Q: How to set up the tplink router's repeater?: 1, using the Tp-link router B default DHCP server is not opened in AP mode, not for the computer to automatically assign IP addresses, so also need to configure the computer wireless network connection IP address, can log into the router management interface, or the wired connection, the computer wireless network connection IP address is set to 192.168.1.X, subnet mask settings: 255.255.255.0, setup is complete, click OK to take effect.2, connect to the router in the IE browser, enter the 192.168.1.253, enter the default login account and password admin Pulian, open B router management interface.

Q: What is a relay device and a conversion device?: Due to the effect of transmission line noise, carrying digital signal or analog signal can transmit information in a limited distance, repeater function is regenerated and sending the received signal, thereby increasing the signal transmission distance. It is the simplest network interconnection device that connects two or more network segments of the same network. If the length of the cable Ethernet Repeater often use bus standard, thinnet each maximum length of 185 meters, up to 5, thus increasing the repeater, the maximum length of the cable network can be increased to 925 meters. In general, the network at both ends of the relay is a network segment rather than a subnet.

Q: What's the role of the DMX repeater?: Interface standard: compatible with EIA/TIA, RS-485, asynchronous two line, half duplex and RS422 asynchronous, four line full duplexCommunication rate: 300bps-115.2Kbps, built in Turbo Turning, automatically select baud rateEnter: two lines RS-485, (485+, 485-), four lines, TX+, TX-, RX+, RX-Output: two line RS-485 (485+, 485-), four line TX+, TX-, RX+, RX-The plug connector: type terminal (5.08mm).Isolating voltage: 3000VPort protection: built in TVS (common mode and differential mode) and self recovery fuse, power over flow and voltage protectionThe unique design enables the RS422-RS422, RS422/485, RS485-RS485 and any combination of relaysPower input: 9-30VDC; 2.2W (MAX)Operating temperature: -25 DEG C, ~75 DEG CStorage temperature: -25 DEG C, ~80 DEG C, relative humidity: 5-95%, without condensation

Q: Repeaters, hubs, two - layer switches, three - layer switches and routers work on the OSI reference model layer: Repeaters and hubs are first - tier physical layers that work as the OSI reference modelThe two layer switch operates on the second layer of the OSI reference model data link layerThree - layer switches and routers operate on the third - layer network layer of the OSI reference model

Q: What is the principle of fiber repeaters?: First, the transmission of optical signals is explained. When the transmission of the optical signal in the optical fiber with a longer distance and the signal decreased, when less than a fixed value when the optical receiver at the receiving optical signal can not correctly identify signal encoding, will lead to error, so at a certain distance from the optical fiber transmission, with a fiber optic repeater, the light amplification the signal can support long-distance transmission, similar to the gas station.

Q: Do you need the same brand as the WiFi router using the WiFi repeater?: If you already have two routers, the brand is different, you can try, so as not to waste.

Q: The repeater connects to the wireless network of the left neighbor's home, showing the wireless channel -1, and even the wireless network on the right side shows the wireless channel -6. What does that mean?: Channel is different signal frequency transmission, intelligent routers can automatically adjust, if there is no repeated frequency interference, network speed will be faster

Q: How does the COMFAST wireless relay router use the relay function (model CF, wR360N)?: To set up WiFi wireless relay, first need to ensure the wireless router relay is normal network, in order to facilitate understanding, we sometimes also known as a wireless router to the relay router or relay signal, and we want to set up a wireless relay router is called the wireless router or wireless repeater, to show the difference, don't confuse oh.The use of mobile phone or computer to be relayed to the wireless router, wireless router to the TP-LINK for example, enter the router settings page, view the running state of the router, the router has to ensure network, if the router does not relay network, the wireless Internet is not in the following.

Q: What is the difference between a repeater and an amplifier in a computer network?: The repeater signal forwarding function, the equivalent of the mouthpiece, not just for forwarding data, such as advanced relay ATM asynchronous frame relay, but also for the session and application service relay transmission; wireless network, optical network is the most used network relay, and the relay is not necessarily a transmission, can also be transfer to a plurality of base stations, such as China Mobile; relay in the process involved in supporting scheduling and scheduling algorithm, and error correction algorithm, transmission efficiency algorithm;

Q: About repeaters and common twisted pair problems: If the length of the cable Ethernet Repeater often use bus standard, thinnet each maximum length of 185 meters, up to 5, thus increasing the repeater, the maximum length of the cable network can be increased to 925 meters.
