ASDSL Router Switch Connectivity Issues

Turn off the DHCP in the DLINK router, and then change his IP, don't be the same as the Tengda router, and set up each computer to automatically get the IP!

The question is simple:

1. The default IP of Tengda TE1618SK router and D-Link router can not be the same, the default is that you can change the default IP of one of the routers to: or both, 2. The 1st port of Tengda TE1618SK router --- your brother;

The second port of the TED1618SK router --- the WAN port of the D-Link router.

3. The modem is connected to the WAN port of Tengda TE1618SK, then the connection mode of the D-Link router is set to "connect dynamic IP" (do not choose PPPoE).

4. Regarding the way to obtain IP on the computer, if you are not familiar with the network and encounter the failure of not being able to access the Internet, I suggest that you set the IP of the computer to "automatically obtain IP" (note not to turn off the router DHCP, it is turned on by default).

5. Many people think that the router + router should change the network cable to a crossover line, but in fact, it is not necessary, and the current routers are intelligently corrected and connected, and there is no need to change it to a crossover line again.

Please follow my steps above to do, if not, pay attention to whether the network cable is more than 90 meters away from the signal and whether the crystal head is connected.

1 .As mentioned on the 1st floor.

2.If the problem is not resolved, it may be an issue with the network cable being too long. If the network cable is close to or more than 100 meters long, it is possible to make mistakes. If the quality of the network cable is poor, this distance is shorter. Let them swap network cables and it will be measured.

As shown below:

First of all, a router completes the routing of the external network (yours is dialing up or getting the address, depending on the way your hotel accesses the Internet);

Secondly, connect one or more switches under the LAN port of the router to extend the LAN port of the first router.

If it is a Layer 3 switch, you do not need the first router and directly use the switch to route the external network.

It is best to connect the WAN ports of the 24 routers on the 12th floor to the switch;

Here, the first router is the main router, and it must be able to access the Internet first;

Other routers set the Internet access mode as dynamic IP or static IP, and the router will automatically select it;

For dynamic IPs, you can obtain the IP addresses of the first router and route them by yourself, while you manually configure IP addresses for 24 routers (the addresses are within the IP address pool of the main router).

This one is troublesome, there are 12 floors. Although what you said above is not very clear, it should be so. As for the IP address, if your route is used as a switch, you don't need to change it.

The wire out of the main switch on the first floor is connected to the LAN port, and the other LAN port comes out and pulls up, and the IP can be ignored, unless you want to access the wireless device in the future, and give the device other IPs that are different from the gateway in the same network segment, DHCP must be turned off, and the wireless device can no longer be called a wireless router if you do this, it should be called a wireless AP or a relay.

And you'd better pull the wire from the main switch on the first floor for each layer, like the method you said is equivalent to layering the switch, divided into more than 12 layers, this method is not recommended, it is recommended to have a star distribution, so there are only two layers.

The LAN port of the router is connected to the switch, and the jumper should be through the line (the same at both ends), which can be 586A or 586B, and generally use the B standard: orange-white, orange, green-white, blue-white, green, brown-white, brown-white, brown-white.

Connect from any LAN port of the router to either port of the switch with a network cable (automatic identification of front and back lines) or UPLINK port (not automatic recognition).

In fact, the 10-meter network cable only needs to be 1-to-1 on the ground, and more than 10 meters can be used as you say (568B connection).

Yes, the most commonly used 568b connection.

Switches and routers how to connect methods such as years to change stupid:

Method. 1. Broadband connection - modem - wireless router - switch - computer. That is to say, some computers are connected through a switch, and some computers are connected directly from the wireless router.

Method. 2. Connect the switch in the LAN to another switch and then connect the router and computer. In other words, some computers are connected through a wireless router, and some computers are directly connected to the switch without a wireless router.

The wireless router sets the static IP address of the WAN port.

1. First, connect the home network cable to the WAN port of the router according to the manual, and then connect the LAN port of the router with the computer with the network cable. Turn on the computer, the IP address of the computer is automatically obtained, open the Internet Explorer, enter the obtained IP address gateway in the address bar: alternatively, enter the account and password admin (both are the same), modify the LAN port address of the wireless router, and prevent conflicts with the superior IP address by another network segment.

For example, change to. 2. After entering the route, select the setting wizard, and then select the connection mode of the WAN port and select the static connection, which is the IP address, subnet mask, gateway, DNS, etc. of the network segment of the higher-level switch; Then save! After the router restarts, go to Routing, select Wireless Network Settings--- Turn on Wireless, Turn on Broadcast--- then Wireless Security Settings --- you select the frequency band WEP, WAP WAP2, WAP-PSK WAP2-PSKIn any of these mid-bands--- just enter your own password!

Save --- restart routes! Get!

3. Note that your window7 wireless connection must match the frequency band you choose, otherwise you won't be able to access the network even if you connect!

