The specified IP address cannot access the Internet 30, and the specified IP address cannot access t

Surf the Internet in an auto-obtained way, and then use the following method to find out your DNS:

Click Start Run Enter cmd and press Enter, in the black window that pops up, type ipconfig all and press Enter, then you will see a line"dns servers..."The IP address behind is the address of the DNS server.

That's right, it's the MAC address is restricted, and the access to the super terminal is modified.

Hehe, the MAC address cannot be modified, it is solidified on the chip at the factory, and it is the only one in the world. If you want to modify it, you can only hyperterminal your switch up, but you may be limited because of passwords etc

Typical of the ARP virus.

You can set it up in the router.

The MAC address cannot be modified, just like an ID card.

There is no way to bind it.

Hello, you're a bit troublesome with this, it's better to restore the route.

Then you first see if there is a conflict of IP addresses when you change back to the original address.

If there is, it means that someone has temporarily used it, if not, you can log in to the route to try, because you can't access the Internet, it doesn't mean that you can't log in.

Because maybe the DNS server has changed.

If you can't log in to the router and there is no IP address conflict, it is most likely caused by you changing the MAC address of the network card. Optionally enter safe mode (with networking). Make IP NDS modifications here, and wait for the route to see.

If it doesn't work, then the only way to do it is to recover. There is no other way.

The steps of the method are as follows:

1. Open the local connection, right-click to select Properties, and select IPv4 settings.

2. Delete all the original manual settings, select Automatically get the IP address, and click the OK button.

3. After obtaining the IP address again, use the ipconfig command in the doc system to view the new IP address.

4. Open the local connection properties again, click Use the following IP address and use the following DNS server address, manually enter the IP address you just obtained, and enter the subnet mask, gateway address and DNS server address, and click the OK button.

5. Turn on the network connection to show that you can connect to the Internet.

You can cancel the MAC address you set.
