The newly purchased route cannot be dialed, and the router cannot be dialed

LCP (Link Control Protocol).

is a subset of the PPP protocol, in which the sender and receiver determine what information is necessary for data transmission by sending LCP packets.

The LCP checks the identity of the linked device and decides whether to accept or reject; determine the number of packet bytes that can be received in transit;

Check whether the configurations of both parties match, and if not, the link will be disconnected.

The data can only be networked if the LCP packet link is available. The LCP is responsible for the creation, maintenance, and termination of links between devices.

As can be seen from the system log, every time LCP stating, authentication failed (authentication failed), that is to say, your configuration does not match, resulting in authentication failure and unable to connect, the normal next step should be to get gateway IP (get the router address, that is, the gateway), get local IP (get the IP of this computer), got primary DNS address (to get the preferred DNS server), got the secondary DNS address (to get the alternate DNS server). What exactly should be configured, you can compare it with another normal router. If you can't find the reason, I'll 371067803

Please let us know the brand of your router and how you access the Internet (e.g. ADSL, Cell Broadband, etc.) so that I can tell you the correct way to set it up.

Install a wireless network card to use the wireless router.

Set up a dial-up account on the route, and directly work on the Internet to browse the Internet, without dialing the connection. Sometimes you can only go up to QQ**, and you can't open it, which is probably the reason for the incorrect DNS settings. Route settings.

Did you do what the instructions say? Do you unplug the router and use the cat to go directly to the Internet, or do you have the wrong username and password?

So sympathetic to Feifei! I'm trying my best to solve it for you!

Is it a poor network cable contact?

Possible reasons why the router cannot connect to the Internet with dial-up Internet access.

1. The router is not connected properly or the broadband password is entered incorrectly.

2. The problem of optical modem or the problem of the broadband hidden line of the guesser.

3. The operator's computer room has the problem of booting and preparing data.

TP-Link is cheap, but to be honest, wireless is really not powerful, it can be used for a while, but there will definitely be problems later! I also encountered this problem some time ago, and I used it well for half a year, and then suddenly I dropped the line wildly, until I couldn't dial the number at all! Then I sent it back to the manufacturer for a new one, and I arrived yesterday afternoon, but I still can't dial it!

I tried it at a friend's side, and it works!! The situation is the same as yours.

I read the solutions to the network overnight, but they didn't work, including setting up IP, gateway, DNS, MAC address cloning, binding IP and so on. Later, I found out that this is purely a defect in the product (it may be related to heat dissipation, external magnetic field, voltage, etc.)!

Later, I found another way, before using the wireless router, there was a line reason, I thought that since there is a problem with unlimited dialing, then use wired dialing, and then connect to the wireless router, the result is a try, you can get on!

Without further ado, here's how to fix it:

The wireless WAN port is connected to the wired LAN port.

Principle: The wireless WAN port and the wired LAN port are in the same network segment; The wireless LAN port and the wired LAN port are on different network segments.

Operation: 1Disconnect the wireless and wired routers first (it's important not to disconnect if you don't).

2.Use a wired or wireless connection to log in with a wireless router.

Network Parameters -> LAN Port Settings-> IP Address Settings > Save.

System Tools ->> Restart the router.

3.The wireless WAN port is connected to the wired LAN port.

4.(Supplement, it is recommended) that the network cable connected to the PC should be connected to the LAN port of the wireless router, because in this way you can log in,. That is, this allows you to operate both wireless and wired routers.

OK set up, let's take a look on the Internet.

Surfing the Internet with a router is not the same as dialing up a direct connection. It is automatically dialed through the router, so you need to set up the router first.

How to do it: Ah, a bit of a lot of words. You can check it out here.

Look at the prompt in the dialing log, it may be the wrong password!
