Network Configuration

Try the following steps to reset the server’s internet connection:

Before Starting….

To see which file is connected to the internet, use the next command:

• Like this, you will know which file you should update exactly.

nmcli d        

Step #1

Connect to the wifi and check the GATEWAY IP (basically the router’s IP).

• You can check it by running the Windows terminal “cmd” and typing ipconfig.

You could also check this information by accessing the router directly:

• The user/pass are usually → admin/admin but you sure reference your router

Step #2

You will need to change the configurations of the network directly from a network settings-oriented file usually called “ifcfg-eth0”, “ens33”, or “eno1”. In the case of this server, it is “enp89s0”. These files will usually be located at /etc/sysconfig/network-scripts/. The command to access this server’s network settings is:

vi /etc/sysconfig/network-scripts/{your_internet_file}        

Below, you can see what it usually looks like:

• You can notice that the IPADDR, GATEWAY, and DNS1 are all “192.168.0.1” and “192.168.0.101”, changed them as shown below

Step #3

After editing the file, you must restart the network with the command next:

sudo systemctl restart network        

Right after restarting, do the next two checking measures. If the packages or the gateways are well set, the internet connection will be all setup.

ping 8.8.8.8        

route -n
