Twenty years ago, it is very hard to imagine that Internet and E-mail was nothing like it is today. Even through accounts offered with the first Internet service providers were often difficult to use. Things have changed significantly when wired Internet tied to a desk. Now a day’s laptops and mobile devices give us access to friends via Wi-Fi, 3G and 4G technologies anywhere.

We use 3G and 4G data on our smartphones and Wi-Fi in the home, in coffee shops, in libraries and in airports. Faster and cheaper wireless routers and hotspots without the limiting bandwidth of cellular data helps turned into a convenient Wi-Fi zone.

We can install wireless routers ourselves or we can get them from Internet providers. Majority of the members have Wi-Fi routers in their homes now a day’s. The main problem is the routers cause interference when wireless signals are operating on the same frequency. Without proper security, someone could easily step onto your wireless network.

Understanding Your Wi-Fi Network

It is important to understand some basic computer networking on how to set up a wireless network and how Wi-Fi works.

A wireless network is built-in of a broadband internet connection from a cable, satellite modem or DSL. Attach this modem to the wireless router, this wireless router create a network by distributing a signal.

This is called as LAN (local area network). This LAN is set up at computer peripherals such as your laptop, printer or desktop. Each device has its own MAC (media access control) address. The router uses this address to assign each machine on your network with an IP address. The MAC and IP addresses will be useful when you look to detect whether someone is stealing your Wi-Fi.

Some of the important terms related to Wi-Fi are, a SSID (service set identifier) is the name that identifies a wireless network like Net gear or ASUS. Most commonly used standard Wi-Fi speed is 802.11n, which is capable of up to 600 megabit per second data transfers and 802.11ac is the next standard and it allows speeds over one gigabit per second. There are two different wireless frequencies 2.4GHz and 5GHz which are used in wireless routers.

Setting up a Secure Network

Is your wireless internet connection is running slowly? Do you have discontinuous losses in Internet access? There are lot of things would cause a slow connection like your Internet service overloaded with traffic or your provider may have issues, interferences to your Wi-Fi router from other electronics, or simply having trouble in your home to get a signal to your computer.

You will have only one way to prevent wireless squatters from using your internet connection i.e. a password.

The basic element of wireless security is an encryption protocol such as WPA2. Just set up WPA2 security and set a password on your wireless router. The password should be easy to remember for you and that’s not easy for others.

Most Wi-Fi routers are reachable from a connected device via the address http://192.168.1.1. Most router manufacturer’s use a simple words like “admin” and “root” to login and logging in is easy. This will take you to change all kinds of settings, including your wireless security. If routers use the same local address or same login/password, couldn’t anyone get in there with your security setting? Without a password, your wireless network is open for anyone to step on. You must change the router’s login information and it will keep almost everyone from messing with your router.

Detecting Wireless Piggybacking

With WPA2 security, anyone is not likely to piggyback on your network. There is a way to spot squatters. Every device connected to your network, has a unique IP address and MAC address. You can easily see a list of connected devices on the settings pages for your wireless router. You will also count the number of devices connected whether it doesn’t show a name in the router’s client list.

The router can hide its SSID that means it will not show up for anyone and you will also set up a wireless MAC filter to “whitelist” devices. This makes a bit harder for guests to get online at your house. There is an easy way to stop serious hackers by using a better password. Your network will be safe, if the password must be longer and harder to guess. You must not have to worry about keeping tabs on who connects to your network with a strong password.
