MT7902: hardware init failed ("Timeout for driver own", ASIC revision: 30003, Manjaro 6.15)

[rolliebae]

Hello!

I’m trying to get Wi-Fi working on my laptop with a MediaTek MT7902 chip under Manjaro Linux (kernel 6.15.7-1-MANJARO).
The driver builds and the module loads, but no Wi-Fi interface appears, and I see repeated errors in dmesg:

mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

System information:

• Distribution: Manjaro Linux
• Kernel version: 6.15.7-1-MANJARO
• Chip: MediaTek MT7902
  (lspci: 02:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:7902])
• ASIC revision: 30003 (from dmesg)
• Driver: OnlineLearningTutorials/mt7902_temp (latest commit, cloned with --depth 1)
• Firmware files are present in /lib/firmware/mediatek/:
  • WIFI_MT7902_patch_mcu_1_1_hdr.bin
  • WIFI_RAM_CODE_MT7902_1.bin

What I have tried:

• The module builds and loads without errors.
• Firmware files are unpacked and permissions are set.
• Tried different firmware versions (from Windows driver and linux-firmware).
• Tried different kernel versions (6.12, 6.15).
• Secure Boot is disabled.
• The chip is visible in lspci, but no Wi-Fi interface appears.
• No “firmware not found” errors in dmesg, only “Timeout for driver own” and “hardware init failed”.

dmesg output:

mt7902e 0000:02:00.0: enabling device (0000 -> 0002)
mt7902e 0000:02:00.0: disabling ASPM  L1
mt7902e 0000:02:00.0: ASIC revision: 30003
mt7902e 0000:02:00.0: Timeout for driver own
mt7902e 0000:02:00.0: hardware init failed

Questions:

• Is ASIC revision 30003 supported by this driver?
• Is there a working driver/firmware combination for MT7902 on Linux?
• Is there anything I can do to get Wi-Fi working on this chip?

Thank you for your work! I am ready to provide any additional logs or information if needed.

Welcome to the Manjaro community @rolliebae

A quick search of the forum reveals quite a few topics about the MT7902 wifi card: Search results for ‘MT7902’ - Manjaro Linux Forum

Unfortunately, as I mentioned in another reply a fortnight ago, it seems that there is no Linux support for the MediaTek 7902 card, and by the looks of it, MediaTek are in no rush to provide Linux support:

No. Unless Mediatek release a stable driver for Linux and someone creates a PKGBUILD and make it available from Arch User Repository, this will likely never happen. Your options are Get a replacement card (inside laptop) be sure to get a compatible version the number of antenna connections is important Get usb dongle a lot of usb wifi dongles exist the chipset used is paramount be sure it is compatible with Linux I own the following USB devices with kernel support - therefore wo…

Driver for MediaTek 7902 Wifi

Cheap laptops with Windows - socalled Winbooks - often means flaky wifi. See → MediaTek Wi-Fi 6E MT7902 Wireless Network Adapter See → How to get MediaTeK MT7902 support? [SOLVED] / Newbie Corner / Arch Linux Forums Use a USB wifi adapter or replace the card inside the laptop. SearX linux driver media tek 7902 wifi - sx.nix.dk

As suggested in the linked above topics, your best bet might be to get a WiFi dongle for use when running Linux on your laptop, or to replace the card inside the laptop with one that is Linux-compatible.

The Hardware for Linux site can be very useful for checking hardware compatibility - here’s the main report for your card: MediaTek Wi-Fi 6E MT7902 Wireless Network Adapter. Some other Hardware for Linux reports for that type of card can be found at: Results for id=‘14c3-7902’ (7)

That Mediatek wifi chip is not supported on Linux at all. If it is a m2 module you might need to open up your laptop to replace it. Else buy a usb wifi dongle which is supported by Linux.

From the github driver project you linked:

As mediatek wifi mt7902 wifi 6E works fine in windows 11, however linux does not implemented its driver as it is new and mediatek does not respond to making a driver for linux.

Mediatek has been very slow to get many of their WiFi drivers working properly in Linux of late. It could be a long wait before your present Mediatek WiFi adapter receives full Linux driver support. I would suggest purchasing an older USB Atheros N model WiFi adapter until your internal adapter’s driver is functioning properly. Buying a cheap older Atheros USB adapter based on the ath9k driver will give you rock solid Linux support. It will however be considerably slower than recent USB offerings, but it should be adequate for most internet activities, (unless you are a gamer).

You must be aware that there are frequently Linux driver support issues with many newer USB WiFi adapters. It can unfortunately take quite some time for manufacturers to work the bugs out of their newly released Linux WiFi drivers. There are newer USB WiFi adapters that work perfectly well with Linux, however there are also many that don’t. You must do your research very thoroughly when making any WiFi purchase intended for use with Linux. Otherwise you may end up with another dud on your hands, so buyer beware.
