With the popularity of smart devices, I believe everyone in the Internet is using WIFI at home this time, and some people have a wireless router installed at home, but installed in the living room, the room may not receive WIFI, installed in the room In the living room, I received no WIFI. I installed it on the second floor. On the third floor, I received no WIFI. Especially for those big families, there are several layers of several hundred square feet, the signal is really weak to be crazy, people feel it may even be fake WIFI.
As shown in the figure, if Router A covers a red area, those areas that are not covered will be weak or no signal.
At this time, idle homes or old routers can be in full bloom in the second spring, with idle or old routers to expand the wireless network and expand coverage.
两个 I am using two routers
Principle: Use the wireless router's wireless relay mode for network expansion.
Assume that an external network interface such as a broadband connection is an A router. A router sends a WIFI signal, and B router receives the WIFI signal of the A router and then sends its WIFI signal to the surroundings.
Specific implementation of operations:
进入 Enter the WIFI network sent from the A router and enter the gateway address of the network where the router is located to control the A router. You can first check your IP address (point icon in the lower right corner of the status bar network icon> click WIFI name> properties).
In general, if the IP address is 192.168.1.XXX, the gateway address is 192.168.1.1.
If the IP address is 192.168.2.XXX, the gateway address is 192.168.2.1, and so on.
↑ Select PPPoE dial-up Internet
↑ Turn on the encryption function, choose the encryption mode as WPA2-PSK, the encryption algorithm as AES, and the PSK password (WIFI password)
↑ Then enter the WIFI network sent from the B router, enter the gateway address of the B router, and control the B router.
↑ Search for the WIFI signal sent from the A router, enter the WIFI name of the A router, select the encryption mode as WPA2-PSK, the encryption algorithm as AES, and enter the WIFI password of the A router. In this way, the relay mode of the B router is successfully opened, and the WIFI signal of the B router is sent out.
Note: The operating system of each brand of router is different, the interface may be slightly different, but the principle is the same.
Whenever you go to the mall to search for WIFI, you will find several WIFI networks, allowing you to choose the WIFI with the strongest signal. So big shopping malls, but also use the relay mode of the router to cover the WIFI network, but the bandwidth to connect to the external network with optical fiber is much larger than the home.
Hybrid inverters charge the batteries using solar power during daylight. If the battery goes low, or during insufficient lighting, they charge the batteries from the Grid. These systems automatically switch between the solar power and the Grid.
This is great way of replacing polluting diesel generators. Your electricity bill will be reduced and your diesel bill will be eliminated.
