1. Introduction

In order to connect to TUC’s LAN you have to:

  1. The room must have a network socket
  2. A network card should be installed in your PC
  3. You need a UTP (Unshielded Twisted Pair) Category 5 cable, maximum length six meters.
  4. Fill out an online application

The Networking Center may provide you with the required cable.

In order to fill out the application, you need to know the MAC address. Go to Start->Run and type cmd. At the opening window, type ipconfig –all.


MAC address corresponds to the <<Physical Address>>.

When you fill out the application, the Center will provide with the necessary IP Address and Gateway in order to connect successfully.

2. Configuring the Connection

Go to Start -> Control Panel -> Network Connections

Right-click Local Area Connection icon and select Properties

Select Internet Protocol (TCP/IP) and press Properties


Choose Use the following IP address.

At the IP address field you type the “IP address” of your application. Subnet Mask field should be At the Default gateway field you type the given “Gateway”. At the Preferred DNS Server you type Press OK consecutively till open windows close. System will be updated and connect to the LAN.

3. Troubleshooting the connection

Check that the network card is ok. Go to Start -> Settings -> Network and Dial-Up Connections. Right-click Local Area Connection icon, then select Properties.

Press Configure Button.

Check Device Status Field. If the device is working properly check the settings. Go to Start->Run and type cmd. At the new window type ping

In case the returned message says No reply from, then there is a problem either at your settings or at the network socket.

Type the command ipconfig –all

Check the settings under Ethernet adapter Local Area Connection

Compare these settings with the settings that you were given from the Center. If there is an error, follow the steps in section 2. If settings are ok, use another UTP cable.

If the problem persists, connect another PC (that you know it connects properly) at the network socket. In case the second PC works, then either your Network card or the Operating System is to blame. Please contact your Administrator.
