My wireless internet on my laptop wont work, please help

Hi =] I have a Dell Vostro 1500, and I recently re-installed Windows Vista on it. I installed the drivers from the Dell CD that came with my laptop, along with the utilities. But my wireless won't work, it says the driver isn't installed =[ But I installed all the drivers that CD told me to.

These are the utilities I installed:

Dell OS Tolls Rev:A00

Dell Notebook System Software Rev:A00

And these are the drivers I installed (a check mark showed up next to them indicating that a hardware scan had detected the device):

Intel Mobile Chipset Rev: A05

Ricoh R5C833 Rev: A00

Conexant D330, HDA,MDC,v.92,modem Rev: A01

Broadcom 440x 10/100 Integrated Controller Rev: A03

Intel Matrix Storage Manager-Notebooks RevA02 (this one extracted, but didn't instal and I don't know if thats what it was suposed to do?)

Intel Turbo Memory Rev: A00

Intel GM965 Express Chipset Family Rev: A02



Did I not instal the correct driver? Is the driver I need not on that CD? Please help.

 

Okay, so I found this Dell Multi Device Driver, and I read that that would fix my wireless problem. But when I go to install it a setup error occurs, and says:

"The operating system is not supported. The software will not be installed. Setup will now exit."

Soo, now what? My OS is Windows Vista Basic, it came on my laptop. So I'm confused, is this not the right driver?

-EDIT-
I got it! =D

 

Go to the Dell Support site for your model and look up your machine by Service Tag. You might have the DELL or the Intel wireless. Look it up, then install the appropriate driver under Network:

It looks like they offer only 2 different wireless Drivers, you can also just try each one.

 

Yes, exactly like TheStar says, and anytime you reinstall the OS, you must understand the Drivers CD is already out of date.
You must update all the drivers if possible.

Also, open Device Manager and see if there are any "yellow icons" present.
This means there are some physical devices that do not have properly configured software drivers or .inf files present in the OS.

Always reintall ALL of your devices so everything flows together seamlessly.

One yellow icon in the devices means there are problems and it may very well effect the most basic part of your computing needs.

Good Luck
