There is a problem with the line by connecting again to a wireless router, DHCP.

If you have a line before the wireless router, it is recommended that you set it as follows:

The existing line is A, and the wireless route is B

2. Route B does not automatically obtain IP, that is, dynamic IP, so that the IP allocation rule of route B is subject to route A.

3. If you are afraid that the wireless signal of Route B will be stolen by others, you can set wireless encryption or MAC binding in Route B, which will not affect the use of the entire network.

DHCP routing IP conflict, first connect to the wireless router to turn off DHCP and then change the IP of the wireless router to it, and then connect the network cable with the line to the LAN port of the wireless router, and the computer can also be connected to the LAN port.

Since DHCP has been set on the wireless router, its settings are valid for wireless wired. Therefore, even if the signal can be detected, the IP address cannot be correctly assigned, so it is natural that you cannot access the Internet.

1. There can only be one leader (DHCP) in a network, and the two leaders will conflict (which is big?). ）

2. The wireless network card also has a MAC, is there a set IP bound to the wireless MAC? It's best to turn off DHCP for wireless routing. The IP of the wireless LAN is changed, too, and it cannot be the same as the IP of the wired LAN.

Because the DHCP function is enabled on the primary router, after the bridge, the actual gateway of the network is the primary router, and the secondary router only plays the role of a switch.

Because the DHCP feature is enabled on the primary route, the actual gateway of the network is the primary route after the bridge. At this point, the secondary route only acts as a switch. If the secondary router also has DHCP service enabled, it will cause two gateways to appear in the entire network, causing chaos throughout the network and thus making it impossible to access the Internet.

DHCP (Dynamic Host Configuration Protocol) is usually used in large LAN environments, and its main role is to centrally manage and allocate IP addresses, so that hosts in the network environment can dynamically obtain information such as IP addresses, gateway addresses, and DNS server addresses, and can improve the utilization rate of the address.

If the DHCP service is also enabled on the secondary router, there will be two gateways in the entire network, resulting in chaos in the entire network, and the Internet cannot be accessed.

First of all, you can choose to turn it off or not! As long as the gateway in DHCP can be set as the LAN address of the main router, it can not be turned off, at this time, the DHCP of the secondary router can be enabled, and the interval is staggered with the master, but the gateway must fill in the main LAN address, and because some models of Tengda's router DHCP can not specify the gateway (it should be the LAN address of the router connected to broadband), the default is its own LAN address, if DHCP is turned on as a secondary router, The gateway assigned during IP assignment is the secondary router LAN address, which is wrong, the device cannot access the Internet, and there is no way but to turn it off at this time! In order to bridge based on such situations, it is generally recommended to directly close the DHCP of the vice! It's just a hassle to set up, but it doesn't have to be absolutely!

After the two routers are bridged, it constitutes a local area network, as long as there is DHCP service on the local area network, no matter in **, the device can get the IP provided by connecting to the local area network! If there are multiple DHCP service sources, the IP will be randomly obtained from one of them! Under normal circumstances, after the primary and secondary bridging (wireless bridging and the interconnection of the LAN ports of the two routers, this wired bridging is the same!)

As long as you can connect to one of the routers in one of the signal ranges, you can get DHCP service!

The above point is theoretical, but in fact, due to the defects in the system software implementation of the manufacturer's WDS, some smart phones can not get the IP from the master when connecting to the WDS sub-router, and the solution at this time is 2: one is to turn on the secondary DHCP. The second is to manually set the IP of the device

If you use AP mode, you must turn it off, and if there is a conflict, you don't need to use the route mode, and you can change the IP segment of the secondary router.

DHCP is disabled for the secondary route, and the received address is the address of the primary route....Use the secondary router as a switch....

DHCP can be turned on, the secondary router connects to the main router through a static IP, and the secondary router remembers to plug in the WAN port.

I don't know, you go ask the router.

A wireless router needs to be turned off when a normal switch is in use.

Enter the wireless router management interface, turn off the DHCP function, and plug the network connected to the main setting directly into any 1234 port of the LAN port.

Second, if the wireless function is used, it does not need to be turned off.

The second router is set up differently than the first, and the main reason for the restriction is the wrong setting.

Here's how to set up the second router:

1. In connection mode, lead a network cable from either LAN 1234 port of router A (main router) and plug it into the WAN port of router B.

2. Enter the web management interface of router A, open the LAN port settings - network parameters, and check the IP of the LAN port, assuming that it is.

3. Modify the IP address of the B LAN port of the router.

If the IP address of the LAN port of Router B is the same as that of Router A, the IP address of the LAN port must be changed. For example, change to.

4. To modify the WAN port settings of router B, click WAN port settings and set the WAN port connection type of router B to dynamic IP

Then save. In short, the main router remains the same, and the LAN port of each new router is changed to a different one, and other settings are the same.

5. Set the wireless password.

Try to make the password as complex as possible, preferably a mix of numbers, English, and symbols.

The IP address of the computer is set automatically, so I can't log in to the management page of 710? The setting is fixed, right?

The two passers can be bridged or connected. The bridging is wireless, the connection is wired, and the connection is also divided into parallel, and cascade. Here's the bridge for you.

