1. Check if the password is wrong

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

2, the wireless router has been and MAC address binding

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

3, the service set is completely correct

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

4, the assigned IP address is set correctly

Wireless networks use manually assigned IP addresses and DNS addresses, which are required to be set in the wireless connection properties under Windows. Windows and Linux are not the same, you can not set different IP addresses for different wireless networks, so when switching between multiple wireless networks, it is easier to use a manually assigned IP.

5, the driver is suitable for the current network card

Most of this happens when you first use a wireless card, and if you use Windows 7, you will normally automatically download and install the correct NIC driver. However, in extreme cases, the download driver may not be suitable for NIC use, so it is possible to download the driver from the manufacturer's homepage.

6, the necessary patch is installed well

Under Windows XP, you need to install patches to support WPA2-PSK encryption, so if your router uses this encryption and you haven't upgraded to XP SP3, install KB893357 patches.

7, if here can detect and repair the fault is the best, however, if the repair system, still can not surf the internet, then we go back to the network and Sharing Center, to find changes to the wireless network card properties, and the right key wireless network card properties, find the IPV4 protocol, the current network for manually configured IP address, change set to " Automatically get IP address.
