Hi @maxthegamer4548 Had you tried pressing on other buttons? Had you test on another PC? If you press and use a little force, does it works? If it is under warranty, suggest you to send in for service. Else…. you need to open up and try replacing the micro switch first.

Hi @hppy2223 Suggest you to take pics to confirm. Generally some models of wifi card has 3 antenna, while some has 2. if the antenna is not in use, you can tape it to prevent shorting.
