First of all, you need to know which wireless signal needs to be expanded with Tengda A 12 wireless extender? And the password of this wireless signal. This problem needs to be solved by everyone themselves.
For example, in this demonstration, I will use Tengda A 12 to expand this wireless signal. Its wireless name is www. 192ly.com, and its wireless password is 192ly.com.
If you are not sure, you can log on to the settings page of the main router, find and open it? Wireless settings? Or? Wi-Fi settings? Check the wireless name and password of the main router, as shown in the figure below.
Check the wireless name and password of the main router.
Step 2: Connect the wireless signal of Tengda A 12.
When your Tengda A 12 extender is connected to the power supply, it will send out the default wireless signal; The sticker on Tengda A 12 fuselage can see the name of the default wireless signal, which has no password.
When setting up Tengda A 12 extender with laptop, you need to connect the laptop to this default wireless signal first. Settings can only be made after connection.
Connect the laptop to the default wireless signal of Tengda A 12.
Important note:
Please don't worry, when your laptop is connected to the default signal of Tengda A 12, it is normal.
Although the laptop can't access the Internet at this time, you can still set up an extender. What does this question involve? Wireless LAN? Communication technology, interested users, please search for information on your own Baidu wireless LAN.
Step 3: Set Tengda A 12 expansion signal.
1. Open a browser on your laptop and type: re.tenda.cn? Or? 192. 168.0.254? , you can set the interface of Tengda A 12 extender.
Enter: re.tenda.cn or 192 438+068.0.254 in the browser.
Possible problems:
After entering re.tenda.cn or 192. 168.0.254 in the laptop browser, the setting interface of Tengda A 12 extender cannot be opened. For the solution to this problem, please read the following tutorial:
What should I do if the setting interface of Tengda A 12 cannot be opened?
2. At this time, Tengda A 12 expander will automatically scan the nearby wireless signals; In the scanning result, select the wireless name of the main router->; Then click Next, as shown in the figure below.
Select the wireless name of the primary router.
3. Enter the wireless password of the main router and click Finish, as shown in the figure below.
Fill in the wireless password of the main router.
Important note:
In this interface, the option "The wireless name and password of the extender are consistent with the superior wireless signal" is selected by default, that is, the wireless name and password of Tengda A 12 extender are exactly the same as the superior wireless signal.
But in this place, you can also turn off this option, and then manually set the wireless name and wireless password of Tengda A 12 extender, which may be inconsistent with the parameters of the superior wireless signal, as shown in the figure below.
In addition, set Tengda A 12' s own wireless name and wireless password.
4. At this point, the system will automatically expand the wireless signal of the main router, as shown in the figure below.
Automatically expand the wireless signal of the main router
Wait a few seconds, and the prompt of successful expansion will be displayed, as shown in the figure below.
Tips:
(1). If the option "The wireless name and password of the extender are consistent with the wireless signal of the superior" is selected in the setting of step 3.3, the laptop can be directly connected to the wireless signal of the original main router.
(2) If it is set in step 3.3. The option "The wireless name and password of the expander are consistent with the superior wireless signal" is not selected;
The wireless name and password of Tengda A 12 extender are set separately; At this point, you need to connect your laptop to this wireless signal set separately.
A router is a device that connects a local area network and a wide area network in the Internet. It will automatically select and set the route according to the channel conditions, and send signals in turn by the best path. Routers are the hub of the Internet and the "traffic police". At present, routers have been widely used in all walks of life, and products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The main difference between routing and switch is that switching takes place at the second layer (data link layer) of OSI reference model, while routing takes place at the third layer, namely network layer. This difference determines that routers and switches need to use different control information when moving information, so they realize their respective functions in different ways.
Routers, also known as gateway devices, are used to connect multiple logically separated networks. The so-called logical network represents a single network or subnet. When data is transmitted from one subnet to another, it can be done through the routing function of the router. Therefore, the router has the function of judging the network address and selecting the IP path. It can establish flexible connection in multi-network interconnection environment, and can connect all kinds of subnets with completely different data grouping and media access methods. The router only accepts information from the source station or other routers, and belongs to an interconnected device in the network layer.
Router is the main node equipment of Internet. Routers decide the forwarding of data through routing. The forwarding policy is called routing, which is also the origin of the router name. As the interconnection hub between different networks, the router system constitutes the main thread of the Internet based on TCP/IP, which can also be said that the router constitutes the backbone of the Internet. Its processing speed is one of the main bottlenecks of network communication, and its reliability directly affects the quality of network interconnection. Therefore, router technology has always been in the core position in campus network, regional network and even the whole Internet research field, and its development course and direction have become a microcosm of the whole Internet research. At the moment when China's network infrastructure and information construction are in the ascendant, it is of great significance to discuss the role, position and development direction of routers in the internet for domestic network technology research, network construction and clarification of various specious concepts about routers and network interconnection in the network market.
