Take a look at these networking-related posts in the Hey Scripting Guy! blog. They describe how to use scripts to manage network infrastructure services, such as DNS and DHCP, manage network adapters, and even how to obtain the wireless connection signal strength (how many bars on your wireless strength indicator in the notification area).
If you are not doing scripting with PowerShell now, it is something you should look at as a key skill for the future.
