I would like to install Arch Linux. In the first part of the installation, I need to connect to a wireless LAN network. But I don't know what my network's SSID is.

How can I find this out?

I'm guessing the real problem is that you don't know what a SSID is. It's the technical term for the network's name, i.e. the thing that shows up in a listing of available networks.

If you don't know what network you're supposed to connect to, you'll have to ask somebody at your location. If you have a WiFi router, it probably has its default SSID printed on a sticker somewhere on it.

As the Arch wiki explains, you can get a list of available networks with the command

iw dev wlan0 scan

(where wlan0 is whatever your wireless device is named).

It can be hard to find your wireless router if you have a hidden SSID.

You need to give your network manager a little help. Try this:

iwconfig wlan0 essid "myRouterName"

Then you can search for it:

Arch: wifi-menu Debian: iwlist wlan0 | grep "myRouterName"
