Network Configuration

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

It covers both wired (Ethernet) and wireless (Wi-Fi) setups.

1. See if the device shows up

Run:

ip link

2. Bring up the link manually

For wired:

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

For wireless:

sudo ip link set wlp2s0 up

3. If using Wi-Fi

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

4. Verify internet

ping -c 3 archlinux.org

5. If no NIC shows up

That usually means:

Missing driver module in mkinitcpio.conf or packages list (e.g. r8168, iwlwifi).

Sometimes needs firmware (linux-firmware should cover most cases — can add it in packages.x86_64/packages.aarch64).

6. LnOS @ UTA

If all else fails for UTA students I recommend checking UTA OIT WiFi guidelines to connect to WiFi internet: https://oit.uta.edu/services/wireless-network/
