Solve problems with wireless network connection but not on the internet

1, check the password is wrong

Enter the wireless connection password, if the password is longer may be wrong password, so we recommend you enter the password again. If possible, enter the password directly using copy-and-paste. When copying and pasting, be careful not to select extraneous characters yo, add one or two more space is the most common error.

2, the wireless router is bound to the MAC address

In order to prevent others from rubbing the network, many home users have set up the wireless MAC address filtering, but when the computer or wireless card replacement, it will not be on the network, so you need to add a new MAC address in the router settings.

3. Check Service Setup Issues

Checking the computer-side service settings, such as DHCP Client, Wirelesszero Configuration service does not start, will cause the wireless network to be used abnormally. Where DHCP is not turned on, computers that use auto-assigned IP cannot automatically configure IP addresses.

4, check the manually assigned IP address

Wireless networks use manually assigned IP addresses and DNS addresses, which need to be set in the wireless connection properties below Windows. Windows and Linux do not have different IP addresses for different wireless networks, so when switching between multiple wireless networks, it is easy to get to the network if you use manually assigned IPs.

5, the wireless card driver is not correct

This is most often the first time you use a wireless card, if you are using Windows 7, you will generally automatically download and install the correct network adapter driver. However, in extreme cases, the downloaded driver is not necessarily suitable for the NIC, so it may be necessary to download the driver from the manufacturer's homepage.

6. Check if WPA patch is installed

Under Windows XP, patches need to be installed to support WPA2-PSK encryption, so if the router uses this encryption and you have not upgraded to XP SP3, install the KB893357 patch.

Wireless network can be connected, but not on the network fault check on the above steps, but may be good for a lot of other reasons, Nic driver incompatibility may lead to network connection, but not on the network.

Ask:

So I would like to ask ....

Guide me in some simple and clear language ..... Don't get me, I see myself dizzy ....

Emphasis: The computer is vista ....

Thank you!

A: In the properties of your wireless card configuration of TCP/IP properties, found in the DNS, player settings, give you two Beijing dns:202.106.0.20,202.106.196.20

After you can surf the Internet, look for your local DNS to set it in.

Of course, if you want to solve the problem, it's best to set up DNS in the routing.
