The network bridge can connect two different physical local area networks, it is a kind of storage and forwarding device that realizes LAN interconnection in the link layer. The Network Bridge receives the MAC frame from a local area network, after unpacking, proofreading, verifies, presses another LAN's format to reassemble, sends to its physical layer.
With the development of wireless network, more and more companies and enterprises have already started to layout wireless LAN, today we mainly introduce the wireless router bridging or WDS function suitable for small and medium-sized enterprises. This article takes Tp-link wr841n wireless router as an example, and sets up other router reference settings.
The image above shows a small business wireless network, A, B, c three departments if only 1 wireless routers are used, some computers may find that the signal is weak or unable to search for a signal, resulting in the inability to connect to the wireless network. The solution is: A, B, c three departments to connect a wireless router, three wireless routers through the WDS connection can achieve the perfect coverage of the entire region, eliminate blind spots.
Configuration idea: Wireless Router B as a central wireless router, wireless router A, C and wireless router B to establish a WDS connection.
The steps are as follows:
Basic settings for wireless routers refer to: TP Link Wireless router settings
One, center wireless router B setting
Login wireless router settings B management interface, in the wireless settings-Basic settings Set "SSID", "Channel", as shown:
Set up wireless signal encryption information in wireless settings--Wireless security settings
Record the SSID, channel, and encryption settings information after wireless router B is set, which is required for subsequent configuration of wireless router A and C.
Second, wireless router a settings.
1. Modify LAN port IP address. In the network parameter-lan port setting, modifies the IP address and the B router to be different (prevents the IP address conflict), like 192.168.1.2, saves, the router automatically restarts.
2. Enable the WDS feature. Once the reboot is complete, restart wireless router A with the changed LAN port IP address, and check "open WDS" in the Wireless settings-basic settings. We notice that the SSID here is not the same as the B router, of course it can be set to the same, so that you can roam within the three router coverage, that is, as long as you are at a random point within the scope of the network, to the other point in this area can also be connected to the Internet, do not have to reconnect, Re-enter the SSID is convenient to say that three routers make up a same large network.
3.WDS settings. Click "Scan" to search around the wireless signal.
Select the B router SSID number in the list of scanned signals, tp-link_841_b in the following figure, and click "Connect".
Sets the channel to be the same as the B router channel.
Set the encryption information the same as the B router, "save".
4. Shut down the DHCP server. At the DHCP server, select "Do not enable", "save", and restart the router.
Wireless Router A is configured to complete. At this point, wireless router A and wireless router B have successfully established WDS.
Third, wireless router C settings. The method set is the same as router a configuration (IP address must not be the same as router A, B, and other computers in the network), or it may cause an IP conflict the computer will not be able to access the Internet
