[SOLVED] Help with installation: no wireless network

Hi:

As I said in my previous topic, my new laptop has both an ethernet controller and a wireless one, and I can't get an internet connection with neither. This post is for the wireless card:

The wireless card seems to be supported out of the box by driver `mt7921e`, and I can actually make some progress on the https://wiki.archlinux.org/title/Networ … n/Wireless tutorial:

- `ip link set wlan0 up` : does not complain, no output
- `iw dev wlan0 scan`: correctly identifies networks, including one I have created, with no encryption
- `iw dev wlan0 connect "openwireless.org"` : does not complain, no output
- `iw dev wlan0 link`: `Not connected`
- `systemctl status dhcpcd`:

Re: [SOLVED] Help with installation: no wireless network

iwd is probably already operating the NIC?
Sure your SSID is "openwireless.org" and also sure it's unencrypted (no wpa, no wep)?
You'll have to establish a carrier (wifi-cable) before dhcpcd can use that connection.
Have you tried iwd/iwctl?

Alternatively see the tethering hint in your other thread.

Sounds really to the point: can you provide more information?

Not a lot of information about "carrier" and dhcpcd... actually, this topic is the first I get when I search for ·"carrier+wifi-cable+dhcpcd" :-D

Re: [SOLVED] Help with installation: no wireless network

ok, so yeah, tethering (which does not require a single command :-O ) allowed me to install using archinstall which ~will most likely take~ *actually took care of* installing and configuring networkmanager!

So thanks a lot, Seth, and have a nice day (or the equivalent in your timezone)!
