I was testing my transference between my Time capsule and my Macbook and I think that is a kind of slow, but I am not completely sure. I have calculate the wireless transference in 2.9 megabytes/second and the Ethernet transference in 12.7 megabytes/second. I think that they should be higher but I don't really know. My USB hardrive is going to 21 megabytes/second. Any idea of how to improve my speed? Thanks in advance. Best Regards.
