Network Configuration

This is a guide for connecting to the internet on LnOS Arch Edition.

NetworkManager command-line interface

nmcli connection add type wifi connection.id 'UTA WiFi' wifi.ssid 'UTA WiFi' \ 
wifi.mode infrastructure wifi-sec.key-mgmt wpa-eap 802-1x.eap peap 802-1x.identity "<your UTA username here>" \ 
802-1x.phase2-auth mschapv2 802-1x.password "<your UTA password here>"

Activate a Wi-Fi Connection with NetworkManager

nmtui

Check Network Devices

ip link

Enable Network Interface with DHCP

These are example network devices. Here wlp2s0 and enp3s0 would be the example network device interfaces from running the ip link command.

For wired:

sudo ip link set enp3s0 up
sudo dhclient enp3s0   # or sudo dhcpcd enp3s0

For wireless:

sudo ip link set wlp2s0 up

Wi-Fi Login Settings/Configurations

Check available networks:

nmcli dev wifi list

# or

nmcli device wifi list

Connect:

nmcli dev wifi connect "SSID" password "PASSWORD"

# or

nmcli device wifi connect "eduroam" \
    --ask

Check Internet Connection

ping -c 3 ping.archlinux.org

Network Card and Recommendations

If your system does not detect a network card (NIC), the most common reasons are:

  • Missing driver – The kernel may not include the correct driver for your hardware (e.g., Realtek r8168, Intel Wi-Fi iwlwifi).

  • Missing firmware – Some devices require additional firmware files. The linux-firmware package covers most cases.

    • For custom builds, ensure linux-firmware is listed under packages.x86_64 or packages.aarch64.

Recommendations:

  • Verify that your NIC is listed with ip link.

  • If no device appears, install or enable the appropriate driver and confirm linux-firmware is available.

  • NetworkManager Text User Interface with nmtui.

  • Manually adding WiFi connection (advanced).

  • Depending on the desktop environment you install they should have the network configuration settings at installation time.

LnOS @ UTA

If all else fails for UTA students we recommend contacting the club or contacting UTA OIT to connect to WiFi internet: https://oit.uta.edu/services/wireless-network/

Secure programming is important.
