My computer is used in the local area network, and I added another computer yesterday, but I can t a

First, make sure that your new computer and your IP settings are the same

Subnet: Same, Gateway: Same, DNS: Same. If the computer you have access to the Internet is automatically obtained (DHCP) IP address, then take a look at the details in the support and fill it in.

Second, if the previous method does not work, it means that the NMS has settings, which may be set to disable IP or all MAC disabled. You can try it, set the computer that can't go up to use the IP that can go up now or the Mac that can go up (you need to emulate Mac software to change Mac,).

1. Use the K-Mac software to check the NIC number of the first computer.

2. Use K-Mac software to change the network card number of the second computer to the same as the network card number of the first computer.

Just reset the IP.

Telecom can set up automatic IP acquisition.

For Netcom, you need to fill in the IP address

It seems that resetting the IP will do the trick.

If the NMS locks the MAC address. If you have an extra machine, you won't be able to access the Internet.

Just ask the webmaster to lock your Mac as well.

There are many types of not being able to access the Internet. For example, the network card is broken. Poisoning.. There is a problem with the network cable. The IP is not set up, etc

First of all, if the network cable of the computer is connected to the router, look at the light of the router, the light of the corresponding interface is on, and there is a network connection icon on the taskbar of the computer (it cannot be a red cross).

If all the above conditions are met, then, first modify the IP settings of the machine (this is complicated, depending on how your router is configured).

First change the local IP to the same network segment as the router, for example, the router IP is, then the IP of your computer is modified to mean that this number should be greater than 1 and less than 255, and it cannot be the same as the IP of the other two computers in your home), the subnet mask is, the gateway is the IP of the router, DNS is automatically obtained, no need to set.

Click OK, then click Close, the computer will adjust the IP and connect with the router, if not, restart the computer.

If the IP of the router is, then the IP of the computer should be modified accordingly, the subnet mask remains unchanged, and the gateway is.

If you don't understand the above settings at all, and the other two computers can access the Internet without the above settings, then the router is automatically assigned an IP, and the computer IP is also automatically obtained. Restart the router and try it.

If the router has a firewall enabled and filters the IP address and MAC address, the above situation will also occur, but it is ......If you don't know how to configure a router, it can't be ...... for this reason

How to enter the router management interface: open the browser (any browser is OK), enter the IP of the router in the address bar (some are, some are, and then a login box appears, the account and password are admin, and then you can log in.

In addition, in some areas, broadband service providers restrict one broadband connection to multiple computers, and it is normal for them to not be able to access the Internet. Just ask.

Unicom 10010

Telecommunications 10000

Mobile 10086 (although I haven't seen anyone use mobile broadband, but it does).

It may be that the router connection is not very good, and the contact is not good.
