2 computers connected to router but one can't get online

Hello Susan. If you flip your laptop around, there should be some text on the bottom that gives a more precise name to your computer. For example, mine is a Dell Inspiron M5040.

On your start menu task bar, to the far right is there an icon you can click with 5 bars indicating network connectivity? Click it and look for networks to connect to. Do you see yours? Make sure you are connected, and have entered the correct password to connect.

Also, type "network and sharing center" without quotes into the start menu search and click the top program. On the far left, click "Network Connections"". What do you see? Right click the wireless network connection and make sure it is enabled. Let me know how this goes

The newest driver for your wireless network is what I would recommend you use.

Alrighty... right-click on computer, and select "properties". Under "System", and under "model", it will list what your computer is. let me know

And I appologize, it is called "Change adapter Settings" in the network and sharing center, not "Network Connections" (though it links to this).

Your router shouldn't need a driver, I believe it should install its firmware automatically. If not, if you were to go into it, there should be a button to "update" or such. But no, I meant to use the most recent driver for your wireless adapter on your computer, which is why I've been trying to get your computer's name, so I can link you to the correct driver.

You are trying to use wireless right? Are you able to plug a Lan cable into the computer and use that to get online?

Ah. They don't have drivers listed for Windows 7, as it must be an older model. The closest you have to your version is Vista 32bit drivers. This is the dell website with the drivers. Look under "Network" for your drivers: Drivers and Downloads | Dell [United States]. To install and use them, follow this tutorial: Drivers - Install Vista Drivers on Windows 7 - by severedsolo

If you have trouble locating the drivers, click the link I gave you, and under "No", click "Choose from a list...", and then "Continue". Select "Desktop", "Inspiron", and then "530".

Uninstall all old wireless and other networking drivers before you install the new ones!

the network drivers. you can expand the list that says network.
