Not to mention environmental factors affecting any wireless
technology.  A faulty transformer on a nearby powerline "could" cause
interfeerence, though perhaps not in the GHz frequencies.  My
microwave oven obliterates the signal on my cordless phone (2.7GHz).
Also, wall warts (the brick power supplies) can cause problems too in
certain frequency ranges...

It's not always environmental like that, but there are things to consider.

HOWEVER, another test, I don't recall if the OP has tried this, but
transfer the file over wireless and figure out how long it took, then
hook the computer up to the router via ethernet cable and try it over
a wired network and see if there's an appreciable gain in transfer
speed.  If they are more or less the same (ball park numbers), it's
more likely a NFS or system level issue, as opposed to a
network/hardware level issue.
