Extremely slow down loads from os5 my cloud

I recently set up a ex2 ultra system. I am wanting to down load some large files from a friends my cloud. When I select the file and start the down load it works fine for a short time10-12 Mbs then it starts dropping off until it gets down to 100-112 Kbs. What can be done to resolve this.
