Recently, many friends are worried about this problem: the computer shows that the wireless connection has been connected, and the signal is very good, but you can't get on the network. Even if you can't get on QQ and ie, there are many reasons for this. Let me briefly introduce it below!
In particular, wireless routers are easy to encounter this problem; Let's check the problem that the wireless connection can't access the Internet:
Check whether the encryption password of the wireless network is correct. When we need to connect to the wireless network, we need to connect to the wireless network through the password. If your password is very long, it is easy to enter the wrong password. For example, the password with some spaces or characters is more error prone. At this time, we need to confirm whether your wireless password is correct. If it is not correct, we can't connect to the wireless network, Will not be able to access the Internet; You can disconnect the wireless network first, and then re-enter the password to connect.
The wireless router is bound with MAC address. If you set wireless MAC address filtering, you will not be able to access the network after replacing the computer or reinstalling the system or replacing the wireless network card, so you need to add a new MAC address.
The computer sets the IP address manually. If your network connection is a manual fixed IP address, it may also lead to such an error, because if the IP address you set is not in the same LAN as the IP address of the current router, you can't surf the Internet. Especially after some computers have been used in other addresses and changed places, you need to confirm whether the IP address of your network connection is correct. It is better to change the manual setting to automatically obtain the IP address.
If the network card driver fails, it's best to reinstall the network card driver, because this phenomenon will also be caused if the network card driver is not suitable for your network card. You can use the driver wizard to install the driver again or update it to the latest.
V: under Windows XP, you need to install WPA patch to support wpa2-psk encryption, so if the router uses this encryption and you haven't upgraded to XP SP3, please install kb893357 patch.
Conclusion: the analysis of wireless network connection but no network connection is almost these. Of course, there are some other unforeseen faults. For example, some compatibility problems.
