I have an older W510 (Lenovo) laptop that I would like to upgrade the Wifi card in. I believe it is a half PCI mini card...currently the Intel Centrino 6300 Ultimate. I opened up the laptop and immediately noticed the three antenna connections. In looking for a 7260 I found a half mini PCIe card but the picture shows it has two antenna connections. The colors of the three antenna connections in my laptop were white, grey, and black. Can I change out cards and just use two antenna leads? If so, does it matter what color?
