A default gateway is a router that is used to connect a computer to the internet. It is the default route that traffic will take when it is sent from the computer to the internet. In some cases, you may have more than one default gateway. This can happen if you have multiple routers connected to your network, or if you are using a virtual private network (VPN). If you have more than one default gateway, it can cause problems with your internet connection. For example, you may experience slow speeds or dropped connections. To fix this, you can delete one of the default gateways.
There are two ways to delete a default gateway on Ubuntu 20. The first way is to use the graphical user interface (GUI). To do this, open the Network Manager by clicking on the network icon in the top right corner of the screen. Then, click on the “Edit Connections” button. In the “Network Connections” window, select the connection that you want to delete the default gateway from. Then, click on the “Edit” button. In the “Edit Connection” window, click on the “IPv4 Settings” tab. Then, uncheck the “Automatic” checkbox and enter the IP address of the new default gateway.
