 |
|
Hey everyone. So I have a new Asus ROG X570-E motherboard that has a built-in MediaTek 7921e wifi module. Using kernel 5.14 or 5.15, I cannot get this card to activate in any way, shape or form.
I have dual-boot with Windows - surprise, it works fine there. Even though the box and branding says the wifi card is an Intel AX220, the driver it loads is a MT76 so that's what I've been going with.
| Code: | lspci -k:
06:00.0 Network controller: MEDIATEK Corp. Device 0608
Subsystem: MEDIATEK Corp. Device 0608 |
| Code: | lsusb:
Bus 003 Device 003: ID 0e8d:0608 MediaTek Inc. Wireless_Device |
| Code: | lshw -c network:
*-network UNCLAIMED
description: Network controller
product: MEDIATEK Corp.
vendor: MEDIATEK Corp.
physical id: 0
bus info: pci@0000:06:00.0
version: 00
width: 64 bits
clock: 33MHz
capabilities: pciexpress msi pm cap_list
configuration: latency=0
resources: memory:e0300000-e03fffff memory:e0400000-e0403fff memory:e0404000-e0404fff |
I can modprobe mt7921e and it loads up fine:
| Code: | mt7921e 90112 0
mt76_connac_lib 40960 1 mt7921e
mt76 90112 2 mt7921e,mt76_connac_lib
mac80211 1150976 3 mt76,mt7921e,mt76_connac_lib
cfg80211 1007616 4 mt76,mt7921e,mac80211,mt76_connac_lib |
MediaTek themselves say it's supported since kernel 5.12:
https://wireless.wiki.kernel.org/en/...ivers/mediatek),
Doing ip link only shows lo and onboard ethernet.
I just don't know what it is I'm missing to get this to work. I even found a post that Windows 10's fast startup can cause issues, so to go and delete the fast startup to get rid of the hibernation file, which I did (grabbing at straws) - didn't help. Also tried shutting the system down for a few hours.
I have the | Code: | | mediatek/WIFI_MT7961_patch_mcu_1_2_hdr.bin mediatek/WIFI_MT7922_patch_mcu_1_1_hdr.bin mediatek/WIFI_RAM_CODE_MT7961_1.bin mediatek/WIFI_RAM_CODE_MT7922_1.bin mediatek/mt7622_n9.bin mediatek/mt7622_rom_patch.bin |
firmware compiled in.
Modules built:
| Code: | undertaker /lib/modules/5.15.3-gentoo/kernel/drivers/net/wireless/mediatek # ls
mt76
undertaker /lib/modules/5.15.3-gentoo/kernel/drivers/net/wireless/mediatek # cd mt76
undertaker /lib/modules/5.15.3-gentoo/kernel/drivers/net/wireless/mediatek/mt76 # ls
mt76-connac-lib.ko mt76.ko mt7921
undertaker /lib/modules/5.15.3-gentoo/kernel/drivers/net/wireless/mediatek/mt76 # cd mt7921
undertaker /lib/modules/5.15.3-gentoo/kernel/drivers/net/wireless/mediatek/mt76/mt7921 # ls
mt7921e.ko |
System is fully up to date on ~amd64. Any one have any ideas? I don't even see anything in dmesg for this. The bluetooth component works fine.
Thanks!

I did search cateee.net kernel driver database for your device and now I doubt this Mediatek is your WiFi device. I think for some reason your real WiFi card is not showing in lspci. Possibly Windows is disabling it in the firmware. My 2¢.

I did think this too, but I've checked several times and it's most definitely enabled. I tried it with bluetooth disabled (also set in firmware) to see if that made a difference, it did not.

phil_r,
Its showing on both USB and PCI. That's possible if its in a M.2 slot as some keying allow a USB2 interface too.
Are you trying to use it as a PCIe or a USB device?
The wrong answer is both at the same time.
Show us all of and please.
Oh, put all of dmesg onto a pastebin too, after you are sure the module is loaded.

@Neddy...
I have two M.2 slots and they're both occupied with NVMe drives. The wifi is "integrated" onto the motherboard, but I don't know precisely how. I assume it's part of the main chipset.

