I have- New Asus laptop, w/ Gigabit card (SSD HD, Intel 3rd gen i7, 1600 Mhz bus) WD Mybook World D-Link DIR-855 w/ latest firmware update Cat 6 cable connecting computer, Mybook, and Asus laptop. No more than 15 FT of cable run. (all in same 8x10 rm) I'm only getting, according to Windows 8 transfer data, 12-14 mb/s. I know this is 100 mb/s tech and that I should be seeing 40-60 Mb/s if gigabit is working. I don't think the WD My Book World is the bottleneck. I swear I've seen GB speeds on different equipment to that same drive in the past, but I can't be 110% if that makes sense. Where do I start to troubleshoot? I'm not dumb, but I'm far from a knowledgeable network guy. Help help help is appreciated appreciated appreciated!!!
