After discovering how easily WEP can be cracked and creating a long, secure WPA2 key, you've probably noticed it's a pain to setup the wireless when your friends stop by. Windows 7 makes this process easy.
Over at the How-To Geek site (my home away from Lifehacker), guest blogger Ciprian writes up the quick and easy process of transferring your wireless network settings from your Windows 7 PC to any other machine running XP, Vista or Windows 7. To transfer the settings for yourself, head into the Network and Sharing centre, click on Manage Wireless Networks, and then in the properties for your wireless network you'll find the link to open the wizard that will copy all your settings onto a flash drive.
Once you've got the settings backed up, you can use the bundled setupSNK.exe file on the flash drive to restore the settings onto another computer. Sure, you can always save the key to a text file, but having this feature built into the OS is very useful, especially since you don't have to mess around with wireless settings.
