The WiFi amplifier does have some effect. Four or five years ago, I was connected to ChinaNet in the school dormitory facing the opposite building. I could still access the Internet even if the Internet was disconnected at night. I have been using it for a year or two and it has worked repeatedly.
There are two types of WiFi signal amplifiers
One is a wireless repeater, which works by forwarding or extending WiFi signals. .
When the distance between you and the WiFi router is not far, but the signal is very weak, you can use the repeater directly, provided that there is power supply for the repeater. Work. After installing the repeater, connect to the repeater through your mobile phone or computer to set it up. Connect the WiFi signal for Internet access, and you can directly amplify the WiFi signal.
The other is a high-power WiFi receiver, which is the kind I used in school before. It can receive long-distance signals and can search for them about 100 meters away.
This kind of device is usually connected directly to the computer through a USB data cable and is powered by USB, so it can be fixed outdoors facing the direction of the WiFi signal. After the computer installs the driver, it can be directly connected to the computer. Search WiFi to surf the Internet.
However, using the Internet is not a long-term solution. It is okay if you can use it for emergencies for a while. In the long term, it is recommended to choose a stable and effective network.
In fact, it is much more advanced than it was a few years ago. Mobile cellular data is now very cheap and the speed is much faster. You can use mobile phone hotspots to access the Internet. This may More convenient.
Useful, WiFi signal amplifier is designed to solve the problem of incomplete signal coverage. The principle is the same as using wireless bridging between two routers, except that the WiFi signal amplifier will The function is made into the product and the setting process is simplified, making it more convenient for users to operate and use. In this case, using it is the most cost-effective method.
WiFi signal amplifier is also called a wireless repeater. When it receives the original WIFI signal, it is amplified internally and then emitted to expand the signal coverage. General setting steps As follows:
1. Place the amplifier in a suitable location. If it is too far away, the effect will be poor, and if it is too close, it will not be able to expand the signal, so it is best to install it at the edge of the original signal.
2. There will be a certain network delay when the amplifier forwards the WiFi signal, which is unavoidable. The most stable method is to use a wired connection to the secondary router, but it depends on your relationship with your neighbors. .
If there is wifi nearby and you know the wifi password, then you can buy a wireless router, preferably TP-LINK, which can receive The other party's WiFi signal and the amplification of the other party's signal are usually called wireless bridging.
Specific operation methods:
1. Go to a computer store to buy a TP wireless router. If you don’t want to set it up, you can Just ask a computer technician to come to your door to install and debug it, which saves time, effort, convenience and speed!
2. Set up by yourself:
1. First, after the router is powered on, use your mobile phone or computer to find your new router. The router's wifi is connected well, but the new router cannot be connected without a password.
2. Open the web browser on your computer or mobile phone and enter 192.168.1.1 to log in to the router settings. You will generally be reminded to set the router’s login password and wifi password. You can set Then log in to the router again and enter the router settings as well.
3. Enter routing settings--Internet settings--WAN port connection type--select to obtain an IP address automatically.
4. Find the application management--wireless bridging--start settings--it will search for nearby wireless signals---find the circle in front of the name of the wireless WIFI you know. Click Select - You are asked to enter the password of this wireless wifi - after the password is correct, it will display that the wireless bridge is successful.
At the same time, you will be asked whether you want to change your own router password to be the same as the other party's router name and password? You can keep the same or change it to your own name and password.
5. Some routers need to turn off their own router’s DHCP server. Generally don't worry about him.
6. After completing the above operations, the signal is as full as your own broadband, and the network speed is also very fast. Congratulations, you can now surf the Internet safely and quickly.
I have done this before. I used the master key to crack the wifi password upstairs, then entered the router management through 192.168.0.1, and guessed the router's management password. Then I went in, obtained a broadband account, and guessed the broadband password.
Of course the useful thing is that all you need is the wifi password. Buy a router yourself and place it on the TV cabinet by the window. It can receive the wifi signal upstairs very well. Then use bridging to expand the signal for your own home use. This way you will be able to use the network well.
However, in order to be able to use the network for a long time, it is best to set the device speed limit in the router. Don't occupy too much bandwidth, so as not to slow down everyone's network speed. Daily use will not have an impact.
Please adopt if you are satisfied. However, now China Mobile provides free broadband. If you don’t have a mobile number, you can borrow a friend’s number to register and you can use broadband for free.
Responsibly speaking, if you use the neighbor's Wifi and buy a Wifi signal amplifier, the effect is the same as directly connecting to the neighbor's router.
First let’s understand the working principle of Wifi signal amplifier, and it will not be difficult to find the answer. The so-called Wifi signal amplifier is actually a mini wireless router that works in bridge mode. The specific working mode is to use the Wifi signal that can access the Internet as the network access source, and then the Wifi signal amplifier transmits it through its own Wifi signal to achieve the effect of signal amplification.
