BleepingComputer.com: recovered laptop, now to find necessary drivers for networking

well i made a thread about a week ago, my laptop messed up, turns out it just needed a new harddrive. bought one, used a recovery cd to get regular programs and it is up and running now.
problem is, it doesn't have any networking drivers, so it won't connect to the internet. i am trying to save files on a flashdrive to transfer them over to my laptop but don't know the necessary drivers to get. i just want to connect it to the internet so that it can update all the other stuff by itself through Windows Update.
Anyone know where I should go and get drivers from?
My laptop is a Gateway mx6124. i tried a driver from their site, but it is all too confusing for me.

I am installing SP2, just to inform. I don't know whether it will update my drivers, but I am sure hoping it will.

Did you go HERE and enter the lap tops serial number?
