To communicate with a wireless network, a computer needs a wireless local area network card, also called a WLAN adapter. This adapter connects to a mini-PCI slot on the motherboard. Two antenna cables attach to the card, and these cables send and receive radio signals, allowing the computer to interface with Wi-Fi devices. If your computer fails to find or remain connected to local wireless networks because of poor signal strength, you can adjust the settings on the WLAN adapter to improve reception.
