- If you are using a router, please try pulling the power cord out for 10 seconds and plug it back in. A router basically splits your Internet connection between multiple computers and may also provide wireless Internet access. If you still cannot get online, you will have to bypass your router and any other networking equipment so that the cable modem is directly connected to a single computer. If you bypassed your router and still cannot get online, or you do not have a router, please see the next step.
- If you are using a firewall program such as Norton Internet Security, Norton personal Firewall, McAfee Internet Security or McAfee Firewall try lowering the security settings or disabling the program. If you are running Windows XP or Windows Vista, you may have Windows Firewall enabled. To disable Windows Firewall in Windows XP, go to Control Panel followed by Network Connections (or Network and Internet Connections). Now right click on Local Area Connection and select Properties. Click the Advanced tab, and remove the check from Protect my computer and network by limiting or preventing access to this computer from the Internet. To disable Windows Firewall in Windows Vista, go to your Control Panel followed by Security on the menu on the left. Click Turn Windows Firewall on or off on the right side of the screen. Now check if you can get online. If you do not have a firewall program running, or you still cannot get online, see the next step.
- What is your Local Area Connection status? To check this in Windows XP, go to your Control Panel followed by Network Connections (or Network and Internet Connections). Now double click on Local Area Connection and look at the status. If it says connected, go to the next step. If it says Disabled, click the button at the bottom of the window that says Enable. If it says Limited Or No Connectivity, go to the next step. If it says "Network Cable Unplugged" you may want to check the Ethernet cable plugged into the back of your computer and the back of your modem. Try replacing the network cable.
Try repairing your connection. To do this in Windows XP, go to your Control Panel followed by Network Connections (or Network and Internet Connections). Now double click on Local Area Connection and click the Support tab. Click the Repair button.
