    Default Learn how to make your home Internet network safer and avoiding unauthorised access

    We are all in the habit of chasing convenience, and quite naturally so. Wired Internet connections are old world, and wireless Internet has almost become a necessity rather than a luxury. In this direction, we all have routers at our home so that we can enjoy wireless Internet on all our smartphones and tablets. However, not many of us are really concerned about the security of the wireless network. True, we are not exchanging highly sensitive documents over the network, but then, security is a basic! Would you be hospitable to anybody using your Internet connection without your permission? If you answered in a NO, read on, as this tutorial will tell you how to secure your router and wireless connection.

    To begin, you’ll have to know the type of the Internet connection (PPPoE/DHCP/Static). You’ll know that there’s a network icon in the system tray. Right click on it and select ‘Open Network and Sharing Center.’ Look for the ‘Change Adapter Settings’ and right click on the adapter connected. Then, select Properties and double click on ‘Internet Protocol Version 4 (TCP/IPv4).’ Next, you have to note down the entries in the fields, like Gateway, Subnet Mask and IP. Also, you need to know the DNS settings, which can be found using the ‘Advanced’ button.

    Now, we move on to the next stage. Once your router is connected, you can configure it by opening a web browser and keying in ‘192.168.1.1’. This address will work most of the times; if it doesn’t, then refer to the device manual for the IP address. Then, enter the login credentials. Now, you are all set to make some administrative changes. The first change is to modify the admin password. To do this, click on ‘Administration’ and then ‘Management’. In the ‘Router Password’ field, enter the desired new password and re-confirm it. Save the new settings and login again, with the new password.
    Now, how to configure the Internet, or Wide Area Network (WAN) connection?

    You’ll see a ‘Setup | Basic setup’ option. Use it to change the WAN connection type, in accordance with the kind of connection you have. If the Internet connection has automatic IP, then you need to specify the connection type as ‘Automatic Configuration - DHCP’. Otherwise, switch to ‘Static IP’ and key in the setting details you noted down earlier. If you are a PPPoE user, then just pick the name from the drop down list and provide the necessary username and password, as given by the provider.

    If you wish to set a tab at the number of terminals that can establish connection to the Internet through the router, you can. Just locate the option here and fill in. Now, we go on to the important step of securing your network.
    Come back to ‘Wireless | Basic Wireless Settings’ and let the network mode remain default, and then give a name to the wireless network so that it is identifiable. Now, protect the connection using a password, and to do this, use the ‘Wireless Security’ option, and pick a security mode. WPA2 is a more secure option than WEP. Let the default encryption type remain, and then set the password (8 to 13 characters). Now, save these settings and again log in to the router.
    Now, on with the last part of the tutorial. Here, you will learn to enable the MAC filter. With this, you can restrict other terminals from accessing your network, or define as to which terminals get to access your network. As I explained in the first step, proceed to the ‘Change Adapter Settings’ option of your network and sharing center, then right click on wireless adapter and click on ‘Status’. Here, select ‘Details’ and note down the address given as ‘Physical Address.’ This is the MAC address.

    Good article. You can also refer to 'Wireless Security Primer - 1 & 2'. Links can be found in the sticky post in the 'Broadband How-to' section.
