I cannot connect to the internet, what could be the problem?

The problem might be:

1. Physical connection problem
2. Internet browser’s “Internet Options” setting
3. DNS error
4. Router cannot establish connection with ISP

1. It could be the connection between your PC and the router/modem which cause this problem. Check the connecting media (wired/wireless) and consider replacing the network cables with new ones.

2. Check your browser's connection settings for any errors

3. Sometimes it could be a DNS error, where you are still able to access internet services such as Windows Live Messager or Yahoo Messenger service , but you cannot surf webpages. You can try restarting the router or setting a static DNS server address for your PC to solve this issue.

4. There may be some configuration errors in the router to connect to the Internet. Check the router's configuration again or contact the vendor for assistance.
