For what you get for that $84.4 is pretty amazing
50gb DL limit over 5 days
As far as i've been able to tell the upload space you get is
over 40gb (my current usage)
I wouldn't have thought it would be your router as the downloads are port 80
It's either at peak times your net gets capped off or they are throttling you
for dling to much.
As far as the storage limit on RS there is no limit, if you store more than a certain ammount it just gets changed to a high capacity account or something. Its the Download limits they make their money on so the more stuff that gets uploaded the more stuff can be downloaded.
