Tp-link Wireless Router WDS Setup method plot _ Wireless bridging settings

With the development of wireless network, more and more companies and enterprises have begun to layout wireless LAN, today we mainly introduce the appropriate for small and medium-sized wireless router bridging or WDS capabilities. This article takes tp-link wr841n wireless router Setup as an example, and other router reference setup ideas to set up.

As shown in a small business wireless network, A, B, C three departments if you use only 1 wireless routers, some computers may find the signal is weak or can not search the signal, resulting in the inability to connect to the wireless network. The solution is: A, B, c three departments each connected to a wireless router, three wireless routers through the WDS connection can achieve the perfect coverage of the entire area, eliminate blind spots.

Configuration idea: Wireless Router B as the central wireless router, wireless router A, C and wireless router B to establish a WDS connection.

　　The steps are as follows:

For basic settings of wireless routers, please refer to: TP Link Wireless router settings

　　One, center wireless router B settings

Log in to the wireless router Settings B management interface, set the "SSID ", " channel " in the Wireless settings-basic settings,

Set up wireless signal encryption information in wireless settings - wireless security Settings

Records the SSID, channel, and encryption settings information after wireless router B is set up, which needs to be applied in the subsequent configuration of the wireless router A and C.

　　Second, wireless router a settings.

1. Modify the LAN port IP address. In the network parameters-lan port settings, modify the IP address and the B router is different (prevent IP address conflict), such as 192.168.1.2, save, the router will automatically restart.

2. Enable the WDS feature. Once the reboot is complete, use the changed LAN port IP address to log in to wireless router a again and check " turn on WDS" in the Wireless settings-basic settings. Everyone notice here the SSID and B router is not the same, of course, can also be set to the same, so you can roam within the three router coverage, that is, as long as you in this range at random point to the net, to this range of another point can also surf the internet, do not have to reconnect, Re-entering the SSID it is convenient to say that three routers make up the same big network.

3.WDS settings. Click " scan " To search around for wireless signals.

Select the B router SSID in the list of scanned signals, such as Tp-link_841_b, and click " Connect ".

Set the channel to be the same as the B router channel.

Set the encryption information to the same as the B router, " save ".

4. Turn off the DHCP server . In 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, the wireless router C settings. The method set is the same as the router a configuration (theIP address must not be the same as router A, B, and other computers on the network, or it will cause the IP conflict computer to be unable to surf the internet ).

Router bridging (WDS) cannot be resolved from a secondary route (b-route, from routing) to the Internet workaround (DHCP settings)

Many students have already set up a wireless network at home, but because of obstacles such as wall blocks, so that the wireless signal attenuation is very strong, in order to solve this problem, I believe many students have begun to try to use Wireless bridge routers at home to expand the scope of wireless network
But many students reflect that the router bridge is successful, but still can only from the main route (a route) to the Internet, but not from the sub-route (b route, from the route) to the Internet, to find all kinds of tutorials, still can't solve,
Even some students made a few days did not fix, but also gas, but also helpless
This tutorial will help you solve the problem of router bridging, which cannot be routed from sub-routing
At present, most of the students bridge is using WDS----wireless distributed system to bridge two routers, this tutorial mainly for the WDS function, Brigde function This tutorial does not necessarily solve
It is understood that most of the students bridge the router method is either from the Baidu Library and other places to consult, or refer to the router instructions, according to my opinion, these methods are not paved, are not complete, these tutorials simply explain how to bridge the two routers, but did not solve the actual problem of the Internet
Many tutorials have this step: when you set up the sub-route (b route, from the route) is closed the DHCP server-----Dynamic Host Settings protocol (can automatically assign IP address to the device), so that all the devices connected to the sub-route can not get the IP address [some students open, but not set, So even if the IP address of the device is invalid]

There are two workarounds for the workaround:
1. Manually set the IP address for the device (cumbersome, not recommended)
Obtain the following information from the main route:
LAN port IP address for main route
Subnet mask for the main route (also called netmask, address mask, subnet matte)
The DNS server address for the WAN port of the main route, a total of 2
, take Tp-link router as an example

Set IP addresses for each of your wireless and wired devices

2. Manually configure the DHCP server for the secondary route (simpler, highly recommended)
Obtain the following information from the main route:
LAN port IP address for main route
Subnet mask for the main route (also called netmask, address mask, subnet matte)
The DNS server address for the WAN port of the main route, a total of 2
The DHCP server address pool for the primary route (start address to end address is called an address pool)
, take Tp-link router as an example

Turn on the secondary route DHCP server
Set the address pool of the sub-routed DHCP to a state with no intersection with the primary route
For example, the primary route is 192.168.1.100 to 192.168.1.199
Then the sub-route could be 192.168.1.50-192.168.1.99 or 192.168.1.200-192.168.1.225.
Address pool leases do not change
The LAN port IP address of the primary route is filled in at the gateway of the sub-routed DHCP, which is generally 192.168.1.1
The Default Field field is empty
Fill in the DNS server address from the primary routed WAN port at the primary and alternate DNS servers for the sub-routed DHCP

Save and reset the secondary route, and then connect to the sub-route to see if you can surf the Internet.

---------------------------------------------------------------------------------------------------------

The original understanding says:
A device that is able to surf the Internet must first obtain a valid IP address (consisting of an IP address, a subnet mask, and a DNS server)
The general primary route DHCP server is turned on by default, so devices connected to the primary route can be assigned a valid IP address through the primary routing DHCP server to be able to access the Internet
If a secondary routed DHCP server is turned off, a device connected to a sub-route cannot be assigned an IP address through a sub-routed DHCP server and cannot access the Internet
Even if it is turned on, the IP address assigned by the default DHCP server for the secondary route only applies to the Internet through the sub-routed WAN port, so this IP address cannot be connected to the Internet through the main routed Wan port, which is an invalid IP address
So we need to modify the DHCP server settings of the sub-route so that its assigned IP address can be connected to the Internet via the main routed WAN port.
Then the first IP address to the main route in the same network segment (generally as long as the last 3 bits of the IP address is not the same as the primary or secondary route)
Because the primary route is equivalent to a single server, the gateway is its own LAN port IP address, so the sub-routed DHCP gateway should satisfy the same LAN port IP address as the primary route
Next is the DNS server, the main route to the Internet and a condition is a valid DNS server address, generally through the WAN port dial or dynamic IP can get 2 DNS server address, one is the primary DNS server, the other is a standby DNS server
Then we also need to set the DNS server address for the sub-routed DHCP server, so that the IP address assigned by the sub-routed DHCP server can be connected through the WAN port of the main route, that is, the IP address assigned through the sub-route DHCP server is valid
This solves the problem of being unable to access the network from the sub-route.
