What are you using to download? Do you maybe have ports that need to be 
forwarded to your laptop when it's behind the router?

If this isn't a simple port issue, then perhaps there is an issue with 
one of your NICs on the router.  It's possible this old box is starting 
to ware out - it's got to be over 10 years old after all.  It's about 
the only thing I can think of if you were getting better performance 
from this same router before.  Unless something else has changed 
(different software or hardware?).  Changing it's position in a network 
shouldn't make a difference to the speed traffic passing through it.
