Three routers were connected in parallel, and some of the machines were disconnected

A router has a WAN and a LAN address.

Recommended settings: a router: wan ip:

lan ip：

B Router: WAN IP:

lan ip：

c Router: WAN IP:

lan ip：

The WAN IP of Router B and Router C should be in the same CIDR block as the LAN IP of Router A.

The WAN IP of the B and C routers should be set to a static IP.

The gateway and subnet mask will be set up by yourself!!

Your last two routes are redundant in when the switch is used. This means that your setup is simply not necessary.

It is set like this: A route is the main one, and it is connected to WAN;

Route B connects the LAN of WAN to A;

Route C WAN to LAN of A;

The above is a normal connection and how to use routing.

Or according to yours, as a switch, then the B c route is not set (LAN), directly plugged in, and the computer IP is assigned according to the IP settings of the A route or filled in manually.

cgjvcd - Director Level 8 is the correct solution, it is very not recommended to set it up like you do, either as routing, segment management.

Either as a switch, plug in directly.

Just a small view.

If you want to use Route B as a switch or a hub, if you think so, you should connect Route B to Route A, and Route C to Route A, and Route A.

At the same time, it is also necessary to pay attention to whether the internal protocols of the router are set correctly, and static routes are recommended.

LAN IPs are not assigned well!

You didn't set it right, cgjvcd is correct.

1.Check whether the channels of the two routers are the same.

2.The router channel is "automatic" by default, and the channel of the two routers is set on the same channel for the stability of the bridge.

3.Is there an obstruction between the main and secondary routers, if there is an obstruction, it may be this problem, don't underestimate an obstruction, a steel and wooden door is enough to make the home router impenetrable.

4.Try to switch the positions of the two routers, DHCP on the router is to be turned on, you need to "enable", the address pool continues to be set by you, the gateway is required, and DNS is.

5.You check if the LAN of your 2nd router is.

How is the second route set up, how is the network cable connected, explain the connection and routing settings, I tell you**There is a problem.

Looking at the WAN port address of your first router, it seems to be cascading, strictly speaking, it is not a bridge (bridging is from the LAN port of the first router to the LAN port of your second router through the network cable). Here, it is best to fix the address, for example, that is, the WAN port of the second router is statically configured. DNS can still continue to fill in this is Guangdong Telecom, it seems that you are near Guangzhou-Shenzhen).

Like your connection mode, DHCP on the 2nd router is to be turned on, you need to "enable", the address pool continues with the gateway you set, the gateway is, DNS is. You check if the LAN of your 2nd router is.

Try enabling DHCP for the second route, and make sure that the CIDR block is not in the same segment.

If you copy the router B through the network cable connection.

1. Set the IP of Router B to DHCP (default). 2. In addition, use the driver wizard to reinstall the network card driver.

3. The wireless signal name is distinguished by the suffix A and B.

If your router B is bridging via wireless.

Reference: Wireless router bridging good search encyclopedia.

After wireless bridging, the secondary router can only use wifi, and the main router can connect to the computer to access the Internet.

After wired bridging, the main and secondary routers can be connected to the computer separately to access the Internet.

Solved because I'm like that too! You can try ab two router switching.

Disabling DHCP on the secondary route solves the problem.

It's not set up.

Router to wireless router, second router setup, 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.

A home router, right? DHCP requires different CIDR blocks.

It may be the cause of compatibility issues with two different brands of routers! Try to see if the Mercury router is directly plugged into the telecom network cable to see if the network will be disconnected.

Why Bridge a Wireless Router? The benefit of wireless bridging is that bridging can connect two users in different physical locations to the same LAN that is inconvenient for cabling. Wireless bridging can also play a role in signal amplification.

We can bridge multiple wireless routers together to achieve signal coverage.

Channel: (to be the same as the previous main router channel) Turn on the wireless function, turn on the SSID broadcast function, turn on the WDS function: scan the SSID of the main router, fill in the connection password of the main router, save, DHCP server:

Wireless bridging is best the same brand and model of routers, otherwise compatibility can only depend on luck.

There will always be some inexplicable problems with wireless bridging, and if possible, it is better to connect the two routers with a network cable, and Mercury's one will be used as a wireless switch.

Did you turn off the DHCP function on the Mercury router?

When bridging, you need to turn off the DHCP service of the secondary router.

Then the SSID of the primary and secondary routers should be the same, the channel should be the same, and the gateway address should not be the same, for example, the primary router is, then the secondary router is.

I feel that there is no problem with surfing the Internet, so I don't need to worry about the problem of ping or not, generally with the method I mentioned above, the wireless signal at home is a whole, and you can go to the Internet without resetting the link, but it is important to note that the secondary router must remember to set the wireless password.

I found out that the secondary router was open after 2 days of setting it up

Is there a "fixed" channel for the primary route?

The 2 ends of the network cable should be checked, and the network card driver should be detected, and the rest should be nothing.

Here's why:

1. Hardware. 1. Network card.

2. Connect the network cable.

3. The connection port between the router and the network card.

2. Software. 1. NIC driver.

2. Operating system.

3. Viruses. 3. Settings.

1. IP address setting.

2. Router settings.

Solution, itemized exclusion method:

1. Replace the network cable and change the connection port.

2. Uninstall the NIC driver and reinstall it.

3. Clean up system garbage.

4. Scan to remove viruses.

5. Set the IP address for the machine and reset the router.

6. Reinstall the operating system.

7. Replace the network card.
