Slow transfer speeds / Streaming problems

I’m getting about 11 MB/second upload rates from my PC to the wdmycloud. Seems a little slow to me. 

Also am having problems with streaming movies on my boxee box from the nas. The movie often pauses (almost buffers) making it annoying to watch.

My router is an Asus WL-520GU and is about 40 ft (and downstairs) from the boxee box. 

Wondering if anyone can offer some suggestions on how I can get this running better?

11MB? Sounds lime you’re only connected using 100m Ethernet, not Gig.
