 +==== 4. Temporary Method: Using iw (for Testing) ==== 
 +This is the quickest way to change the country code. It's perfect for testing if a specific setting resolves your issue, **but the change will be lost after you reboot the device.** 
 + 
 +=== Set the Country Code ===  
 +Open a terminal and run the iw reg set command with the two-letter ISO country code. For example, to set the country to Italy (IT): 
 +``` 
 +sudo iw reg set IT 
 +``` 
 +Verify the Change 
 +You can immediately check if the setting was applied using the iw reg get command: 
 + 
 +``` 
 +sudo iw list | grep MHz 
 +``` 
 +The output should show the frequency those are allowed in the set country. 
 + 
 +If this temporary setting fixes your Wi-Fi problem, you should proceed to the permanent method below.
