Q: Why is home installed wireless network repeater, can not get on the network?: Summary: in accordance with the instructions set the router router login to the routing management interface (that lost attempts to enter 192.168.1.1 or 192.168.0.1 in the browser address bar enter the default account password is admin), use the setup wizard, broadband connection type PPPoE, and then enter your internet account and password below, then select the automatic connection or on-demand connection, and then save. Then check to see if the DHCP service has started and that it is in the startup (open) state. Because you need to use wireless, you also need to open the wireless function (usually on a related page) when you need to go to the wireless settings page of the wireless routing at the same time. Save and then quit. Finally, go into the system tool and restart the router (simply unplug the power line and wait a minute to plug it in). Other advanced settings on the router are not busy at the moment, and you can configure it when you are familiar with the routing settings.

Q: What are the functions of repeaters and what are their characteristics and disadvantages?: Intermediate relay relay electrical signal, usually have normally closed, normally open each four pairs of contacts, the coil was attracted by electricity, often open on the closed, often closed off! Features are flexible, easy handling, reducing a lot of switches, lack of wiring trouble,

Q: What's the difference between unlimited wireless trunking and wireless bridging?: Wireless relay and wireless bridging differ mainly in the device operating mode. White spots are the applications. A radio relay can be understood as a device that receives signals from other devices. Re launch with one's own center.

Q: What is the function of the network relay device?: Each segment can use different communication rates.(5) reliability is improved. When a network fails, it usually affects individual segments only.(6) performance is improved.

Q: Repeaters, hubs, two - layer switches, three - layer switches and routers work on the OSI reference model layer: The repeater works on the physical layerThe hub works on the physical layerThe two layer switch works at the data link layerThe three layer switch works at the data link layer and the network layerRouters work at the network layer

Q: What is the difference between repeaters and hubs?: 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: How to connect the router Tuoshi wireless bridge repeater: 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.

Q: What is the principle of fiber repeaters?: A light emitting diode or an injection laser is used to generate an optical pulse, and a lens is used to focus the light pulses into the optical fiber medium so that the light pulses are transmitted along the line in the optical fiber medium. From the principle of internal total reflection, light pulses are easy to move through optical fiber lines. The principle of internal reflection in fiber shows that light can not flow out of glass when the incident angle exceeds the critical value;

Q: WIFI signal, power cat or repeater?: Power cat data transmission speed and stability can not meet the requirements of audio data, so it is not recommended to use the power cat

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.
