sorry - I don't have experience specifically with Dlink routers, but
having used numerous different Linksys router configurations over the
years, I've had similar experiences of traffic freezing under certain
circumstances. Most often, the only solution was a firmware upgrade to
But there was one circumstance, where for the longest time I thought I
had to reboot the router. Finally I figured out, that in my specific
situation, I could just disconnect the uplink cable between the 2
misbehaving devices for a few seconds and then reconnect it, and then
things became ok again. It didn't solve the problem, but it gave me an
idea, that I was dealing with some sort of overloading problem.
I've mostly run switches for the last few years, rather than hubs - I
wonder, if the NFS traffic is just plainly overloading the router's
processing power, since all of the packets coming into your hubs are
showing up at the router, too.
I wouldn't be surprised, if some of the processors in the gear for home
networks are underpowered for a real traffic onslaught. Of course,
switches have the effect of thinning out traffic at each port, so they
tend to suffer less than hubs.
