Q:Which layer does the repeater run on the OSI model?
Applicable to the same two types of network interconnection, the main function is to transmit or forward data signals to expand the distance of network transmission.
Q:What's the function of a repeater? Where does the repeater work?
There are many kinds of repeaters, radio relay and wireless network relay. The common one is wireless network. In order to make the signal transmit farther, wireless relay is used.
Q:Repeater with output network socket
If it is a repeater, generally have WAN / LAN adaptive reaction, also can output the network, but the premise is the output of the network relay success, otherwise can not be used.
Q:Routers, repeaters, two computers are connected, and how to form a LAN
Routers do not have special settings (but to open the DHCP service), and the repeater uses the AP mode (to turn off the DHCP service and modify the repeater LAN address with the same network segment of the router, but not IP).If wireless, it's simplerRouters do not have special settings (but to open the DHCP service), and the repeater relays the signal to the main router via the wireless signal in the relay mode, and forwards the signal.
Q:Request WiFi repeater settings, I do not know the other router's model and password, but I know the WiFi password!
Close your router DHCP service and note that the two routers cannot be the same gateway. Commercial router settings method: your router MAC address, such as the other router, and then the other router MAC address, such as your router. Close dhcp. Gateways can not be the same. Restart your router after you have finished setting up
Q:Do you need the same brand as the WiFi router using the WiFi repeater?
If you buy a new router, it is strongly recommended to buy the same brand.
Q:What's the difference between a wireless AP and a relay router?
Wireless AP is the use of wireless devices (mobile phones and other mobile devices) users access to the wired network access point, turn the wired broadband into wireless WiFi, this WiFi is AP.
Q:What's the difference between AP and relay?
In wireless communication, the function is to allow a large number of users to share a relatively small number of channels within a cell, that is, allocating channels to each user on demand channels from the available channel library.
Q:Why can't the phone be found in the WiFi network that is set up by the computer? Network attributes can be seen, how should we correct?
When setting up the relay AP, you need to check that the name is the same, so it's better to have a different name! There is the relay when the channel is consistent, inconsistent, you can not successfully relay, and there is too far away from the route is too far away, and still can not receive
Q:What is a relay power supply?
Half duplex, that is, Half, duplex, Communication, means that at any time during the communication process, information can be transmitted from A to B, and from B to A, but only in one direction. When half duplex mode is adopted, the transmitter and receiver of each end of the communication system are switched to the communication line through the receive / output switch, so as to make the direction switching, therefore, the time delay can be generated. The receive / output switch is actually an electronic switch controlled by software.
