There are multiple ways to install the network depending on what you are looking for. Some exceptions are described here.

Wireless

Install the following packages: ifplugd wireless_tools wpa_supplicant wpa_actiond dialog

Linux uses now netctl instead of netcfg.

If your wireless adapter requires a firmware (as described in the above Establish an internet connection section and also here), install the package containing your firmware. For example zd1211-firmware.

For Intel n2200 series, install ipw2200-fw.

Then load the module for kernel.

echo ipw2200-fw >> /etc/modules-load.d/wificard.conf

Connect to the network with wifi-menu (optionally checking the interface name with ip link, but usually it’s wlan0), which will generate a profile file in /etc/network.d named after the SSID. There are also templates available in /etc/network.d/examples/ for manual configuration. This will also create a profile present in /etc/netctl.

wifi-menu $INTERFACE

You might need to look at iwconfig or “id addr show” to find what is the interface of the Wifi card. Enable the profile (with single profile).

netctl enable $PROFILE

Check status of connection.

systemctl status netctl@$INTERFACE.service`

ifconfig

This command is in package net-tools, but these days just rely on “ip” and be a native person.

rfkill

It may be possible that the wifi card is blocked by the kernel. To list all the systems that may be impacted it is possible to list them with this command:

$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
1: acer-wireless: Wireless LAN
Soft blocked: yes
Hard blocked: no

If the interface is soft blocked, it is possible to unblock it as follows

rfkill unblock wifi
rfkill unblock bluetooth

With Linux on a Thinkpad it could be possible that things are blocked, causing for example the interface to load appropriately at boot phase and making the network not to work from time to time.
