Q:A cable line can use two wireless repeaters simultaneously
A's LAN port comes up to B's LAN port, then closes B's DHCP service, and then the computer can connect to B, the same effect as A.
Q:How does ZigBee implement the routing relay function?
If you need to know is with their development, the need to be familiar with ZigBee protocol stack, this time, now a lot of ZigBee transmission module with the route relay function, for example of this kind of ZM5168 module, routing functions are very easy to use.
Q:Repeaters can amplify several WiFi signals, such as three WiFi in my house, and whether the three signals will be very good!
No, the repeater can only amplify one route WiFi at the same time
Q:How to set up slow relay network?
Method 1: connect the repeater to your computer with a network cable, not WIFI. (this method is the simplest, but it's very messy and many computers are sharing more chaos)Method two: buy a wireless router, wireless router and repeater cable connections, and then the signal WIFI through the sharing of the wireless router, the reason is very simple, only the wireless repeater, without wireless forwarding, so the bandwidth of all for receiving and forwarding by cable to the router to complete. (this method is practical and suitable for wireless sharing, but the device cost is high)
Q:Are signal amplifiers or repeaters powered?
Add switches and something like that in 100MA repeater is a device for amplifying signalsBut now that HUB has been replaced by switches, the white spot is that HUB is out of date
Q:What's the principle of fiber repeaters?
There are more erbium laser repeater is adding rare metal in a fiber, the nearby photon in a state of activation, there is a small amount of light once into the fiber segments, can impact these active light source, the optical signal instantly increased several times, thus the optical signal amplification.
Q:Is it possible to relay a repeater after a wireless router?
And you can extend the coverage of the WiFi signal more, but the repeater can be no longer used. Its alternative is the Tencent, which is now very popular online, WiFi, when it comes to signal strength,
Q:What is the difference between repeaters and hubs?
A repeater is a network interconnection device on the physical layer that is used to regenerate signals (i.e., amplify and shape the original signal).
Q:How to make idle routers at home used as relay stations?
No wireless relay, you need to use the bridge, the steps are more complicated, direct Baidu 'wireless routing bridge', you follow the steps you can do!
Q:What's the difference between a wireless AP and a relay router?
The relay router is used to expand the coverage area of the wireless router, because of the structure of the housing, the router wireless WiFi transmission process will be the wall, furniture and other items of occlusion, WiFi wall after the signal transmission distance is reduced, weakened, or even can not receive WiFi, so use (relay router) in signal with two places receiving lattice weakened WiFi, then a WiFi, this will play a role in signal amplification, this is called relay.
