Hello, i have a following question: I'm going to order Dell E6500 with WiFi 5100 and no WWAN card. 5100 uses two antennas. Later, I'm going to buy WiFi 5300 and Dell 5530 3g card. 5300 uses 3 antennas, 5530 - 2. Question: do all E6500's have all 5 required antenas installed all the time, or do they only get installed if you order cards requiring them? Question 2: if all 5 are present all the time, which ones connect to which? From what I saw, there are white, black, gray, gray-black and blue antennas present. White and Black are connected to 5100. Thanks for any help!
