What does WiFi mean with WiFi Internet settings

What is WiFi

Wi-Fi is a technology that allows PCs, handheld devices such as PDAs, mobile phones, and other terminals to be connected wirelessly. Wi-Fi is a brand of wireless internet communications technology, held by Wi-Fi Alliance. The goal is to improve interoperability between wireless network products based on IEEE 802.11 standards. At present, the average person will confuse Wi-Fi and IEEE 802.11. Even the Wi-Fi equivalent to the wireless internet.

Core interpretation

WiFi refers to wireless internet access, as long as there is a wireless router, you can use WiFi, WiFi internet access, fast, and do not charge GPRS traffic fee

WiFi Advantage:

First, radio waves cover a wide range of Bluetooth technology based radio coverage is very small, the radius is only about 50 feet, about 15 meters, and Wi-Fi radius of up to 300 feet, about 100 meters, the office from needless to say, is in the whole building can also be used.

Second, although the quality of wireless communication by WiFi technology is not very good, data security performance than Bluetooth, transmission quality is still to be improved, but the transmission speed is very fast, can reach 54mbps, in line with the needs of personal and social information.

Third, the manufacturers enter the field of the threshold is relatively low. Manufacturers as long as the airport, stations, cafes, libraries, such as more densely populated places "hot spots", and through high-speed lines to the Internet access to the above places. In this way, because the "hot spot" emitted by the radio wave can reach the radius of dozens of meters to 100 meters away from the access point, users will support wireless LAN laptop or PDA to the region, you can access the Internet high-speed.

Its four, no wiring. WiFi's main advantage is that there is no wiring, can not be limited by the wiring conditions, so very suitable for the needs of mobile office users, with broad market prospects. It has been expanding to more industries from the traditional health care, inventory control and management services, and has even begun to enter the family and educational institutions.

WiFi Internet Settings

Wireless Router Wireless internet setting

Wireless network settings are mainly to protect our wireless network resources are not being acquired, so we need to set password verification login to ensure security. Now let's look at the wireless router wireless settings.

① first in the wireless router Setup interface to find "Wireless settings"-"Basic settings", in the "SSID" to fill in the name of your router, you can easily fill out the main to identify their own network,

The SID name is a network-aware name, which is the name that our laptop or tablet search wireless network sees, and can be written according to your hobby.

② Click "Security Settings" to enter the Security Settings Wizard and fill out the following figure:

First select "Security Settings Options" to "WPA2", and then enter the password for the wireless Internet access network password, the password must be remembered, because laptops or tablets need wireless password to log in and use.

about why the "Security settings Options" are selected as "WPA2" here? Mainly for security reasons, the current WPA2 wireless network encryption is the most difficult to crack, some other password types are relatively easy to be used to rub the network card for brute force.

③ set the above steps, remember to click the settings interface at the bottom of the "Save" button to complete the operation.

What if you can't get on the net?

Open the browser of the computer that is connected to the current wireless router, enter 192.168.1.1 in the Address bar (part of the router is 192.168.0.1, view the router's bottom tag to be informed), log in to the current router's Web configuration interface, username and password by default are admin

At the router's network settings, first locate the router's WAN port setup options. Setting the "type" right here is the key to the problem. Commonly used types are two: PPPoE and DHCP. This choice is based on your own situation. If it is a home ADSL dial-up Internet, choose PPPoE; if it is a community broadband or hotel and other direct network interface available, you choose DHCP

If you are DHCP, you do not have to do other settings, the router will automatically get the appropriate network settings. Choose PPPoE, you need to fill in the correct username and password, this is provided by the network service providers, such as China Telecom, forget the password can play 10000 turn artificial consultation

Next, check the LAN port settings for the router. Different brand settings are similar, the most important thing is to turn on the DHCP function, so as to ensure that the device access to the LAN port or connect Wi-Fi when the router can assign IP address, DHCP delimit the IP address range to be assigned and the router's IP address in the same network segment, Like 192.168.1.X.

Finally, check the router's security settings. Check to see if there are any security policies that restrict the Mac or IP address connection, or the appropriate speed limit policy, and then shut down if the device is only specific to the Mac or IP address.

prevent rubbing net method

Login to the wireless router's settings interface, click on the Left Function list items in the "Wireless parameters"-"MAC address filter" in the right "filter rules" select "Prohibit the rule in the list of the MAC address access to this wireless network."

Then click on the "Add New Entry" button, in the new window in the "MAC address" content bar in the "type" of your M8 MAC address "" Types of Drop-down menu select "Allow", just this MAC address allows the use of no line.

The MAC address of the M8 can be obtained from the "DHCP server"-"client list" of the Setup interface without lines.

See, the Yellow line is. Copy it and then paste it into the MAC address bar in Add new entry.

Save, and restart the route for the settings to take effect.
