The TP link wireless router cannot obtain a dynamic IP address

Actually, we are not good at this question, next time remember to tell us your network architecture when you ask. It's important whether you're dialing directly with a wireless router or whether the wireless router is just your wireless bridging tool.

If your routing is direct dialing, that is to say, you only have one router in the network, and the DHCP service of the route is enabled, if you can't get the IP you should check whether your network cable is abnormal, we will also encounter this situation, tomorrow is fine, today is not good, if it is connected by wireless, whether your computer has modified the key or other parameters of the wireless network, resulting in the computer can not connect to the wireless network, of course, it will not be able to get the IP. Finally, if you don't have any of the above, then you can right-click on the local connection and select Fix (each system is different, I mean XP here. See if you can get the IP.

If your router is used for wireless bridging, you need to turn off the DHCP of the route, and your wireless router should be connected to the existing network, remember, the access network cable should be plugged into the LAN port, the WAN port is redundant at this time, and only the existence of DHCP in the network can be automatically obtained.

I've run into this issue here as well, and just solved it. You try to turn off all the firewalls on the machine, my original windows firewall is turned off, but with Symantec's built-in firewall, I can get it after disabling Symantec, and then open Symantec and it can't, all of it is its problem. Good luck.

If you are dialing, you need to select PPPoe, then enter the account number, password, and click on the link.

Reasons why the wireless router cannot obtain a dynamic IP address and how to solve it:

Connect the network cable directly to the computer, check whether the computer can access the Internet normally, if not, it should be a broadband problem, you can find a broadband operator to solve.

2. IP address conflict: In most cases, the router cannot obtain dynamic IP address information because of IP address conflict. Solution: Change the IP address of the LAN port of the router.

In fact, many people have entered the setting misunderstanding, and the router only needs to fill in a few simple items to surf the Internet:

1. Choose according to your own Internet access: dynamic IP, static IP, PPOE, etc.

2. Set the bandwidth, password, and connection mode (time period connection, on-demand connection, always-on connection, etc.) in WLAN

3. Just connect, it doesn't matter with anything else! The default default of the private IP range is optional.

Note: It is best to explain the way you access the Internet, [At present, the most common broadband Internet access methods are ADSL (the most common), cable modem and cell broadband (development trend). In the eyes of the general end user, there is not much difference between them, but the connection between the user and the ISP is different, ADSL uses the ** line (** line to the home - cat - router), the cable uses the cable TV line, and the cell broadband (FTTX LAN) uses optical fiber and ISP connection. 】

You set it up to be static and try it and input the IP given to you by the operator.

A few days ago, I just bought TP-link, and the situation is similar to what you said, you can only go to Q, you can't open the web page, restart the route, and it can be used normally for a few hours, I asked the official website, the other party asked me to upgrade the software, and this situation has not occurred after the upgrade, but I still changed to a new route, after all, there is a shadow in my heart, and I can't think about it.

First of all, what network are you connected to? Is the router attached to the cat or to the first router? If it is connected to the cat, it cannot be set to dynamic IP, it should be set to PPPOE, and it is OK to enter the broadband account password.

How do you access the Internet If you can't get the dynamic IP of the secondary route, you can try the static IP and DNS can generally be on it, and you need to modify the LAN port IP can generally be changed to.

After the TP-Link wireless router is set up, it will not automatically obtain the dynamic IP, and the solution is as follows:

1. Check whether the connection status of the router network cable is correct;

If the router is set to dynamic IP to access the Internet, the WLAN port of the TP-Link router needs to be connected to the LAN port of the upper-layer router.

2. Check whether the router's Internet access mode is set correctly.

Open the router settings page, check whether to get dynamic IP address in the router network connection mode, and then confirm whether the network is the assigned dynamic IP address.

First check whether the DHCP service is turned on in your computer, and then check whether the DNS has an address in your network settings.

1. Check whether the WAN port indicator of the broadband line connection router is always on or flashing, if not, please follow the steps below to troubleshoot;

1.Check that both ends of the network cable are connected to the correct port and plugged in tightly;

2.Check whether the devices at both ends of the network cable are powered on;

3.You can try to change a network cable to try;

4.You can try to connect to other ports on the router, if only one port is not lit, it is possible that some ports are damaged.

2. Check whether the Internet access mode displayed in the "Management Interface-Running Status-WAN Port Status" of the TP-Link router is correct, and if not, follow the following steps to reset the Internet access.

Open the browser, enter the management interface to open the router, and enter the management account of the router "admin admin" in the pop-up login box.

If you can't open the management interface of the router, please check whether the IP address entered is correct or try to open it again, if you still can't log in, please refer to: What should I do if I can't log in to the management interface of the router?

Set the wireless name and password (this step is automatically skipped if it is a wired router):

3. If it is a PPPoe dial-up, please check the prompt of "WAN port status", click "View Help", and operate according to the relevant prompts (some routers do not have this prompt, please skip this step);

4. Some service providers may have bound a MAC address, please use a computer that can access the Internet before, log in to the management interface of the TP-Link router with wire, select "Network Parameters - MAC Address Clone", click "Clone MAC Address", then save, and restart the router according to the prompts to observe whether the router can obtain the IP address;

The network cable is not plugged into the WAN port, and there is only one WAN port, which is generally marked with a different color from the LAN port.

Do you mean router settings, generally you need to set the WAN interface to PPPOE mode and enter your home broadband account and password, so that the router can achieve automatic dialing, and then you will get the IP address.

If the settings are correct, it is necessary to consider the contact between the network cable and the router, and the network cable may be fine if it is replaced with a crystal head.

