i have installed parrot os on my asus rog g15 2022 model which comes with MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter.wifi is working properly but bluetooth is crashing every time. i tried updating bluez and blueman but both on latest update.parrot os is also up to date.

I assume the Wi-Fi [which is also the Bluetooth] is a RTL 88*** series you need the exact driver for the wi-fi [there are about 6 different ones I know of]

if you run from a terminal inxi -Nn it will give you the exact chipset including the all important suffixes.

ok i let me check …

Network:
Device-1: MEDIATEK MT7922 802.11ax PCI Express Wireless Network Adapter
driver: mt7921e
IF: wlo1 state: up mac: 10:6f:d9:33:37:1d
Device-2: Realtek RTL8125 2.5GbE driver: r8169
IF: enp3s0 state: down mac: 50:eb:f6:d2:74:b0

5

I am not over familiar with this one, but it appears to have the wrong driver, I think it should be the r8168 driver

6

Device-2: Realtek RTL8125 2.5GbE driver: r8169

thats his Ethernet adapter Brian…

Device-1: MEDIATEK MT7922 802.11ax PCI Express Wireless Network Adapter
driver: mt7921e

thats his WiFi and he’s already using the latest in kernel liniux driver for that chipset…

8

i think thats ethernet controller

9

ok so why my bluetooth is not working ?

10

i hope this output may also help :

i also found that brickwizard brian has also faced similar thread on ubuntu forum on www.linux.org. in the 2 page of that thread people are claiming that this problem can be fixed just my holding power button for 60seconds. i tried it once but didn’t work.

12

should i also provide dmesg output ?

guys as you can see the fireware cant load and look at this :

were is that fireware in this output …nope

15

that only works on some makes, but is a good stand by to try, [but thanks for looking in]

at this point, i would normally suggest uninstalling what MediaTek drivers you have and re-installing from here…config_mt7921e - kernelconfig.io, but you will need to upgrade to Kernel 6.2.6 or higher as well

my wifi is working normal but my bluetooth is not.i have found that there was a file named BT_RAM_CODE_MT7922_1_1_hdr.bin was missing from /lib/firmware/mediatek/ but kernel was asking in log and failing to load as its not availabe so i downloaded and puted in that folder but it didn’t fixed it. when i ran hciconfig -a it shows there is no mac and device is down,init,running as before download file it used to show down only.so i try to hciconfig hci0 up then my terminal hangs.currently i have that file but i have removed from the destination.

i think the driver you are mentioning is already installed.if installing you given will fix my bluetooth then i would want to installed it.is it safe to update kernel of parrotos manually ?

Well it will definitely be a driver or firmware isuue, and as Brian’s link shows, the adapter is supported…

If you look at the firmware repo,
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek

There are several firmware images available;
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek/BT_RAM_CODE_MT7922_1_1_hdr.bin

This is the one its using from your output;
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin

and this also available;
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/mediatek/WIFI_RAM_CODE_MT7922_1.bin

Try the 2 seperate versions rather than the combined you have, it may help…
( you may have to blacklist this one, [WIFI_MT7922_patch_mcu_1_1_hdr.bin], should tell you how in Brians link)

One thing to note here, on Linux WiFi can always be a pain point, and if drivers don’t work as you expect, then you can always file a bug and hope it gets fixed.
With Open Source software, no one is being paid to write drivers, and typically they have to start by reverse engineer Windblows drivers and then get them working.

Or try compiling your own drivers and firmware as Brickwizard advised above.

Either way, we have helped as much as we can with this!

Your not actually compiling a whole kernel, just compiling a kernel module that gets pulled it at boot up time so the kernel can talk to your devices. From a driver point of view, they are fairly generic across several adapters from a manufactiurer, usually only differing in the needed firmware.

If you have added the needed firmware, and the drivers are installed, and it still doesn’t work, then compiling your own, on the machine you need them on, is always the best way to go, they will be built specifically for your kernel and your system!

It’s really not scary, or difficult, just out of your comfort zone the first time or 2 :slight_smile:
