1. Article 2 is not true. Want to connect to the wireless network, but also want to become a wireless hotspot through the phone. A built-in wireless module can't do it. You can try, connect to a mobile or something wireless connection, you then turn on the phone's wireless hotspot function. The system will prompt you to disconnect the current connection. One is right. As for 3, you need to ask your carrier.
2, check the environmental reasons WiFi signal strength and use of the environment (such as walls, distance is too far, etc.), if the signal is weak/onThe network is slow, it is recommended to adjust the distance between the phone and the WiFi router before trying.
3, check the environmental causes of WiFi signal strength and use of the environment (such as walls, distance is too far, etc.), if the signal is weak/slow Internet access, it is recommended to adjust the distance between the device and the WiFi router before trying. Both WiFi and Bluetooth use 4G bands. If the device uses Bluetooth, it is recommended to turn off Bluetooth before testing.
4, check whether the WiFi network is normal, please compare the connection of other mobile phones to the same WiFi is normal, confirm the WiFi or mobile phoneThe reason why. If the cause is WiFi, restart the wireless router to check. At the same time, you can enter the router management page to check whether special functions are set, such as connection limit, MAC binding, and online time management.
5, solve the problem that the mobile phone can not connect to WIFI. Turn off and restart WIFI When we use a smart phone to surf the Internet, the phone will retain a network IP address assigned by the WiFi connection, it will be applied to the current Wi-Fi, if there is no address conflict, do not worry, if there is a conflict you have to turn off and restart the Wi-Fi connection.
6, Check the WiFi, please compare the connection of other mobile phones to the same WiFi is normal, to confirm the WiFi or mobile phone reason. If the cause is WiFi, restart the wireless router to check. Some public WiFi needs to be authenticated by the browser before it can be connected. To view networking rights, please go to i Manager -- Traffic management/Traffic monitoring -- Networking management --WLAN-- Enable software networking rights.
It costs nothingYou can rub the network, but at least you also have to relay the WIFI that is routed by others to have a network.
If a wireless router needs to be connected to a network cable, connect the wireless router to a cat or network cable. [Home network environment wiring] : There is cat (modem) : cat (modem) -- router wan port; Router lan port -- Computer. No modem: Network cable -- router wan port; Router lan port -- Computer.
Method 1: Replace the network cable You are advised to replace the network cable first. In addition, you can know whether the connection between the optical cat and the router is buried in the wallYou are advised to connect the optical cat to the router using one network cable. (Reason: If it passes through the wall line, the network cable buried in the wall may fail or the jack inserted in the wall may fail).
The question is a little vague, and it probably means that you want to restrict others from accessing the Internet? The router has a function called MAC address filtering, you can bind your computer MAC address and mobile phone MAC address in the router. So as long as the router is not tied to the computer or mobile phone can not access the Internet.
What is the router called that can access the Internet without connecting the network cable? callA wireless router.
1, disconnect the router from the telecom cat first.2. Pull out the end of the computer that was connected to the cat and plug it into the lan port of the router (the light with the number will light up).3. The wireless router ensures that the factory Settings are protected from previous Settings. Login router, 19216811 or 19216801, according to the instructions, please enter correctly in IE and log in router.4.
2, Hello: The router is not set: Open a Web browser, type http://19160.1 in the address bar, and press Enter. In the login window that opens, enter the user name "admin"; The password is also "admin"; Then click OK. After entering the router Settings screen, select "Setup Wizard" on the left and click "Next".
3. Ensure that the network cable is correctly connected. That is, the network cable coming from the external network is connected to the WAN port of the router or the cat, and the network cable of the computer is connected to the LAN port. After the network cable is connected correctly, be sure to set the correct Internet access account and password in the router WAN Settings. You can view the running status of the WAN interface in Running Status. If the DNS server is obtained, there is no problem, otherwise there is a problem.
4, see if your cat is connected to the network cable is connected to the WAN port of the wireless router, if connected to the LAN port of the wireless router, you can only dial up the Internet through the computer. If the connection is correct, dial on the router to see if it can be dialed through.
5, broadband network cable router can not access the Internet, thenThere are only two reasons: the router Internet setting problem the operator restricts the router Internet setting problem The network cable inserted into the computer can access the Internet inserted into the router can not access the Internet, this problem in most cases, because the user in the setting of the router, there are some problems, resulting in the router Internet setting is not successful, so the router can not access the Internet.

6. Recommended reasons for as800 bone conduction earphone: The body of As800 bone conduction earphone is an ear-hanging structure worn by both ears, but thanks to the lightweight materials such as titanium alloy used in the basic frame of this earphone, earphoneElectrical energy can be transmitted by wire. The technology is based on the principle of electromagnetic induction, similar to the working mechanism of transformers. The coils at the transmitting and receiving ends interact with each other through electromagnetic signals, converting energy into an electric current. Wireless charging technology uses electromagnetic wave propagation to convert electromagnetic energy into electric energy and realize remote charging. Electric toothbrushes were the first products to apply wireless charging technology, appearing in the 1990s. The
principle places two coils in close proximity, and when the current flows in one coil, the magnetic flux generated becomes the medium, causing the electromotive force to be generated in the other coil. Both theory and experience show that:When the current frequency and amplitude of the primary side are higher, the distance between the primary and secondary sides is smaller, and the relative permeability of the medium around the magnetic core is larger than that of the air, the transmission efficiency of the separable transformer is higher.
Electricity can also be transmitted wirelessly. Wireless transmission of data is also a kind of electrical transmission to some extent, but the power of the "electricity" transmitted is not large. Usually, the receiving end of wireless data transmission needs power to amplify the received information, so the energy required for data transmission does not need to be large. The difficulty of radio transmission is not the protocol, but the large-capacity radio transmission.
Answer 1: Electricity can be transmitted wirelesslyHowever, wireless transmission itself is not called transmission and induction. Answer 2: The phenomenon of lightning striking the ground cannot be counted as transmission, which is breakdown. Answer three: The air is not conductive is the same as people say that the cold does not kill people.
Third, the 2-meter beacon is used in the same house using a charging device can provide electricity for multiple portable appliances. The researchers also say the coupling method is harmless to both humans and animals. Wireless power transmission technology is going well: Lighting a 60-watt light bulb at 2 meters, Massachusetts Institute of Technology researchers have announced a way to power a 60-watt light at a distance of 2 metersThe light bulb. Scientists believe that the technology is expected to be able to charge the device without the need to connect the power cord.
