Looking to upgrade my current router/ap to the above model, my question is, what kind of transfer speeds (mb/sec) can I expect between an N spec device like my Samsung Galaxy S2 and my file server? eg sending a file in this direction:

FILE SERVER ON CAT5e-->GIGABIT SWITCH-->Netgear DGND3300 (using N)-->SAMSUNG S2 (using N) range less than 5m, no obstacles.

I'm not looking for a specific answer, just a ball park figure (mb/sec) if anyone has the above model of router and transfers large files to a N capable device.
