Restarting the network of your AlmaLinux system can be a useful troubleshooting step, for example if you’re having problems connecting to the internet.
In this guide, we’ll show several methods for restarting the network on AlmaLinux, both from command line and GUI. You can apply these steps if you’ve recently migrated from CentOS to AlmaLinux or have performed a fresh AlmaLinux installation.
In this tutorial you will learn:
- How to restart the network in AlmaLinux via command line, through both NetworkManager and networkd
- How to restart the network in AlmaLinux through GNOME GUI

How to restart network via command line
To turn networking completely off and back on in AlmaLinux, we can use the following NetworkManager commands, which effectively restart the network for the operating system.
# nmcli networking off # nmcli networking on
We can also turn individual network interfaces off and back on. To see your currently configured interfaces, use the ip a command.
$ ip a
...
2: ens160: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 00:0c:29:14:b7:83 brd ff:ff:ff:ff:ff:ff
inet 192.168.137.132/24 brd 192.168.137.255 scope global dynamic noprefixroute ens160
valid_lft 1652sec preferred_lft 1652sec
inet6 fe80::5f00:9be8:e9e7:afff/64 scope link noprefixroute
valid_lft forever preferred_lft forever
In our case, the interface we want to reset is ens160. The following commands will take the interface down and put it back up, effectively restarting it.
# ifdown ens160 Connection 'ens160' successfully deactivated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/5)
And then put it back up:
# ifup ens160 Connection successfully activated (D-Bus active path: /org/freedesktop/NetworkManager/ActiveConnection/6)
One last way to reset a network interface in AlmaLinux is with the ip link commands, which work through networkd.
# sudo ip link set ens160 down # sudo ip link set ens160 up
How to restart network via GUI
If you are running the default GNOME GUI on AlmaLinux, the simplest way to restart the network is to click on the top right settings area of the taskbar. Select your network interface you wish to reset, then click “Turn off.”
Click again to turn it back on.
Closing Thoughts
In this guide, we saw how to restart the network on AlmaLinux through command line methods and GUI. Any of these methods are effective at restarting the network, and you can use whichever is most convenient for you. This can be a helpful step when troubleshooting a network interface or internet connection. Since your network interfaces may be managed by either NetworkManager or networkd, we’ve included all applicable instructions in this article.
