If Wi-Fi isn't working in Ubuntu, click the gear icon at the top-right corner of the desktop, select System Settings, click the Software & Updates icon, and click the Additional Drivers tab. Ubuntu will scan your system's hardware and show any alternate drivers you can use.

Connect to a wired (Ethernet) network To set up most wired network connections, all you need to do is plug in a network cable. Connect to a VPN Set up a VPN connection to a local network over the internet.
Configuring the Private Network Interface
- Open the /etc/network/interfaces file.
- Check whether the line /etc/network/interfaces.
- Open the directory /etc/network/interfaces.
- Use vi to create the configuration file for the non-configured interface.
- To configure the private network, enter the following information:
Computers are connected in a network to exchange information or resources each other. Two or more computer connected through network media called computer network. Computer loaded with Linux Operating System can also be a part of network whether it is small or large network by its multitasking and multiuser natures.
Wireless Ethernet adapters allow you to connect any Ethernet-enabled device to a wireless network through ports, including USB, Ethernet and USB-C. Wireless Ethernet adapters can also be used to increase the speed of your computer system without having to worry about complicated software.
Enable The Ethernet Connection
- The first step is to open the control panel of your computer system.
- Search for the network and internet option and click on it.
- From the left tab, tap on “change the adapter settings”
- Scroll down to find your ethernet connection and right-click on it.
- Now, choose the enable button.
Try A Different Ethernet PortIt could be a problem where your ethernet port is not working. To figure out if you have a faulty router or modem try plugging the Ethernet cable in to a different port on the device. A router typically comes with multiple ethernet ports on them.
To connect a router to your computer with an Ethernet cable:
- Plug one end of an Ethernet cable into your modem.
- Plug the other end of the Ethernet cable into the Internet, Uplink, WAN or WLAN port on your router.
- Plug in your router and allow at least 2 to 3 minutes for it to light up.
Enabling adapter
- Open Settings.
- Click on Network & Security.
- Click on Status.
- Click on Change adapter options.
- Right-click the network adapter, and select the Enable option.
Ethernet is typically faster than a Wi-Fi connection, and it offers other advantages as well. A hardwired Ethernet cable connection is more secure and stable than Wi-Fi. You can test your computer's speeds on Wi-Fi versus an Ethernet connection easily.
You still need to plug in an Ethernet cable. Even if you're setting up a Wi-Fi network, you'll still need to plug your computer into the router with an Ethernet cable. But not to worry, the Ethernet cable is temporary, and once you get everything set up, you can unplug it.
If you've got working Wi-Fi but your wired ethernet connection is not working, the first thing to do is turn off the Wi-Fi. If Wi-Fi is disabled and you're still not getting a network connection, make sure that ethernet is enabled in the same Network and Internet Settings section. Find the right network.
Ubuntu / Debian
- Use the following command to restart the server networking service. # sudo /etc/init.d/networking restart or # sudo /etc/init.d/networking stop # sudo /etc/init.d/networking start else # sudo systemctl restart networking.
- Once this done, use the following command to check the server network status.
To change your IP address on Linux, use the “ifconfig” command followed by the name of your network interface and the new IP address to be changed on your computer. To assign the subnet mask, you can either add a “netmask” clause followed by the subnet mask or use the CIDR notation directly.
The following commands will get you the private IP address of your interfaces:
- ifconfig -a.
- ip addr (ip a)
- hostname -I | awk '{print $1}'
- ip route get 1.2.
- (Fedora) Wifi-Settings→ click the setting icon next to the Wifi name that you are connected to → Ipv4 and Ipv6 both can be seen.
- nmcli -p device show.
Enabling SSH on Ubuntu
- Open your terminal either by using the Ctrl+Alt+T keyboard shortcut or by clicking on the terminal icon and install the openssh-server package by typing: sudo apt update sudo apt install openssh-server.
- Once the installation is completed, the SSH service will start automatically.
How to Manually Set Your IP in Linux (including ip/netplan)
- Set Your IP Address. ifconfig eth0 192.168.1.5 netmask 255.255.255.0 up. Masscan Examples: From Installation to Everyday Use.
- Set Your Default Gateway. route add default gw 192.168.1.1.
- Set Your DNS Server. Yes, 1.1. 1.1 is a real DNS resolver by CloudFlare.
Ubuntu Desktop
- Click on the top right network icon and select settings of the network interface you wish to configure to use a static IP address on Ubuntu.
- Click on the settings icon to start IP address configuration.
- Select IPv4 tab.
- Select manual and enter your desired IP address, netmask, gateway and DNS settings.
eth0 is the first Ethernet interface. (Additional Ethernet interfaces would be named eth1, eth2, etc.) This type of interface is usually a NIC connected to the network by a category 5 cable. lo is the loopback interface. This is a special network interface that the system uses to communicate with itself.
Checking the host configuration with netstat. Apart from the ip command for displaying the network configuration, there's the common netstat command which has a lot of options and is generally useful on any UNIX system. This is a typical client machine in an IP network. It only has one network device, eth0.
Check os version in Linux
- Open the terminal application (bash shell)
- For remote server login using the ssh: ssh user@server-name.
- Type any one of the following command to find os name and version in Linux: cat /etc/os-release. lsb_release -a. hostnamectl.
- Type the following command to find Linux kernel version: uname -r.
You can disable specific LAN ports by using the VLAN feature. From there, you can select which LAN ports should be active and which should not.
