Command/Powershell script to reset a network adapter

You can use WMI from within PowerShell to accomplish this. Assuming there is a network adapter who’s device name has Wireless in it, the series of commands might look something like the following:

$adaptor = Get-WmiObject -Class Win32_NetworkAdapter | Where-Object {$_.Name -like "*Wireless*"}
$adaptor.Disable()
$adaptor.Enable()

Remember, if you’re running this with Window’s Vista, you may need to run the PowerShell as Administrator.
