Laptop unable to connect to Internet

My daughter's laptop has previously been able to connect to the internet via our Belkin router. For the past few days she has tried to accesss the internet and has been unable to connect. We tried to reinstall the router on her laptop but still no luck. Do you know what could be the problem?

Check in Device Manager under Network Adapters for any yellow or red marks.

What CAMusing suggested is one possibility.
Another...
Go to Control Panel, then Network Connections,
Depending on whether you connect wirelessly or with a cable,
make sure the correct connection is "Enabled".
(these are usually labelled Local Area Connection, or Wireless Network Connection).

Then Double Click on the one you are using...
On the Wireless Connection, you should be able to view available networks. Make sure yours is listed.
Then, when you try to connect, you will need to enter login information.

If you are connecting via "Local Area Connection" and it is enabled, does it say that your cable is disconnected?
If so, try to plug the cable back in, both ends, into the proper connection.

At the router, make sure that the proper location is used to connect to your modem, as well as the proper connection to your computer.

If all of your connections are good to this point, then if you are using XP...
Start Windows Internet Explorer.
It should automatically try to connect, and if it is unable, then it will automatically run XPNETDIAG.
This will automatically repair many issues for you.

Let us know how these steps go for you, and if you still need help.

be sure to start the Windows Zero Config service
