Use nmcli connection show -active to show only current connections. ![]() to see Wi-Fi networks you have connected to in the past). Use nmcli connection show to show the human-readable name, UUID, and interface of all previously configured network connections (e.g. See the DEVICE MANAGEMENT COMMANDS section of man nmcli for more information. Use nmcli device show for more detailed information than nmcli device status. # Example output of `nmcli device status` Here is an example output for an active wireless connection Use nmcli general status to show general NetworkManager status. Here are a few basic commands to help you check your network status when using NetworkManager. Solution: use password 'foo!bar' or password 'foo$bar' instead. Special characters: you may want to place in literal (single) quotes, as in the above example, to ensure password with special characters are interpreted literally.Įxample problem: something like password foo!bar or password foo$bar would cause problems with history or variable expansion, assuming the passwords contain the literal characters ! and $. ![]() Nmcli device wifi connect 'FooBarNetwork' Nmcli device wifi connect 'M圜oolNetwork' password 'my_secure_password' # Unsecured networks don't need a password Nmcli device wifi connect password # Example: connecting to M圜oolNetwork ![]() # Specify network SSID and password (for secured networks) Wi-Fiįirst enable Wi-Fi and list available wireless networks: Your mileage may vary, of course, but Ethernet network connections have always worked automatically for me when using NetworkManager. You can verify your connection with nmcli general status or nmcli device status, which should show a connected state. EthernetĮthernet should be plug and play (assuming rvice is enabled)-just plug a working Ethernet cable into your computer (potentially via a USB adapter) and NetworkManager should take care of the rest. You can unblock it with rfkill unblock wifi see man rfkill for more information.Ĭheck-in point: The ip link command lists both a wireless and Ethernet network interface (in addition to the loopback interface lo). If ip link shows a wireless interface, but its status shows status DOWN, your Wi-Fi might be blocked. Then consult ArchWiki: Network configuration/Wireless and the references therein to see if your network card should be using a different kernel driver. This falls beyond the scope of this guide-you will need to know the manufacturer and model of your wireless network card (use lspci -v (or lsusb -v if the wireless device is connected via USB) and search the output for “Network controller”) and what kernel driver is currently handling the network card device (use lspci -k or lsusb -k). If ip link does not show a wireless interface, your wireless network card probably requires a kernel driver that does not ship by default with Arch, and you will have to install this kernel driver and load the corresponding kernel module. In the above example lo is my loopback interface, enp0s31f6 is my Ethernet interface, and wlp4s0 is my wireless interface. Wired network interfaces are conventionally prefixed with en and wireless interfaces with wl, Disable currently running network daemons (if needed)Ģ: enp0s31f6 #.Use systemd-resolved for DNS resolution.Arch Wiki: Network Configuration has useful general networking information for Arch Linux.Also consider ArchWiki: NetworkManager, but the coverage of relevant topics is somewhat patchy at the time of writing. ![]()