I suggest you ask the Great Wall broadband customer service, generally not lock the MAC now, they also allow customers to connect to external wireless routes, tell me about the situation, they will solve it. I'm a radio and television station, anyway, the customer service of radio and television is quite smart.

There are a few options in the router that you can try,1Copy the MAC address of the host.

It is to copy the MAC address of your computer to the WAN port of the router to deceive the upper-layer network, so that it thinks the router is your host and achieves the purpose of surfing the Internet. 2.Take a look at the WAN port settings, that is, below you change to dynamic IP, there will be some.

Mode 1, mode 2, see if there is, if there is, change it, but generally the first method can be successful.

Since the classroom computer can access the Internet, then it means that the uplink port is no problem, and the downlink is no problem, the only problem is that your computer needs to set the IP address, if you have to automatically obtain the IP address, log in to the router to see, whether the DHCP automatic IP address function is turned off, enable it, hope to adopt, thank you!

Change the connection method of your wireless router, connect the network cable from the landlord to the LAN interface of the wireless router, that is, the digital interface, do not use the WAN interface, at this time the wireless router is used as a switch, and you can use it directly without setting.

If your wireless router is a router or has an automatically assigned IP address. can be obtained automatically. The specific connection sequence is as follows.

1. Connection sequence, upper level - (WAN port) wireless router (LAN port) - computer.

2. On your computer, open the login router settings interface.

3. Network parameters, WAN port settings, account type, dynamic IP. Save.

4. If your wireless router is a cat, you need the following settings.

5. Network parameters, WAN port settings, account type, set to PPPoE, and fill in the broadband account password. Save.

6. Wireless settings, wireless basic settings, turn on wireless broadcasting.

7. Wireless settings, wireless security settings, and set wireless passwords (this is the password for connecting to wifi).

8. Save, restart the router, and you can receive the wireless signal after restarting.

Go into the router and see if it automatically obtains the IP address.

Nine! "State dynamic IP"., support mobile phones and computers, IP coverage nationwide, IP a lot.

Multi-IP regions.

2. DHCP is not enabled on the main router.

2. On the router's setup wizard interface, select the "Dynamic IP" option.

3. On the left side, select "MAC address clone."", clone the address, and click "Save".

5. Restart the router, under normal circumstances, you should be able to get the IP address at this time, and the Internet will return to normal.

Don't connect to the external network, enter the router, and then change the router management IP address as it turned out to be changed to etc.

Look at what I said, what do you do, don't move what I didn't say, don't set the wireless password before setting the route, don't connect the external line before setting the route, the wireless of the wireless route is turned on by default, don't move the computer to connect the network cable to the LAN port of the router, enter the routing interface, find DHCP in the menu is not enabled, save and then change 192 168 1 1 to 192 168 0 2 in the network parameters LAN port settings (this 0 and 2 can not have the same in the same network, you can change one in case of conflict) save, And restart the router, and finally connect the network cable to any of the 4 LAN ports of the route, the WAN port does not need 9, you have to change it back to the previous setting, it is best to restore it and reset it.

First of all, make it clear whether the router in your hand wants to be used as a switch or as a router. If the switch is used, then directly insert the network cable into the LAN port (any one of the four ports), and the remaining three ports can be connected to three computers, directly connected, and the IP is all automatically obtained. If you want to use the routing function, then please plug the incoming line into the WAN port, four LAN ports can be connected to four computers, and then turn on IE, enter the address or, some are.

Some are: The address of the router configuration interface of each manufacturer is different. After opening the interface, the username is generally admin, the password is empty or the same as the user name, after entering the configuration interface, click on the WAN configuration, change the address acquisition method to "dynamic acquisition", and then open DHCP, configure the address from, of course, this is determined by yourself, and you can restart it after configuration.

Is the IP address set in the IP protocol of the computer network properties to be automatically obtained?

After setting the dynamic IP address of the router's WAN port to surf the Internet, the IP address has been obtained, but it cannot be successfully obtained. This topic provides detailed troubleshooting tips for this issue that may be related to line connections, LAN-WAN CIDR block conflicts, service provider binding, and WAN port suitability.

The broadband line (home network cable or network cable from the modem) needs to be connected to the WAN port of the router, and the wired computer needs to be connected to the LAN port, as shown in the following figure

If the line is connected correctly, but the indicator light of the WAN port does not turn on, check whether the wiring of the WAN port is in poor contact and try to replace the network cable connected to the WAN port.

Log in to the router management page, and check whether the WNA port is a dynamic IP address in the WNA port in Running Status > WAN port status. If it is not normal, please follow the setup wizard to set up the router's dynamic IP network again. As shown below:

Connect the computer that was previously connected to broadband Internet access separately to the LAN port of the router (here it must be connected by wire) and log in to the management interface of the router.

Observe whether the WAN port can obtain the IP address after the router is restarted.

If the environment is a corporate LAN, hotel, rental house, etc., the IP address range used by the front-end network of the router is the same as that of the router, and the IP address cannot be obtained from the WAN port due to IP conflicts.

Solution: Log in to the management interface of the router, click Network Parameters, and change the IP address of the router to an IP address that is not in the same network segment as the LAN port in the LAN port settings (you can try, save and restart the router.) As shown in the figure below:

Due to the aging of the home network cable, the quality is too poor, or the line is too long, the line attenuation is too large, resulting in the WAN port being unable to obtain parameters. Try adjusting the rate and duplex mode of the router's WAN port.

Setup method: Log in to the router management interface, click Network Parameters > WAN port rate mode, select 10Mbps half-duplex or 10Mbps full-duplex mode in the mode setting, and then click Save, as shown in the figure below
