Q: Who knows the principle of the repeater? My repeater is always disconnected. What's the reason?: Intermittent disconnection of the network, i.e., when it is still working, indicates that the configuration parameters are normal. When the WiFi repeater is in continuous working state, the protection state will stop when the working time is too long and the temperature is too high when the constitution is not very good;

Q: What is SIEMENS's bus repeater?: The 485 repeater is an optical isolated RS-485/422 data relay communication product, which can relay to extend the communication distance of the RS-485/422 bus network and enhance the RS-485/422 bus networkNumber of equipment.

Q: What is often referred to as' repeaters' in network communications?: When a network repeater is interconnected with an isomorphic network segment with the same interface and the same medium access control protocol, an instrument device is added to the network to amplify and retransmit the transmitted signal. Thus, the signal attenuation caused by the long cable line of the network segment can be avoided, and the reliability of the transmission can be effectively improved.

Q: TP routers, TP repeaters, but repeaters are always easy to drop. Why is that?: If the Internet phone or computer open Bluetooth and WiFi at the same time, WiFi will be interfered by Bluetooth, it will be very card or even unusableA plurality of wireless devices can interfere with each other if they are arranged in a space similar to a straight line

Q: Why do home networks typically use routers? Repeaters, bridges, and the like? What is the name of a direct link modem for a network?: Bridge: like a smart repeater. Repeaters receive signals from a network cable, amplify them and send them to the next cable. Bridges, by contrast, are more sensitive to the information uploaded from the checkpoint. A bridge is a technique for forwarding frames, isolating collisions according to the MAC partition block. The bridge connects multiple segments of the network at the data link layer.

Q: The role of repeaters in Ethernet?: For example, a high level may be parsed low, so it is necessary to amplify the signal before it decays so as to increase the transmission distance!In short, the main function of repeaters is to resend or forward data. Amplify the signal and increase its transmission distance.

Q: How does the relay set up the connection WiFi?: Because of the different brands, the different settings of the model will be different, sometimes very different,Take mercury mw300r for example:Remember that routers that require wireless bridging (preferably fixed channels), SSID, password types, passwords, and other data are open to their DHCPThen login to the router and change the router's LAN address to 192.168.1.2 or other addresses that are different from the main router's network segment.

Q: What are the differences between a bridge and a repeater?: A repeater is a form of bridge,1) a repeater is a device for connecting network lines, often used for two-way forwarding of physical signals between two network nodes. 2) is the most simple repeater network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.3) because of the loss, the signal power transmitted on the line will be gradually attenuated. When attenuation to a certain extent, it will cause signal distortion, which will lead to a reception error. Repeaters are designed to solve this problem.4) it completes the connection of the physical circuit and amplifies the attenuated signal to keep the same as the original data.5) in general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media.6) in theory, the use of repeaters is unlimited, and the network can therefore be indefinitely extended. In fact, this is impossible, because the network standards are specific to the delay range of the signal, the repeater can only work effectively within this set of regulations, otherwise it will cause network failure.

Q: How to make a notebook wireless relay: XP system is not available, you can use win7, 8 systems have their own trunking function. But the cell phone still doesn't work.

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.
