A step-by-step on how to create a WiFi at home

Once you've applied the changes, open up a browser and go the web address of (in our example) the Cisco/Linksys interface by typing http://192.168.1.1 and using the account name "admin" and password "admin." Then you are all set to configure security and other settings.
Most router companies use the same default IP address, admin account, and passwords on all their routers. Your router's documentation will tell you the specific IP address and account login information.

3. Configure security and IP addressing
After you've accessed the router, the next order of business is getting the security, SSID and IP addressing settings right. Getting security right is a must, unless you want a neighbour stealing your bandwidth and possibly your data. IP addressing is important because these addresses are used for devices on your network to communicate with the router. You make all of these changes within the router's management interface. These settings are typically under the "Basic" settings of the interface. They may also be under "Security" or "Wireless Settings." Router interfaces vary, so if you can't find the settings to configure within the router’s interface pages when following the below steps, check with the router manufacturer. Okay, on with the steps:

Change the default administrator password. Some networking equipment forces you to do so once you've accessed the web-based interface, but many consumer routers don't. The settings for the admin password are usually under the "System" tab or page of the interface. You can just enter in a new password in the new password field.
Change the router's default SSID. The SSID is the broadcasted name of your wireless network. That's the name that shows up as the network's name when you scan for available networks. Use a unique name that your neighbours aren't using for their routers to avoid confusion.
Assign security. Newer routers may be set by default to automatically configure security by using WPS (Wi-Fi Protected Setup). Since the goal here is to have full control of your network, switch from "WPS" to "Manual." Once in manual mode, go into the router's wireless security page. There is no excuse, except in very limited circumstances when dealing with legacy technology, to not use WPA/WPA2. WPA security requires clients connecting to it to use a key or passphrase, which you create within the router's interface on the same page you set up security. Some routers allow you to enter a string of 64 hexadecimal digits which provides strong security, but most have you create an 8 to 63 letter passphrase. If you are creating a passphrase (or password) be sure to create a strong password that would be hard to guess. For further advice on generating stronger passwords, check out our article on making sure your passwords are up to scratch.
Set up IP addressing. For most networks, the router can be kept at its default DHCP setting. This means the router will dole out IP addresses to clients that connect to the n