If you need to connect, I'll introduce you. The parallel connection is from the LAN port to the LAN port, and the cascade connection is from the LAN port to the WAN port.

Theoretically, the secondary route does not have DHCP enabled, and it is the function of DHCP implemented by the primary route through the secondary route, but many people have encountered that there is no such function. You need to manually set the IP address of your computer.

There are also people who are insiders, the secondary router is set to turn on DHCP, but it can't be duplicated with the main route, generally if the main route is turned on 100-149, the secondary route will be turned on 150-199, (only the last three digits are said), anyway, it does not overlap. In the DHPC service, you also need to fill in the two DNS of the WAN port of the main router, and fill in the IP (192168 of the main router) of the gateway

Hope it helps!

Landlord, if you are connected to the LAN port, there is no conflict between the IPs of the two routers you set, and you will indeed encounter the situation you said. You can enable DHCP, the start and end of the secondary router, as shown in the diagram above. 150-199, the gateway is also the same as above, DNS is filled in the gateway, that is, the 16819211, the standby DNS is empty, so it's OK, if you want to be perfect, the main router's enabled DHCP is 100-149, as shown in the figure above, just change this, pay attention to save.

Give it a try!

"If the DHCP server is not opened, I can't log in to the management page of 710" - wrong, whether I can log in to the management ** has nothing to do with DHCP. But for example, if you have changed the IP gateway of the route, the IP of your computer will naturally become the same, and you have to enter it.

LZ: What you said about "bridging" is a bit vague, is it bridging through wireless WD, or connecting the 710 to the network cable and the 340? There is a difference between the two methods, the former is indeed a bridge, and the latter just uses the 710 as a switch. But both works fine.

I can't be sure which LZ is talking about, but either way, you'll have to change the IP inside the 710.

As we know, each router has a management page address, which is actually its gateway, which is generally the default gateway of the above 340 and 710, if it is bridged at will, it will lead to IP conflicts and cause all network disconnections. So what you have to do is set the IP of the 710 to, (0 is not a certainty, but 0 is generally used), and then turn off the DCHP of the 710. You can set up the things in 710 before connecting 710 with 340, and then connect to 340, and the route will be mediated by yourself.

If in doubt, you can contact me Q, 452335051, Yang.

The default address of the TL-WR710N is to manually set the IP address of the computer to connect to the TL-WR710N, and you can log in to the management page of the TL-WR710N.

It would be nice to have two routers on different channels.

Modify the IP range at the same time.

One setting. Another one.

Set up the two routers in different network segments.

DHCP assigns an address to a computer.

When DHCP is disabled, the computer cannot obtain the IP address and cannot log in to the router interface. In order for a computer to access the Internet, it must pass through the first gateway. If DHCP does not have an IP, subnet, or gateway assigned, the router cannot be accessed, and the network cannot be connected through the routing WAN port.

2. Enter the gateway to log in to the router interface in the [address bar] of the browser.

If DHCP is turned off, an IP address will not be assigned, and the router with DHCP turned off cannot be accessed from the computer. If you want to reset it, press the reset button to go to the factory settings, and then reconfigure it.

If the DHCP of 710 is disabled, you need to manually set the IP address of the computer to 710, because the default address of 710 is the address of the same network segment to access. After manually setting the address, you can connect with the 710 separately with a network cable and log in to the 710 management page.

Your first concern is not DHCP, but to turn off the routing function of this wired router.

The second is to turn off the DHCP of the wired router.

Within this broadcast domain, the wired router exists only as a secondary switch.

DHCP for the wireless router should be turned off and the first router should be used as the primary router.

Take a look at the intranet IP of the wired router on the computer, whether it is automatically obtained, and use manual ps: lightning ice cream This netizen, he uses LAN as a switch.

ps: ccmung this netizen, he uses the parallel mode, and you divide the network segment two routes into series.

Do not use one routing address in one network segment. A set. It's good to keep it separate.

WAN—LAN connection, open connection, disable DHCP.

Wireless router to wireless router, the second router is set up, there are two ways (provided that the first router has been set up):

The first method: dynamic IP mode (the first route is the primary route, and the second route is the slave route).

1. Plug in the router and do not connect the LAN port of the main router first, and reset the slave router (restore the factory);

2. Connect the computer from any LAN port of the router to enter the settings page;

3. Set according to the dynamic IP;

4. Then set the SSID, encryption method and password;

5. Save and restart;

6. After setting, connect the network cable from the LAN port of the main router to the WAN port from the router.

The second method: wireless AP mode.

1. Connect the computer to the LAN port of the router first, and change the IP address of the slave router. For example, most router addresses are, we just need to change from router IP address to that;

2. Turn off the DHCP function from the router in the settings;

3. Finally, connect the network cable from the main router to the LAN port of the slave router (any one is fine), note that it cannot be the WAN port.

Basic Router Setup Tutorial: A Detailed Introduction to DHCP Functions.

DHCP is a dynamic IP address assignment, after turning on this, your computer will automatically connect to this router and configure your network card to automatically obtain you can surf the Internet.

The server can be seen below with several computers in use.
