I have my XP pc wired to my netgear WGR614 router. and a wireless G4 laptop. i am able to send files from my mac -> pc via aol instant messenger. but i CANNOT go vice versa. both computers ARE NOT using firewalls. i've talked to the netgear people and we've confirmed that both computers have successfully pinged each other. can anyone help me with this? i'm going up the wall b/c of this. thank you.
