Q:Differences between routers and switches and repeaters: Repeater work in the first layer (physical layer), signal amplification and hub function itself in a collision domain, at one time t, only one data packet through.

Q:What's the 485 repeater for?: 485 repeater product features:In the 485 bus, if the 485 transmission line reaches a certain distance and is in a complex external environment, it is vulnerable to external interference such as electromagnetic interference in the external environment. Efficient lightning protection devices in repeaters can effectively suppress lightning (Lightning) and ESD., and provide lightning surge protection power per line of 600W. It can absorb external interference such as electromagnetic induction in external environment. Thus, the stability of the 485 bus is protected.

Q:What does wireless relay mode mean in routers?: 1 、 the wireless relay mode in routers refers to the routing function of shutting down routers, and routers act as repeaters for wireless network signals only.2, router wireless relay mode setting method is as follows,

Q:How can wireless AP (trunking) be used to connect wireless routers that shut down SSID broadcasts?: Wireless networks with SSID broadcasts have been closed, that is, wireless network names are hidden. Wireless Internet devices are unable to find the wireless network.

Q:What is the principle of fiber repeaters?: First, the transmission of optical signals is explained. When the transmission of the optical signal in the optical fiber with a longer distance and the signal decreased, when less than a fixed value when the optical receiver at the receiving optical signal can not correctly identify signal encoding, will lead to error, so at a certain distance from the optical fiber transmission, with a fiber optic repeater, the light amplification the signal can support long-distance transmission, similar to the gas station.

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:Is the network repeater and the main route a signal or two signal?: This means that only the WIFI name of the primary route, which is seamlessly connected to the device, does not have to switch the signal, and if bridged, that is the two WIFI name,

Q:Which is good for a WiFi repeater?: Mainly to see if the link is stable and the repeater signal loss, repeater principle is that they will send a signal, when the connection after landing back switching relay mode (some more than repeaters used to relay) can find its own routing signal emission in the WiFi list, after the connection (to be renamed) to achieve the forwarding of the original signal in order to achieve, to enhance the signal propagation.

Q:Speed issues on wireless repeaters: If you want to expand the coverage, it is recommended not to use repeaters, buy two new wireless routers, set as main route WIFI name, the same as encryption, password, not the same frequency (1, 6, 11 recommended three completely nonoverlapping bands), close DHCP server (the main route have a DHCP server), the main route LAN port is connected with a new route LAN (not WAN). This will not cause interference or seamless roaming between the 3 routes, and the device will automatically switch the signal strong.

Q:Does the WiFi repeater really work?: Is still a repeater, is to be sensitive, the weak signal amplification as far as possible, the two is to high power, data communication is bidirectional, your repeater receives the ability, but was unable to return the signal to each other in vain
