The wireless router has a signal but doesn't even use the internet

1, set the IP address for "automatically missing

Different hotspots default settings are not the same, so if you set a fixed IP address may not be able to connect. Access to the Control Panel network connection options → wireless network connection → Click the right button to select Properties → set IP V4 protocol, XP under the TCP/IP protocol →IP address and default gateway/dns and so on are automatically obtained caries

　　2, whether the correct input password

Because of some input methods, you may add more than one space or use the wrong full-width characters, the router is sensitive to the case password, and so on will cause the connection. And when using WEP, four keys cannot be used at the same time, only one of them can be used. It is recommended that you use the copy and paste method when you want to enter the encryption key.

　3. Whether to use MAC address filtering

Some routers, although not encrypted but can not connect, then the router may use MAC address filtering, unless the use of software such as BT3 to sniff out the correct MAC address and camouflage, or give up. If you are building the network, then cancel the MAC address filtering try.

　4, check whether there is a signal problem

Place the router near the wireless card to see if there is a signal problem. Some routers signal quality is very poor, put away although the signal strength is good, but often unable to connect, in order to eliminate this weird things, you can put the router next to the notebook to try.

　　5, upgrade wireless network card driver

Wireless Card driver may be one of the root causes of the problem, more in the notebook and some foreign garbage, cottage wireless network card, because of the use of supporting a lot of drivers, may inadvertently installed wrong. This is often the case with Ubuntu, which can be solved by connecting multiple times or by ndiswrapper using Windows and even compiling the driver itself.

6, the network needs to verify the problem

Chinanet hotspots in telecommunications are available in many places, or are not encrypted. When searching the network, it is often connected, but not on the net, because further verification is required. For example, the telecom on this side needs to use the binding phone to receive the authentication code.
