I would agree with that

very unlikely to be the router.

seeing that win7 is the new component in the chain, I would say this is 
very likely to be the cause. Probably down to the win7 firewall or TCP 
stack limiting connections, in theory a packet sniffer would still see 
the packets getting to the win7 network interface but would drop the 
connection immediately.
