Time Capsule 2TB Slow read/write speed.

I have a Macbook Air June 2011 and a TC 2TB June 2011. I just bought a TC 2TB and I am very dissapointed in its transfer speed. Monitoring the speed on Activity Monitor and using a 5GB file and only 7 feet away from the TC. The top speeds are only 15 MB/s write and 21 MB/s read. Why are my speeds so slow, did I get a bad TC?

Time Capsule 802.11n (4th Gen), Mac OS X (10.7.3)

21MB/s assuming you are correctly using B for Bytes.. is fantastic.. how fast do you think wireless is??


Fastest in these tests ..

About 300mbits/sec that is around 30MB/s after taking account of wireless overheads.


You must have 450mbit to do that at 5ghz otherwise discount 30%
