Should I be worried about that? I could not really find a clear helpful explanation. My best guess is it is what came out before Wireless N was finalized. What are the differences exactly? #2 Is the extra price worth it for the D-Link? D-Link ($54.88) ASUS ($27.99) in my case. #3 Is there another PCI Express Wireless N adapter I should be looking at? It would be nice if there was a 5Ghz one but I can't find any. Network Setup: Linksys E3000 upstairs Another rig upstairs connected to E3000 with CAT6e Sig Rig downstairs almost directly below the router. Usage: Transferring / Streaming (1080p) large files. I need maximum throughput.
