Trouble getting wireless working

Jan Weidner · 2022-10-18 21:44:46

I am trying to install arch on a new machine and I fail getting wlan to work. I am using a live usb stick. First I tried to find out if I have a driver installed:

lspci -vnn | grep Wireless -A 15
0d:00.0 Network controller [0280]: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter [14c3:0616]
	Subsystem: MEDIATEK Corp. MT7922 802.11ax PCI Express Wireless Network Adapter [14c3:0616]
	Flags: bus master, fast devsel, latency 0, IRQ 142, IOMMU group 21
	Memory at fc20300000 (64-bit, prefetchable) [size=1M]
	Memory at fc500000 (64-bit, non-prefetchable) [size=32K]
	Capabilities: [80] Express Endpoint, MSI 00
	Capabilities: [e0] MSI: Enable+ Count=1/32 Maskable+ 64bit+
	Capabilities: [f8] Power Management version 3
	Capabilities: [100] Vendor Specific Information: ID=1556 Rev=1 Len=008 <?>
	Capabilities: [108] Latency Tolerance Reporting
	Capabilities: [110] L1 PM Substates
	Capabilities: [200] Advanced Error Reporting
	Kernel driver in use: mt7921e
	Kernel modules: mt7921e, wl

So I think the driver is mt7921e and indeed installed? However it seems that something failed:

dmesg | grep mt7921e

Am I doing something wrong? What to try next?

Are you dual booting? If you don't shut down Windows fully, including disabling the default hibernation style shutdown, you can see things like this.

See https://wiki.archlinux.org/title/Networ … n/Wireless. You can search the hardware databases for yours to see which driver it needs and if you need firmware.

It looks from https://linux-hardware.org/?id=pci:14c3-0616-105b-e0cd as if it should be supported?

Mhh interesting. No windows or dual boot, but I did install an ubuntu before and the arch runs on live usb stick. Will try the hard shutdown thing.

Wow that did actually work for me, thanks a lot. Though the signal is pretty bad even if I move it right next to the hotspot. Same on ubuntu.
