Thanks, will do and show you.
I am pretty green at this, and i don't have access to broadband, downloads through regular internet connection is pretty unreliable, most of the times the download are at the rate of 9KB/sec!!!!!! so it's a pretty totrture...
that's why i want to get all driver updates on media to attempt an upgrade in place before i give up and do aclean install. So bear with me and I appreciate your help; all of you.

You only need to put the wireless driver on a stick or CD, since the Win7 installer will have most drivers and their updates and other drivers will be delivered almost as soon as you connect to the internet via optional Windows Updates. So if you come out of install without wireless, install the wireless from stick/CD and connect to get optional Updates.

Any drivers then missing in Device Manager can be found on the Support Downloads webpage for your computer or device model.

All of this is in the steps to get a perfect OEM reinstall here: Reinstalling Windows 7
