There are two computers in my home, which are connected through a router. The desktop can surf the Internet, but the other win7 laptop can't. There is no problem in setting DHCP on the router.

One: the desktop can be connected, which proves that there is no problem with the network.

Two: WIN7 notebook cannot be accessed, which proves that his IP address configuration is incorrect.

Solution:

One: check his IP on the desktop.

IP: 192. 168.0.5

Subnet: 255.255.255.0

Gateway: 192. 168.0.6438+0.

Domain name system: 202.96. 134. 133.

Modify the laptop WIN7 IP as follows

IP: 192. 168.0.6

Subnet: 255.255.255.0

Gateway: 192. 168.0.6438+0.
