WiFi problems (my pc is an asus vivobook 15 F1504ZA)

[Davidinzox000a9]

the wifi appears but does not show anything, even if the router is close to the pc, the pc hotspot does not work either and if I click show hidden networks like the button becomes gray but does not load anything. Then if I type "nmcli device"
in the terminal, it displays the one shown in the image.

In the photo everything is in Italian so to understand translate the image into English

@Davidinzox000a9 can you tell me which linux kernel version (uname -r) you are using (driver should be mt7902/mt7921). Can you give me the output of commands

uname -r
iwconfig wlo1
sudo dmesg | grep mt7921
sudo dmesg | grep wlo1

Besides, on Cachy-OS 6.18 my bluetooth device was working, but in this new kernel version it stopped.

@pmbfsa please check

dmesg | grep mt7921

as the driver now named mt7921. If it doesn't show means driver not loaded. If it shows some error than there is some problem of driver to connect to wifi

[OnlineLearningTutorials]

@pmbfsa please use latest firmware

[pmbfsa]

@OnlineLearningTutorials At first I didn't understand your command, but I read de README file again and I saw the topic 🔧 Firmwares used where you explained about the new firmware files.

So, I went there and executed the file install_firmware.sh

> cd mt7902_firmware/latest/
> sudo bash install_firmware.sh

Finally I reinstalled all the drivers by sudo bash fix_my_wifi.sh and now Wi-Fi is working.
For the first time I could connect to Wi-Fi by this computer, thanks ❤️

Unfortunatelly, my Bluetooth still dead 🫤

Listing my rf devices only WLAN is showing:

> rfkill list all
3: phy3: Wireless LAN
        Soft blocked: no
        Hard blocked: no

@OnlineLearningTutorials I've found new info here about the bluetooth.

I was searching for something wrong in the bluetooth part of the script file fix_my_wifi.sh and I found nothing. The modules btmtk.ko and btusb.ko were created and successfully copied to /lib/modules/mt7902_custom/.

Next, I found out that the modules were installed by the script file /usr/local/bin/mt7902-setup.sh, so I went there and tried each command manually. Here is the result:

/lib/modules/mt7902_custom
> rmmod btusb btmtk mt7921e mt7921_common mt792x_lib mt76_connac_lib mt76 2>/dev/null

> sudo rmmod btusb btmtk mt7921e mt7921_common mt792x_lib mt76_connac_lib mt76 2>/dev/null

> sudo modprobe cfg80211

> sudo modprobe mac80211

> sudo insmod /lib/modules/mt7902_custom/mt76.ko

> sudo insmod /lib/modules/mt7902_custom/mt76-connac-lib.ko

> sudo insmod /lib/modules/mt7902_custom/mt792x-lib.ko

> sudo insmod /lib/modules/mt7902_custom/mt7921-common.ko

> sudo insmod /lib/modules/mt7902_custom/mt7921e.ko

> sudo insmod /lib/modules/mt7902_custom/btmtk.ko
insmod: ERROR: could not insert module /lib/modules/mt7902_custom/btmtk.ko: Unknown symbol in module

> sudo insmod /lib/modules/mt7902_custom/btusb.ko
insmod: ERROR: could not insert module /lib/modules/mt7902_custom/btusb.ko: Unknown symbol in module

> sudo systemctl restart bluetooth

As you can see, the bluetooth modules setup didn't work here. Using the command sudo dmesg | tail after each error I've gotten these results:

[ 1303.952834] btusb: Unknown symbol btrtl_set_driver_name (err -2)

[ 1432.001223] btmtk: Unknown symbol hci_cmd_sync_cancel (err -2)

Do you have any idea of what is doing wrong here?

[pmbfsa]

@OnlineLearningTutorials Partial good news, I've found out what was wrong.

The setup script file /usr/local/bin/mt7902-setup.sh created by fix_my_wifi.sh has a little issue about dependencies when loading the modules btmtk.ko and btusb.ko.

The former depends on module bluetooth and the latter depends on btrtl, btintel and btbcm, these also depends on bluetooth. So, I changed the text that creates the setup script to load all dependencies before the custom bluetooth modules:

if [ -f /lib/modules/mt7902_custom/btmtk.ko ]; then
    # Load Bluetooth stack
    modprobe bluetooth
    modprobe btrtl
    modprobe btintel
    modprobe btbcm

    # Load custom MT7902 modules (Bluetooth)
    insmod /lib/modules/mt7902_custom/btmtk.ko
    insmod /lib/modules/mt7902_custom/btusb.ko

    systemctl restart bluetooth
fi

Now, bluetooth service is starting with the OS, as expected.

The bad news is that the bluetooth service isn't finding any bluetooth adapter. Because of this when I try to add a new device the service starts to search for a new device in an loop finding nothing.

On kernel 6.18 the bluetooth adapter was working and WiFi wasn't 😅. Then, all the bluetooth devices that I used before aren't showing anymore.
