wireless network card for a Toshiba Satellite 1405-S151 laptop

i recently reformatted my hard drive on my laptop but didnt think to backup the drivers, so basically, all of them were lost. i managed to restore all of them but the wireless network card/adapter. im not sure what cards were installed before, but im pretty sure it was a dell truemobile wireless card. i can still access the internet through an ethernet hookup. is there a way to download the network adapter/card? i havent been able to find one to install...or is there a way to find out what driver is needed when it isnt installed

If this is the proprietary wireless that came with the Toshiba Satellite, that is easy to find online.
If it is a wireless card you installed, and therefore have, you can look at the numbers on the card, then do a google search with those model numbers to discover there the drivers can be located.
Be sure your old drivers are removed from the Devices list in Hardware in Control Panel.
