Q:Why can't the phone be found in the WiFi network that is set up by the computer? Network attributes can be seen, how should we correct?
First, see if the router version is consistent with the authorities! Then download the official firmware import upgrade, according to the official brand model upgrade guidance file upgrade, usually download firmware, loading and upgrading operations on the router management page! If you have third party firmware, you'll have to upgrade to the uboot, provided you haven't changed the uboot, and first set the fixed IP address that is different from the routing management page! If the router management page is 192.168.1.1, then the 192.168.11 mask is set in the IPv4 protocol to save for the 255.255.255.255! Unplug the WAN port and only keep the Lan cable. Unplug the power line and hold the reset button for 3 seconds. If the indicator flashes, it has entered the brush mode, opened the browser, entered the router, managed the IP, and loaded the firmware after the access to the admin page!
Q:Request WiFi repeater settings, I do not know the other router's model and password, but I know the WiFi password!
Close your router DHCP service and note that the two routers cannot be the same gateway. Commercial router settings method: your router MAC address, such as the other router, and then the other router MAC address, such as your router. Close dhcp. Gateways can not be the same. Restart your router after you have finished setting up
Q:Should the two wireless routing be chosen as a relay mode or a bridging mode?
Of course, in the strict sense, the two are also different. When using relay mode, the network SSID numbers are the same, while in the bridge mode, the network SSID number is different.
Q:How can I find the coverage area of repeaters?
(1) types of repeater stations for mobile communications;From transmission signals, there are GSM repeater and CDMA repeater station;--- from the installation site to outdoor machines and indoor machines;--- from the transmission bandwidth, there are broadband repeater and selective frequency (selective channel) repeater;--- from the transmission mode, there are vertical repeater, fiber transmission repeater and frequency shift repeater. ?(2) the type of mobile repeater;GSM mobile communication repeater stationGSM mobile communication repeater is a way to solve the blind spot of the base station coverage. The erection of the repeater can not only improve the coverage effect, but also greatly reduce the cost of the investment base station.GSM repeater is a communication device designed to eliminate the small signal blind area or weak signal area of GSM900MHz/1800MHz band mobile communication network. Blind signal is widely used in underground shopping malls, parking lot, subway, tunnel, high-rise buildings, entertainment, office or private residential elevator cannot reach the base station signal, but also has a fairly good coverage for the elimination of weak signal district city due to the impact of the edifice of several rural outdoor local signal shadow Yin the side or outer zone.
Q:Do you need the same brand as the WiFi router using the WiFi repeater?
If you already have two routers, the brand is different, you can try, so as not to waste.
Q:What is radio relay and how to use relay?
Repeater (RP) is a device that connects network lines and is often used for two-way forwarding of physical signals between two network nodes. The repeater is the most simple network interconnection equipment, mainly to complete the physical layer, is responsible for the physical layer of two nodes according to a transmission of information, copy, adjust and complete the signal amplification function, in order to prolong the network length.
Q:What is the principle of fiber repeaters?
Optical fibers use optical pulses to transmit information along the optical line, instead of using electrical impulses to transmit information along the cable. At one end of the system is the transmitter, the starting point of the information to the fiber line. The received electronic pulse information of the transmitter is derived from the copper wire cable, and then the information is processed and converted into an equivalent coded optical pulse.
Q:Is the repeater good for amplifying signals or good for routers?
Distance can be used short relay 3, slightly by
Q:My routing repeater, I want to hide my hot spots, hide ssld, show this
It doesn't matter much, because WPS is sometimes not safe and people can run pin code to crack it
Q:How does the relay link to my desktop computer?
The connection between the wireless AP and the normal network is the converter, which can be purchased at Taobao. Also, the AP cable on the receiver side is connected to the wireless WIFI (wireless router).If the distance is no more than 50 meters, you can buy an enhanced version of the wireless router.
