Q:Are there any differences between the WiFi receiver, routing, signal amplifier, repeater and signal intensifier?
Differ.The WiFi receiver is the wireless network card.Routing is the use of a IP address by multiple users.
Q:What is the difference between a router, a hub, a switch, and a repeater?
Hubs:HUB is a basic device in the data communication system. It is the same as the transmission medium such as twisted pair. It is a hardware device without any software support or very little management software. It is widely used in various occasions. The hub works in a local area network (LAN) environment, like a network card, applied to the first layer of the OSI reference model, and hence is referred to as the physical layer device. The hub is internally interconnected with electrical appliances. When the LAN environment is maintained as a logical bus or a ring structure, a physical, star, or tree network structure can be built entirely on the hub. In this respect, hubs play the role of multi port repeaters. In fact, the hub is actually a repeater, the only difference is that the hub can provide more port services, so called multi port repeater hub.
Q:Should the two wireless routing be chosen as a relay mode or a bridging mode?
For home or small network users who use wireless routers, relay and bridge access is a concept.
Q:What brand of repeaters is good for you?
The repeater is mostly stable, and then the effect of signal enhancement.
Q:How is the Tengda 11n wireless router set up as a repeater?
1, if the Tengda route is more than 300M, it is recommended to set up wireless WAN;Setting steps: (1) set A routing, normal Internet access, wireless settings - basic settings - modify SSID, channel 6, security mode WPA-psk, encryption rule AES, set wireless password - determine;(2) enter the B wireless routing interface settings - basic settings - channel 6; senior set the -WAN media type - select "wireless WAN" -- open the scanning -- the choice of the first SSID (MAC) added, channel, encryption, password set will automatically restart after restart; modify the LAN port address for IP determination.(reference link:, if Tengda routing is ordinary 150M routing, if the main route is not the same manufacturer, setting up wireless WDS may not be successful;Setting steps: (1) set the main route A, normal Internet access, wireless settings - basic settings - modify SSID, channel 6, security mode WPA-psk, encryption rule AES, set wireless password - determine;(2) enter the B routing interface, wireless channel, SSID, security, encryption and password rules must be consistent with the main routing; wireless settings - Open WDS- to scan the main routing - add MAC address; modify the LAN port IP: the main route of the same segment of different IP (if A routing, B routing; the DHCP server - off - OK - restart routing.(3) re entering the main routing settings interface - select WDS-, open scan - add secondary routing, MAC address - save.
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: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:Ask the difference between the base station and the repeater
Repeater is a repeater, it is responsible for linear amplification of the base station signal, usually in room division, cell signal coverage, for some of the base station signal coverage of blind spots, weak areas used
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?
The channel does not mean the signal strength, but the current operating frequency of the wireless device.
Q:Is intelligent access control available offline?
No more goalkeeper machine for personnel management within a specific area of import. Can be used in public doors, offices, hotels, clubs and other places of entry and exit. This machine adopts the advanced contactless IC card technology, and uses the contactless IC card instead of the "key" or "pass" for daily use, which is convenient and fast to use, and safer than the two. At the same time, equipment and software corresponding with the machine, can be used for online patrol, attendance (network status), access control, capture the fire linkage linkage system, BA.
