i've just upgraded to VM's 50Meg service with a netgear WNR2000 wireless router.

when i had my old belkin wireless router in,i could run java ps3 media server (PMS) fine.
i could stream all my movies from the machine upstairs to the tv downstairs via the ps3.

problem is now,
via the netgear wnr200 wireless router,i can't.
the machine upstairs won't see the ps3 and the ps3 won't see the machine upstairs.
BTW,yes i do a an "N" series dongle in the machine upstairs.

i've tried everything,port forwarding,turning off the routers firewall and so on.

i'm tempted to plug the belkin back in just to make sure it all still works as it did before.

any of you guys any ideas as to why i can't use PMS via the new router?

TIA.
