MediaTek MT7915 Wi-Fi Card not working

Installing and Using OpenWrt
1

Hello,

I have purchased the MT7915e wifi card from asiarf.

I have installed the drivers that I though were the best fit for the module which are kmod-mt7915e

When booting there was no wifi and when checking the long this is what stood out.

Sat Jul 29 06:50:28 2023 daemon.notice netifd: radio0 (32662): Could not find PHY for device 'radio0'
Sat Jul 29 06:50:28 2023 daemon.notice netifd: Wireless device 'radio0' set retry=0
Sat Jul 29 06:50:28 2023 daemon.crit netifd: Wireless device 'radio0' setup failed, retry=0
Sat Jul 29 06:50:28 2023 daemon.notice netifd: radio0 (32722): WARNING: Variable 'data' does not exist or is not an array/object
Sat Jul 29 06:50:28 2023 daemon.notice netifd: radio0 (32722): Bug: PHY is undefined for device 'radio0'
Sat Jul 29 06:50:28 2023 daemon.notice netifd: Wireless device 'radio0' is now down

Could someone help me troubleshoot this issue?

you probably need kmod-mt7915-firmware. For my device, kmod-mt7915e is used in openwrt 22.03, whereas kmod-mt7915-firmware is used in newer snapshots and 23.05. Don't ask me why.

Hmm, that did not seem to work. I am on version 22.03.5
I do have all of the MT drivers installed, do you think that they would conflict is a way?
I can see the module when I do lspci, comes up as

0001:01:00.0 Unclassified device [0002]: MEDIATEK Corp. MT7915E 802.11ax PCI Express Wireless Network Adapter

You would need to reboot after installing the firmware. I'm sure you know that, but just figured I'd throw it out there.

You should only install the drivers you need. They /shouldn't/ interfere with each other, but it's a good precaution.

How is the device addressed in /etc/config/wireless? Are you using option phy or option path?

5

So I have uninstalled all of the drivers that are not needed, I kept the dependencies drivers.

It doesn't seem that I am using either, which do you recommend?

config wifi-device 'radio0'
        option type 'mac80211'
        option country 'US'
        option channel 'auto'


config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'OpenWrt'
        option encryption 'psk-mixed'
        option key '12345678'
6

Usually it gets auto-detected when you put the card in. I don't know if the fact you are missing the device address in your /etc/config/wireless is because of an issue loading the driver, or if the error with the driver is because there is no addressing for it in /etc/config/wireless

Try option phy phy0 to start, because that's the easiest. Figuring out the right path for option path for a PCIe device is a bit of an arcane art. If phy doesn't work, though, we'll try that.

7

So my wireless config file looks as followed:

config wifi-device 'radio0'
        option type 'mac80211'
        option country 'US'
        option channel 'auto'
        option phy 'phy0'


config wifi-iface 'default_radio0'
        option device 'radio0'
        option network 'lan'
        option mode 'ap'
        option ssid 'OpenWrt'
        option encryption 'psk-mixed'
        option key '12345678'

I also did a system reboot, and in my logs I still get the messages as stated in the original post.

8

Those errors are from netifd, not from the driver. Can you post your full dmesg? I would like to see the driver load messages.

Here are the full kernel logs.

Hmm I'm not sure but I do see this here:

Either I would assume this could indicate two things.

  1. intel driver forms as a place holder when the driver is unknown as fallback for generic intel drivers.

  2. or you got a concurent driver which OpenWrt seems to see as default.

When I look more up in the logs I do see some pci-e allocations and no errors, so I guess that loaded fine.

What does the normal log say after a fresh restart at the beginning?, Or if it was normal log what does kernel log say?

Normally the normal log sometimes also show interesting things like how the mt7915e firmware mounts or when it needs it, on 22.05.0-RC1 I had to install it which on prior versions I had not to.

11

Neither, it just means that the iwlwifi kmod package is installed (the package hooks into /etc/modules.d/ and will load the module unconditionally), not that the hardware is present (there would be much more log noise if it were). The module gets loaded, wastes a little RAM, but otherwise doesn't do anything, as it can't find supported hardware.

The good news is that the card is getting recognized on the PCI bus (0.718968 in the log)
The bad news is I'm not seeing any messages from the 7915 driver. I would expect to see:

Try:

  • lspci -v to see what the pci subsystem says about the device. The last line of output for the card should say "Kernel driver in use: mt7915e"
  • lsmod to check what kernel modules are loaded. You should have mac80211, mt76, mtk76_connac_lib, mt7915e
  • If the modules aren't being loaded, check /etc/modules.d and see if mt7915e is listed there.

So the modules (mt76, mtk76_connac_lib, mt7915e) are not listed in lsmod and they aren't listed /etc/modules.d. I built this image with them pre-installed and they are coming up as installed in my software tab.

14

Do you mean the system logs?

15

For some reason in the boot image the driver wasn't set to auto-load in /etc/modules.d. You can try to fix that with...
echo mt7915e > /etc/module.d/mt7915e
...and reboot

Or you can try to reinstall the driver:
opkg --force-reinstall install kmod-mt7915e

I'd try that in order. Should get you up and running.

16

This command returned:

/bin/ash: can't create /etc/module.d/mt7915e: nonexistent directory

UPDATE: But after I ran:

echo mt7915e > /etc/modules.d/mt7915e

And this command took, but the results during boot are the same as below.

And running force install returned:

Whoops, sorry. Typo when I replied.

Ok, so your installation is set to download packages, but the build you made has an incompatible kernel. The build you made should have placed all the kernel modules it compiled into the openwrt/bin/targets/[platform]/[target]/packages folder. Do you still have that build?

EDIT:

Oh, I missed that my first read. Ummmmm.... ok, there is something hinky with your build. Did you make some changes to the kernel config? You may need to make a new build.

18

I did not make any changes, I have no problem making a new build. Is there anything I should look for after running make kernel_menuconfig?

19

Running kernel_menuconfig at all is often not compatible with using out-of-tree kernel modules, which is what almost all OpenWrt's kernel modules are. It's especially bad for using kernel modules from the repository. What changes are you making in the kernel config?

20

I really wasn't changing anything. I am just wondering if there is something in there that may be causing an incompatibility with this module.
