If your laptop is unable to connect to the Internet, can't find Bluetooth devices, or has poor Wi-Fi Connection no matter what network you use, your Wi-Fi Card may be the issue. Follow this guide in order to learn how to properly and safely replace your laptops Wi-Fi Card.

Wi-Fi Card's tend to go bad due to general damage and overheating, with prolonged heat either from poor cooling or prolonged use in hot environments potentially causing the Wi-Fi Card to randomly fail, or stop working all together. However most Wi-Fi Cards do not degrade due to age, and will only begin failing due to damage.

Before using this guide, ensure that the issue is with the Wi-Fi card. While replacing the Wi-Fi card is inexpensive, it is worth checking before if the issue is the Wi-Fi Drivers on the laptop being outdated or corrupted. Additionally it is worth trying the methods found within Wi-Fi Not Working Correctly, to properly diagnose the issue.

This guide requires opening the laptop case and exposing internal components. Be cautious of sharp edges and avoid touching any circuitry and exposed electronics to prevent damage from static electricity. Use an anti-static wrist strap (such as one of these) if possible, and make sure your laptop is completely powered off and unplugged before beginning the replacement process.

Slide a thin, ESD-safe pry tool or angled tweezers under the metal neck of the connector (as close to the head as possible) and lift straight up from the board.
When working with these connectors, it's key to always lift the head straight up. If pried on at an odd angle, you risk breaking the socket off of the board underneath.
Reconnecting these can be tricky. Use tweezers to hold the connector in place over its socket and gently press down with your finger or a spudger—the connector should "snap" into place. If you're having trouble, reposition the head and try again.
When putting the cables back onto the Wi-Fi Card, make sure that the cables are attached to the correct places on the Card.
