In a wired and wireless network of wireless routers, the cable network part can use ADSL to access the wireless router normally, but the wireless network part of the computer is unable to share the Internet through no line.
This situation, you can consider the Wireless LAN network settings problem, you need to set the IP address of the wireless network card to "automatically obtain IP address."
Second, it may be caused by wireless router settings, such as a limited access to the computer, through the wireless router management page to the computer IP address and the port of the corresponding access restrictions. If this is the case, you can go to the management interface of the router, click Access Control on the left, and remove the IP access settings on the right.
However, there are times when you cannot connect to the Internet after you reset it, and you can restart the wireless router to try again.
