Whether you're installing a new Broadcom 802.11 mini-PCI wireless network adaptor for the first time or you're reinstalling it, you'll need to attach the antenna correctly to ensure you're getting the optimal reception. Broadcom 802.11 mini-PCI wireless network adaptors are installed in a slot on your laptop's motherboard and are accessible through a small panel on the bottom of the laptop. The antenna is made up of two wires (a main and an auxiliary) that connect to the mini-PCI card and are easy to miss when installing, but are integral to the wireless adaptor's performance.
