to files a there is in this locations
locate WIFI_MT7961_patch_mcu_1_2_hdr.bin
/usr/lib/firmware/mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin

locate WIFI_RAM_CODE_MT7961_1.bin
