Cannot connect to internet after updating to internet explorer 7
Before your computer can access the Internet, it needs to pass through the cable modem or router provided by your ISP.
A misconfigured or malfunctioning router will prevent all your devices from connecting to the Internet.
Next, we want to make sure that the network card is getting an IP address from a DHCP server and does not have a static IP address assigned.
To do this, click on Start and type in and press Enter.
If you are using a hard-wired connection, make sure the cable is plugged in fully into your router and computer.
Also, try a different cable in case there is a problem with the cable.
Windows does a pretty good job of determining if there is a problem in Windows that is preventing the computer from accessing the Internet and then fixing it, however, not all Internet problems are related to the computer.On some laptops, you have to press a key combination like Fn F5 to enable/disable the wireless card.
