Live drive is very slow and poor support from WD

If you are copying such large data via wireless, that would be your bottleneck. Not MBL. I would think you are since your main and only reference was wireless N. Now, just because you have a wireless N does not mean all the wireless connections are Wireless N. It all depends on the hardware on laptops/PCs. Have a feeling some might be Wireless G.
