Q:How to use a wireless repeater and wireless network card to make desktop computers online?
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.
Q:What is the difference between a router, a hub, a switch, and a repeater?
LAN switches have many ports, each of which has its own dedicated bandwidth and can connect to different segments. The communication between the ports of the switch is simultaneous and parallel, which greatly improves the throughput of the information. To further improve performance, each port can only connect to one device
Q:Can networks with master keys expand network signals with wireless repeaters?
Technically, it is possible, provided that the quality of the cracked network remains stable.
Q:M wireless routing repeater USD hole how to adjust the transmit signal
The input router management IP, log into the background into the wireless settings, all the settings must be guaranteed and the same set of relay routers; check the "open WDS", SSID and BSSID wireless router to input bridging (MAC address);
Q:How to make a notebook wireless relay
Are you going to put the computer into a router, download a connectify, there are 360 antivirus software, management software directly face a search there, under the name after the installation, set the password, if not set, a lot of online video tutorials, there are. Experts directly use the command to turn the computer into a router, but the novice is a bit troublesome, it is recommended to use that software
Q:In the fire alarm system, when will the relay module be used?
A lot of water indicators, ordinary 70 degree fire dampers. With input module, fire shutter door, fire smoke exhaust valve, cut off non fire electricity, sound and light alarm (now generally bus system), no need, general use control module or call input and output module. Multi line module for smoke exhaust fan, fire pump and spray pump
Q:How does the relay set up the connection WiFi?
You know his password and can log on, but the signal is weak, you can use the wireless router to set up a relay mode, you can zoom in on the wireless signal. That is, extending the coverage of wireless signals.Introduce a method to see, which can be used for reference.
Q:Can routers be plugged in after the relay is successful?
Please note that when you set up a router to open the DHCP server, the local connection of the computer should be set to automatically obtain the IP address.
Q:Differences between routers and switches and repeaters
Switches operate on the second layer (link layer), forwarding packets at the MAC address, and each port of a collision domain (collision termination) is itself in the broadcast domain. It can isolate the conflicts between ports and inhibit (not eliminate) the broadcast storm (after learning the address, no need to re broadcast).
Q:What is the function of the repeater in the automatic alarm?
In fact, far from the proposal of wireless transmission, many hosts can now support wired and wireless, generally 100 meters receive distance can be guaranteed, plus wireless repeaters can reach 1 kilometers
