[SOLVED] Trouble Connecting to the internet

Hi, i'm trying to install arch linux on my PC with the intention of dual booting or switching entirely. Todo this i used rufus to create a USB bootable iso of of archlinux-2025.02.01-x86_64 however i faced issues at attempting to establish connection to my router. I have both a physical wifi module hooked directly into my motherboard aswell as an ethernet cable. Both work fine on my current windows installation. But on the arch bootable i cannot establish any internet connection.

I tried to follow various other people who had similar issues as me, but i didn't find anything that worked in my case. Here are some of the commands i ran and their CLI response
lspci -k. returning a bunch of information not related to wifi.

iwctl device list & ip link show both yield nothing of value. It's as if i have no devices physically connected, which wouldn't be the case otherwise windows wouldn't work.

Is there anymore information you would need to know?

Re: [SOLVED] Trouble Connecting to the internet

these 2 commands should give you the info you need:

lspci -k|grep -i -A 3 "eth\|communication\|network"
dmesg|grep -i "eth\|net"

Did you use dd mode?

What is your hardware, exactly?

Re: [SOLVED] Trouble Connecting to the internet

these 2 commands should give you the info you need:

lspci -k|grep -i -A 3 "eth\|communication\|network"
dmesg|grep -i "eth\|net"

Your commands did filter the list down to something readable.
Here are the results lspci -k|grep & dmesg|grep it shows the 2 network devices i described initially.
However i dont know what do do know as these 2 commands only show my network devices. How would i go about establishing an internet connection given this information?

dhcpcd

Sadly this didn't work i got the response "no valid interfaces found"

Did you use dd mode?

i didn't explicitly specify anything. I uploaded the iso to rufus and ran it with default settings.

Re: [SOLVED] Trouble Connecting to the internet

Your ethernet card should be supported by kernel 6.14: https://www.phoronix.com/news/Realtek-R … ev-B-Linux

I seem to remember that mt7925e being a bit of a bastard in other threads as well. I'll leave the searching to you, looks like you could do with the practice

Re: [SOLVED] Trouble Connecting to the internet

Ok after some time practicing i found the error. running

dmesg | grep mt7925e

lists the error "driver own failed" among others. This errors comes when linux can't take ownership of the driver, this is because windows is very possessive of my network driver. rebooting and powering off it not enough.
You need to completely shutdown the PC pull the plug wait 1 minute plug back in and you are golden, (you might even need to remove cmos battery if need be).

Doing that makes the driver show up on my device list and i can connect to the internet and continue normal arch installation