Maybe I'm afraid of leaving which equipment or which network cable when moving, right? Unless this switch supports VLAN, it won't be such a toss-up.

Normally, different ports of the router will not be connected to the same switch.

It doesn't seem to have much effect. If you want to connect with each other, it doesn't need to be that complicated.

The switch is usually a Layer 2 device, first of all, you should not assign IP to the port of the switch (that is the work of the router), all the devices under the switch port (in the case of no VLAN division) are in a local area network, and the route from PC0 to DNS in the figure only needs a default gateway! I don't know if you can understand that?

To correct the statement of 1l, if it is only the connection mode in the figure, your router does not need to write a static route, but the gateway of your PC0 should point to the router interface address connected to the switch on the right, and the gateway of DNS should point to the router interface address connected to the switch on the left!

Make sure that the router is able to ping PC0, if so, there should be a problem with the router's routing configuration.

Please reconfigure the static route on the router to configure two commands:

ip route dns address dns mask ip route pc0 address pc0 mask port address on the right side of the route.

If the switch is not configured in any way, you can see it as completely transparent and can be ignored.

As I said upstairs, just add the network segments at both ends of the router to the router.

You'll have to write out your configuration to find the problem.

If it is an 8-port router, you can do any settings, connect the network cable pulled out of the switch and the network cable of each computer to the LAN port of the router, you can do it, if it is a 4-port router, then you need to connect the network cable from the switch to the WAN port of the router, set up relevant data, and connect each computer to the LAN port of the router.

Hello landlord:

You connect the network cable directly from the switch to the router.

The lan port of the device is fine, that is, any of the ports marked with 1234 you said.

Router Settings:

1. Connect the LAN port of the router with a computer, open the browser, and enter the IP address, username and password on the back of the router to log in to the router management page;

2. Find the wireless settings page, turn on wireless, select WPA2 encryption, and set the connection password to save;

3. Open the DHCP page and close the DHCP service.

4. Restart the router, OK.

I see, you probably use the broadband service provided by cable TV, which varies from region to region. Generally speaking, in terms of the services provided by cable TV on my side, HFC (abbreviation of Hybrid Fiber Coaxial, which is a hybrid network combining optical fiber and coaxial cable) was used to provide cable TV analog signals, but now the infrastructure has not changed, and it has changed to transmit digital signals, and at the same time can provide Internet services. Therefore, they generally say that it is fiber-to-the-home (in fact, at most, optical fiber or coaxial cable to the building) and then change the data packaging to Ethernet (Ethernet) through the routing and switching equipment, and connect it to your home (commonly known as LAN, local area network, local area network). It is impossible for you to use fiber optic access at home, the reason is very simple, the equipment is expensive, the maintenance is complicated, even if it is connected to your home, your desktop and laptop do not have fiber optic modules, and they have to be converted into Ethernet signals (that is, the interface that is larger than the ** line), of course, this refers to the ordinary computers that are usually bought on the market.

Then let's analyze these devices in your home, the yellow line should be all the data signals provided to you by cable TV (including the ones you use to surf the Internet and watch TV), because your switch is a layer 2 device, so, he will assign these signals to your router and set-top box (I guess these two should work at the network layer), and then the router handles all the traffic related to your Internet access, and the set-top box handles all the traffic related to TV, The switch should act as a splitter or hub. Therefore, the connection method should be like this, the yellow line is connected to the switch, and then the two gray lines are connected to the Internet port of the set-top box and the router respectively, and the 1234 port of the router can be connected to your desktop or laptop (of course, you can connect to the wireless if there is wireless), I guess that cable TV should give you a username and password for Internet access, then you should dial up the Internet, so, after your computer is connected to the router, you should set up pppoe dial-up, and fill it in with your username and password. Ask again if you have questions.

The network cable drawn out of the switch can directly access the Internet without dial-up?

Network - Cat - Router - Computer.

Network - Cat - Switch - Computer

Either method is fine.

This kind of connection, the router can only be used as a switch, when you connect, pay attention to only use the port marked as LAN on the router, don't be wrong, otherwise it won't work.

Set a private IP address The gateway to the switched machine is the IP address of the switched port.

You look at what the IP of the switch is. In the description or on the back of the switch, the computer IP is set to the first 3 segments and the switch is the same, and the fourth segment is different. The gateway is set to the IP address of the switch.

Generally, the IP address of the switch is OR.

Generally speaking, the DHCP of the router is enabled by default and can automatically obtain the IP address.

If you want to set it to static, the gateway of the router is generally OR by default, that is, the IP address of the router, of course, you can also set it yourself.

You can set the IP address of your computer to or to, but don't have the same one in the network, otherwise there will be a conflict of IP addresses.

Typing word by word, absolutely original, very hard. Hope it helps.

Kindness. Now you need to convert the IP to operate.

Go to the next IP software. Kyushu IP。。That's it.
