Advice 1: How to remove a network connection

If your list of network connections there are those that are not used anymore and are simply no longer needed, you can delete it to avoid confusion. It doesn't take much time and does not require any special knowledge.
How to remove a network connection
Instruction
1
First of all click "start" then "control Panel". Find the tab "Network connections" and run it. If you have enabled the display mode category, then the tag will be in the section Network and connection to the Internet". Find it in the list of connections that you want to delete.
2
Deleting network connections there are some limitations. If unnecessary network connection is part of a network bridge, before deleting itself delete the network bridge (which can then re-create if you need). It is not necessary to remove independently of the virtual connection created by network programs (for example, adapters of the virtual private network created OpenVPN or Hamachi )- they are removed from those programs. Does not make sense to remove the network cards and adapters IEEE-1394 (Fire-Wire) - they will still be created by the operating system anew on the next reboot. Part of the described connections just can't be removed - the menu item "delete" is not available for them.

Then simply click the connection right click and select "delete"
Note
Be careful when deleting connections - even though it did not threaten any system malfunctions, but you may lose settings that have to be done over again, if you make a mistake and delete your connection.

Advice 2: How to create a new network connection

When you install the drivers for the network card, the network connection is created automatically. If it was installed incorrectly, or need to create a network connection in addition, for example, for Internet or connecting to another computer directly, you can do it manually.

Instruction
1
To do this, go to the operating system. If it is the operating system of Windows family, then go to "start menu", then select "control Panel", if not, select first "settings" and then "control Panel". If not that either, then you can go into "My computer" with the name in the right panel, system tasks, click on "control Panel".
2
Next go to "Network connections" panel and network tasks on the right, click "Create network connection". Opens the new connection wizard. Here choose the item you need. For example, to connect to the Internet, select "connect to Internet", click "Next" select "Set up my connection manually", then choose your connection type.
3
After this you need to make settings of the network connection. If this is an Internet connection, you must enter a user name and password. For LAN connection, you must register a minimum of network settings. Go to the network connection, select Internet Protocol (TCP\IP)", click "Properties", select "Use the following IP address", enter your parameters, e.g. ip address: 192.168.0.1, subnet mask: 255.255.0.0, default gateway: 192.168.0.2, below, enter the preferred DNS, if necessary.
4
For the Linux operating system enter "System" then choose "administrative tools", then "Network settings".
5
In Mac OS, the network connection is created as in Windows in the control panel.
6
Most often to connect to the network to create a network connection is not necessary. It is created when you enable the network card and install drivers. You will need to make the necessary settings.
