As a modern citizen, it is very likely that you use Wi-fi in your daily life. Have you known the basics about wifi? We have compiled a list that can help you.
1. Wi-fi is not the Internet
Wi-Fi is a wireless method to connect one device to another in a local network, all linked together to share an Internet connection using a router.
A router is the central device of the home network. You can plug the cable in it to connect with another device that has a network port. A local network is a group of connected devices with a router. WiFi acts as the plugs to connect these devices without any cable. If the router can receive The Internet, all the connect devices would be connected to the Internet, too.
Most laptops, cell phones, and smart devices nowadays have built-in wireless transmitters . With this device, your computer would be able to discover existing networks automatically. The computer will inform you that there are networks and whether you want to connect to it.
WiFi is the abbreviation of Wireless Fidelity, which means wireless precision. In 1999, the technology was invented as a wireless equivalent of the Ethernet.
2. WiFi hotspots
A WiFi hotspot is an area with the accessible wireless network, which is often the networks in airports, coffee shops, restaurants or other public areas. You can also create your own mobile hotspot using your cell phone or any external device that can connect to a cellular network.
3. Wifi has a lot of advantages

4. Public WiFi
More and more cities are providing the people with free WiFi everywhere. Big cities are even turning old phone booths into hot spots. Connecting to the Internet, now more than ever, will be fast and free.
Unlike the isolated WiFi hot spots in restaurants or coffee shops, the government funded public wifi is faster and relatively more secure.
5. The dangers of WiFi
Using public WiFi to shop or banking can allow someone who shares the same WiFi network to access to your information, passwords, banking accounts or personal information. Unguarded, you can easily be a target for the cyber criminals.
Make sure you are safe by only entering secure sites. If the hot spot does not require WPA or WPA2 password, it can be unencrypted, insecure and vulnerable to intrusion. Also do not access sites without a “https” at the start of the address, as these sites are not encrypted. Encryption makes it hard for criminals to access without permission.
These criminals can also set up a bogus link that has the same name of an actual WiFi site to lure you into the connection. Once connected to the site, all your information will be vulnerable.
6. Make sure of your own safety
Use a virtual private network (VPN) when connecting to a public WiFi network can set up a private tunnel that will encrypt all data passed through the network.
Do not set your smart device to automatically connect to any WiFi network so that you can avoid linking to a bogus system.
Turn off WiFi when you are not using it.
In the recent years, WiFi Technology is growing rapidly and is used all over the world. It has great potential, but along with the advantages, there are many downsides.
