80211n Wireless Pci Express Card Lan Adapter Exclusive !link! -

While 5 GHz is fast, it struggles with walls. 802.11n’s native 2.4 GHz band penetrates concrete and plaster far better. An exclusive high-end N card (especially with external, removable antennas) can outperform a cheap AC adapter in range. With MIMO 3x3 or 4x4 configurations (rare in low-end N cards), you get exceptional signal diversity.