Let me know if there's anything else you'd like to see. The more I look at this the more I start to think I simply have the wrong device, but based off what Windows loads and other research I've done I don't see what other device it could be.

phil_r,
| lspci: | 06:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:0608]
Subsystem: MEDIATEK Corp. Device [14c3:0608] |

Two different vendor IDs ... That's possible. I'm pretty sure that's two different devices now, both with the device ID 0608.
Ahhh ... you need this patch
Its dated 14-Nov-21.
Its not in the 5.15.0 kernel. That only has | Code: | static const struct pci_device_id mt7921_pci_device_table[] = {
{ PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x7961) },
{ },
};
|
so the patch won't even apply cleanly. Nor is it in 5.15.5.
How to fix it ... edit | Code: | | /usr/src/linux//drivers/net/wireless/mediatek/mt76/mt7921/pci.c |
At line 15, expect to see | Code: | | static const struct pci_device_id mt7921_pci_device_table[] = { |
Make that function read | Code: | static const struct pci_device_id mt7921_pci_device_table[] = {
{ PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x7961) },
{ PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x7922) },
{ PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x0608) },
{ PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x0616) },
{ },
};
|
The { PCI_DEVICE(PCI_VENDOR_ID_MEDIATEK, 0x0608) } line makes the driver bind to your device.
Now rebuild and reinstall the kernel. If you feel lucky, just rebuilding and reinstalling modules will do.

The adapter now shows up in Network Manager and can be configured, which obviously wasn't happening before.
You are THE MAN.
What a clusterf* that is... and I did get away with just rebuilding the modules then modprobe -r and modprobe them back. So that's sweet.
Hopefully that patch makes it into the kernel sometime soon.
Thanks again for figuring that out, I really, really appreciate it.

Does this actually work? My new computer has the Mediatek wifi controller in it, too. I patched (hand edited) the pci.c file, made a module. The module loads, but I still can't get the wireless interface to come up. I tried by hand with ifconfig, and with NetworkManager. Neither way does the wifi work.
Here are the lines in the log when I load the module:

You're going through what i went through. These two things did help for me though:
a) if you dual-boot with Windows, go into Windows and disable the fast-start nonsense (hibernataion, if you're old school). Make sure all that crap is turned off.
b) power down your system and actually pull the power cord for a moment.
I've had to do the power cord thing a couple of times but it does work (for me, at least). I'm putting it down to buggy firmware where some memory isn't being cleared on a soft reset so it doesn't initialize properly. Under Windows the drivers can handle it so it works fine, but under Linux that isn't there so it needs that extra helping hand.
I doubt it will ever be properly fixed because "it works with Windows" which as we know is the target market for these things. Us Linux folks just have to deal with it  This MediaTek wifi card reminds me of the old soft-modems of the early 2000's that worked fine in Windows 2000 and XP but were as dead as last year's calendar in Linux because of the drivers.

I've never had any problems with drivers in Linux, but in the past I've never used hardware that was anywhere near "cutting edge". I don't dual-boot, so thanks for the advice but I don't think I can use it. This is a desktop computer and I have ethernet, so I'm not so inconvenienced, but I would like to get it working some day. |

I'd still try the power cord trick, if I were you. What's the worst that can happen?

Tried it. Still didn't help. Thanks, anyway. |

I mentioned that I have a working ethernet connection on this computer so I don't feel the absence of wifi. However, I have recently discovered (yes, I'm a little slow) that the wifi card also handles bluetooth. I have a bluetooth speaker that I would like to use with the computer, so I do feel the absence of bluetooth.
The weird thing about this network card is that on the wifi side, it looks fine, it just refused to connect. And bluetooth startup proceeds normally, with no error messages:
| Code: | Feb 7 16:52:14 mu kernel: Bluetooth: Core ver 2.22

Any help?
Later edit:
I tried connecting to my phone as a wireless hotspot. The computer actually connected to the phone, but couldn't go any further. I tried pinging google, but that went nowhere. I tried pinging the numeric ip address for a couple of sites but it said "destination host unreachable". Very weird.
Latest edit: Bluetooth is working. Don't know why, but after I rebooted it was OK. |

Hmm. Now it works. (Still need to patch that pci.c file.) Maybe it was the new firmware that came out a couple of weeks ago.
