Q:How does the COMFAST wireless relay router use the relay function (model CF, wR360N)?
Confirm the wireless router relay network normal after entering the "Wireless Settings" - "basic settings", you can see the wireless router's "SSID", this is what we are going to the relay wireless network name, and then set behind the relay will be used when the note down.Also need to pay extra attention to is, by wireless signal relay cannot use "automatic" channel, some routers default will be set to auto channel, it will cause the router to restart, because different channel repeater relay failure, channel 1, 6 is 11, etc..
Q:Can wireless routers be used as repeaters?
PS: if there are a lot of WIFI around, it's better to set a good WIFI name so that you can distinguish between them.
Q:What are the differences and uses between wireless trunking and wireless bridging?
The relay mode allows multiple client link bridging mode allows only the only authentication client relay wireless bridging higher than. Wireless bridging means connecting two or more LAN or WAN wirelessly. Repeater is the extension of the length of wireless signals (not amplified signals), of course, is a wireless bridging function, but the use of different, so the relay can not replace the bridge. For example: A----B----C, a total of three sites, if A and B can be wireless bridging, B and C can also be wireless bridging, but A and C because of distance, can not wireless bridging. If you want ABC to be wirelessly connected, what's the solution? Then we can use ABC as a relay function (which is also one of them). After A and B relay, B relays C again. You should understand it, in addition, the relay can be connected to a wireless router with no bridge, the bridge to set the binding of MAC and IP, and the relay is not, as long as the wireless router signal can absorb (of course with WEP or WPA password you need to fill in).
Q:The role of field bus PROFIBUS DP/FMS isolation repeater is also discussed
The industrial design of PROFIBUS optical fiber communication repeater and DP/FMS bus signal isolation and data communication, with the total line photoelectric isolation, signal regeneration, extend the transmission distance, increase the number of nodes and other functions.
Q:What does "universal relay" mean by a router?
Router relay is a kind of wireless relay mode of wireless router. It is the function of wireless routing in network connection, which can relay and amplify the signal, thus extending the coverage of wireless network.
Q:Who knows the principle of the repeater? My repeater is always disconnected. What's the reason?
When the working state is stopped, the temperature of the circuit device will decrease. When the temperature is lower than the value of the temperature protection, the circuit will re-enter the working state and the network will be connected again. If this problem can be verified by helping it to cool, verify, or change a repeater directly;
Q:Which of the two WiFi repeaters is good?
This is just a mini wireless router, almost all, not the actual use of the difference between 150M and 300M, connected with the mobile phone wireless devices such as wireless network card rate determined by the wireless network card is generally fast. 150M is enough. Watch your favorite style and buy it.
Q:RS485 photoelectric isolation relay
The 485 repeater provides the function of relaying and amplifying the RS-485 signal, which can extend the communication distance of the RS-485 bus and increase the load capacity of the RS-485 bus.
Q:What network problems can a repeater solve?
Repeater (Repeater) weighing and sending device is one of the most simple, but also the most widely used interconnection equipment. Repeaters are only suitable for Ethernet and can link up two or more than two Ethernet links. The repeater amplifies and amplifies the data signals transmitted over the cable, and then retransmit them to other cable sections. For protocols above the link layer, several sections of cables interconnected by repeaters are not different from a single cable (except that the interrupt itself causes a certain time delay).
Q:Who used the WiFi repeater? Is it easy to use?
In fact, if you are using a new wireless router, you can try and buy a wireless router to bridge, WiFi repeater function and it almost ah.
