Get-NetAdapter
Disable the WiFi adapter using the interface description
Disable-NetAdapter -InterfaceDescription “Intel(R) Wi-Fi 6 AX201 160MHz”
“`
Using PowerShell Scripts to Disable WiFi Adapter
PowerShell scripts can be used to automate the process of disabling the WiFi adapter. Here’s an example of a script that disables the WiFi adapter:
“`powershell
Get a list of all network adapters
$adapters = Get-NetAdapter
Loop through the list of adapters and disable the WiFi adapter
foreach ($adapter in $adapters) {
if ($adapter.InterfaceDescription -like “Wi-Fi“) {
Disable-NetAdapter -Name $adapter.Name
}
}
“`
This script retrieves a list of all network adapters, loops through the list, and disables the WiFi adapter using the interface description.
Scheduling the Script to Run Automatically
You can schedule the script to run automatically using the Task Scheduler. Here’s how:
- Open the Task Scheduler.
- Create a new task.
- Give the task a name and description.
- Set the trigger to run the task at a specific time or event.
- Set the action to run the PowerShell script.
- Save the task.
Using Group Policy to Disable WiFi Adapter
Group Policy can be used to disable the WiFi adapter on multiple computers in a domain. Here’s how:
- Open the Group Policy Editor.
- Create a new Group Policy Object (GPO).
- Give the GPO a name and description.
- Navigate to the “Network” section.
- Enable the “Disable Wi-Fi” policy.
- Apply the GPO to the desired computers.
Using PowerShell to Apply Group Policy
You can use PowerShell to apply Group Policy to multiple computers. Here’s an example:
“`powershell
Import the Group Policy module
Import-Module GroupPolicy
Get a list of all computers in the domain
$computers = Get-ADComputer -Filter *
Loop through the list of computers and apply the GPO
foreach ($computer in $computers) {
Invoke-GPUpdate -Computer $computer.Name
}
“`
This script imports the Group Policy module, retrieves a list of all computers in the domain, and applies the GPO to each computer.