Generally, the Wifi signal amplifier will generate a brand new SSID number. Of course, there are also some models of Wifi signal amplifiers that will generate an SSID that is the same as the Wifi signal source. From a working principle point of view, if the Wifi signal source itself is very weak, it is useless to install a Wifi signal amplifier, after all, the signal source is too weak.
One thing that needs to be explained is that after installing the Wifi signal amplifier, the Wifi signal is indeed stronger, but the Internet speed will not change in any way because the network speed of the signal source itself is slow. Sometimes, there will be situations where the Wifi signal is very strong, but the Internet cannot be accessed.
So, the questioner uses the neighbor’s Wifi, so buying a Wifi signal amplifier is of little use. It is better to discuss with your neighbors, pull a network cable, and buy a wireless router to use it.
If there are no points:
1. Lingju sets your router’s MAC address as a blacklist. You It will never be useful;
2 Lingju named the router’s wifi in Chinese, but some devices (signal amplifiers) cannot receive it;
< /p>
3 Lingju hides your wifi username. If you don’t know it, you can’t use it;
4 Lingju limits your device IP Flow, you are also depressed;
5 If good neighbors in China take the initiative to share, you can buy equipment and use it.
Assume that you use your neighbor’s WIFI with your neighbor’s permission
If you want to improve the quality of your network WIFI, buy a signal amplifier. Or relays are useful, but I personally feel that compared to second-hand or brand-new tplink wireless routers priced at sixty or seventy yuan, the latter's network quality and network coverage are more stable
< /p>
After you purchase the wireless router, connect the wireless router to the power supply. You only need to search for the WIFI signal of the wireless router you installed on your mobile phone. The WIFI signal at this time does not require a password. According to the label on the back of the wireless router Log in to the wireless router with IP address or network address
After logging in, you can search for the neighbor’s WIFI signal by turning on the wireless router relay function or bridging function, and use the WIFI password , the bridge can connect to the Linjia wireless router WIFI normally
However, it is best to modify the default IP address of the purchased wireless router to prevent IP address conflicts of the wireless router
< p>If you buy a WIFI signal amplifier, you can of course use the neighbor's network, but the effect is not very ideal. It is recommended to install the cheapest broadband directly.
Wireless amplifier is a good solution when there is no reserved network cable or the network signal is poor. The questioner wants to use a wireless amplifier to interfere with the neighbor's network. It is also a very simple way. Wireless amplifiers can expand the wireless signal strength of your neighbors' homes, allowing your own home to have relatively strong wireless signal coverage, but the gain of wireless amplifiers on network speed is almost zero. In actual use, we will find that the wireless signal coverage has been greatly enhanced, but the network speed has not been significantly improved.
Therefore, the solution of using wireless amplifiers to block the network is not particularly good, because it will not reach our ideal network speed, but will bring us more troubles. Furthermore, your neighbor probably won't let you use the extender without restrictions to use their home network. Even if he agrees, he will probably use other means to limit your speed, which is not good.
It is strongly recommended that the subject install a broadband by himself. Broadband is very cheap now. For example, where the author is located, 40 yuan can get 30Mbps network bandwidth a month, and 59 yuan can get 100Mbps network bandwidth a month and comes with a free mobile phone card.
Generally speaking, it is not recommended to use extenders and other methods to expand wireless networks. In the current environment, the cost of installing an independent broadband is not high. The usage effect is second to the wireless extended network, which is N levels better.
The signal will be enhanced. The signal here is the wireless signal of your mobile phone, but the network speed will not change. Even if there is an improvement, it can be said to be a negligible effect. The effect is to make it possible to receive signals from places where you could not receive signals before.
You can use it! ! However, it is still recommended that you negotiate with your neighbors to pull down the network cable! It will be much more stable and the speed will be improved accordingly!
There used to be a wireless amplifier that looked like a small dish! You need to use the USB that comes with it to plug it into your computer. It is actually a wireless network card that is used to receive wireless signals, but the wireless signal will be enhanced! However, it can only be accessed by computers and cannot be accessed by mobile phones! And it is old and will not support the latest protocol, so the speed will not be very fast! Not recommended to buy
In recent years, I have been thinking about a small one with two antennas, called a wireless extender! It comes with a plug that can be plugged into a socket at home to wirelessly bridge other people's wireless signals. Of course, you need to set it up according to the instructions. It is relatively simple to set up! You’ll know it at a glance! Completely Chinese! It can be flexibly plugged into any socket in the home and can be used for mobile phones to access the Internet. If the desktop computer also needs to be connected to the Internet, then the desktop computer will need a wireless network card to receive wireless signals!
