Why can t the laptop connect to the router backend machine?

Dialing is required on the router. Do not use a broadband connection.

Home Network Environment Cabling]:

1. There is a cat (modem): cat (modem) - router WAN port; The LAN port of the router --- a computer.

2. No modem: network cable --- router WAN port; The LAN port of the router --- a computer.

Computer enters the router]:

1. The computer IP and DNS settings are automatically obtained.

2. Open the browser, enter the general router address in the address bar is this or check the login information on the back of the router) Enter the route - enter the user name and password, (the default is generally admin).

Set Router Dialing]:

1. In the [Setup Wizard], select [PPPoE Dialing] (some are ADSL dialing), enter the username and password (provided by the network service provider) according to the prompts, and save.

2. In [Network Parameters] --WAN Settings], select [Normal Mode], and select [PPPoe Dialing] in the three options of [Connection]. The next step is to select [Auto Connect], Save, and Exit.

Your broadband operator doesn't allow you to open a second PC and only allocates you an IP.

The laptop can be connected to the router to surf the Internet, which means that you have set it up on the router, and then your desktop is directly plugged into the router with a network cable, and then the IP address of the desktop is set to "automatically obtained".

You can access the Internet, and you have to plug it into the LAN port.

It is estimated that there is a problem with the network connection of your desktop, in general, as long as both computers are connected to the router, even if they are not connected to the network, they can be connected to the local area network. It's no problem to even CS. So check your desktop network now!

Fix the network card settings.

First of all, connect the cable connected to the desktop to the notebook.,Okay, the network cable of the notebook is broken.,No, let's talk about it....

Then the laptop connection line is routed by the test ping, and the routing address can be found in the book of He Bangfeng, which is generally a pass, or a configuration problem....Check whether the automatic allocation function of the route is enabled, and whether the automatic acquisition function is set up for the notebook, and at the same time, check whether the DNS function of the notebook or the DNS allocation function in the route is enabled....

If it doesn't work, reinstall the network card driver of the notebook and try again, and if it doesn't work, find a twisted pair cable to connect the notebook and the desktop directly, test whether the LAN Zen is connected, and see if the network card of the notebook is broken....

Regarding wireless Internet access, the wireless key that needs to be configured for routing is the same as that of the laptop wireless network card, do you confirm that the configuration is correct and enable the wireless function of routing? By the way, there are two kinds of wireless signal encryption in wireless routing, the default kind of encryption is better, but some wireless network cards are not recognized, you can replace them and try it....

By the way, in addition, I've seen that some systems have problems, and you can't connect the route alive or dead, so you can reinstall it....

Also, the system has a service for wireless routing, go and see if it is turned off when the system is optimized...

By the way, you can disable the wireless network card first, and then let the wired connection work normally before using the wireless one....

Well, there is also to confirm whether your network is allowed to use routes, if not, don't toss internally, try to crack the route externally....

If you have any questions, you can ask me again, thank you, I like ** points....Thanks....

Did the desktop not cancel broadband autodialing?

Is the route set up to dial?

Whether the wireless network is encrypted, or can't be found, it may be that the signal is weak or the router has not turned on the wireless network or hidden, or there is a problem with the network card, or it may be a problem with the version, such as the network is, and the network card support is old, not supported.

If you can find a signal, you should be able to access the Internet.

This may indicate that the router is not set up correctly, and it should be set up again according to the instructions.

Does this book have wireless? Enter IP, DNS

The local connection attributes and IP addresses are automatically obtained.

Wait 5 minutes for the cable to plug in, then connect with broadband.

That's because your computer's network card drivers don't match.
