Q:What device is a wireless network adapter Wifi amplifier? Does it need to be charged?

A repeater is a wireless network product that implements relay and enhancement of wireless signals.

Q:What are the differences between switches and repeaters, and what are the common functions?

Repeaters are designed to solve this problem. It completes the connection of the physical circuit, amplifies the attenuated signal and remains the same as the original data. In general, both ends of the repeater are connected to the same media, but some repeaters can also do the switching of different media. 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:Why is home installed wireless network repeater, can not get on the network?

Set up the computer: set the protocol TCP/IP property. Right click on the network neighbor - Property - right click local connection - Property - Network - Protocol (TCP/IP) - properties - use the following IP addresses - all set as "automatically get the IP address" and "automatically get the DNS address" to determine. Next, open IE, tools -- options -- connect pages, click, never connect. Note that the original dial-up computer should pay attention: right click on the Internet neighbor - Property - network connection - right click on the broadband connection, cancel the default connection, right-click the local connection, and set it as the default connection. Later on the Internet, not in the computer, with that "broadband connection" or "star speed" dial, the route will help you dial directly, you turn on the computer, just go QQ, open the web page is

Q:Which of the two WiFi repeaters is good?

Repeaters are better off with routers, and the faster, of course, the better, but if the repeater is wireless, the network speed may be greatly reduced, or it may fall by half.

Q:Which layer does the repeater run on the OSI model?

The repeater (REPEATER) repeater is the connection device above the network physical layer.

Q:Can repeaters land without cables?

Yes, repeaters can log in wirelessly. The principle is that they will relay transmit a signal, when you connect (mobile phone can be connected to WiFi) after landing back switching relay mode (some repeaters used to relay more than) you can find yourself in the emission signal routing in the WiFi list, after the connection (to name) to achieve the forwarding of the original signal. In order to achieve the goal of enhancing signal propagation.

Q:What level of work does the OSI seven - layer structure work with, hubs, switches, routers?

The network segment connected by the switch still belongs to the same broadcast domain, and the broadcast packet will be transmitted on all segments connected by the switch, and in some cases will lead to communication congestion and security vulnerabilities. The network segment connected to the router is assigned to different broadcast domains, and broadcast data does not pass through the router. Although more than third layers of switches have the function of VLAN, they can also segment the broadcast domain, but there is no communication between the sub broadcast domains, and the communication between them still requires routers.

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:The greater the power, the better the ability of the WiFi repeater to receive the signal?

The sensitivity of the receiver generally has a limit, or the maximum reception sensitivity is a constant, and the reception capacity is limited by the sensitivity constant. It does not change as the power of the transmitter increases or decreases. It has nothing to do with the transmitted power. They are two different devices. It can only be said that the greater the power, the stronger the received signal.

Q:The role of repeaters?

The relay mode (1. it can enhance your home wireless router WiFi signal, such as your router placed in the library, and you often surf the Internet where is the bedroom, if you study the signal for the 5 case, the living room for the 3 grid, and 1 bedroom lattice or not, then you can put this product in the living room, simply set your bedroom to search the signal becomes a full grid! You can surf the Internet in the bedroom comfortable 2. it can extend your home wireless router WiFi transmission distance, such as your wireless router transmitted WiFi signal coverage range is 10 meters, and you need to the Internet is 20 meters, you can put this product inserted in your main routing signal area (such as 8 meters around the place) in a wireless relay, you can put your wireless router WiFi signal coverage to 20 meters Used locally.)
