This is explained in detail in Clean Reinstall - Factory OEM Windows 7. Perhaps you should read it now that you've been reminded three times. Why would you come here for help and then just ignore it?
It says quite clearly you should put your wireless driver in your backup so if Win7 starts unable to connect to your network, you can install the driver to get online, enable Automatically deliver drivers via Windows Update (Step 3) and then run all rounds of Important and Optional Windows Updates, with reboots, until no more are offered.
This should deliver most drivers but any still missing in Device Manager can also be downloaded from the Support Downloads webpage for your exact model PC.
