Below are some simple things you can do to help secure your wifi network:
Login to your wireless router
Open Your internet browser and type in the address http://192.168.0.1 or http://192.168.1.1 (Most routers will have 192.168.0.1 or 192.168.1.1 as the default Router IP address).
1. Take Control of your Router Through a Unique Password:
If you don’t know your username and password don’t some of the default can be found with a simple Google search.
2. Change Your USER ID and Password Immediately:
Go to settings
Update your credentials
Like I said earlier the default information can easily be found doing a quick google search.
3. MAC Filtering:
Every Machine (PC/Laptop/Mobiles) has a unique identification number. That is known as Media Access Control (MAC) address. Through this control, you allow access to only selected devices. Any other device trying to access you network will be rejected by your router
4. Disable SSID:
I don’t see any need for broadcasting the name of your network, unless you want to promote your WiFi (in the cases of hotels/restaurants/lounges/malls etc). To disable broadcasts, go to WiFi Profiles, look for SSID Broadcast and select the Disable option.
(6) Enable Encryption:
There are two main types of encryption are available for this purpose: WiFi Protected Access (WPA) and Wired Equivalent Privacy (WEP). WPA 2 is the strongest encryption standard for wireless connections as of today.
