Cannot get tversity to work on a wireless network

[ant3b]

Hi Guys,

Not sure where they should go but... here goes

My mate has a wireless network which i have set up. It consists of:

1 x belkin router (wireless)
1 x ps3 (wireless)
1 x pc (wireless)

The pc can ping the router and ping itself.. but cannot ping the ps3.. I have turned all firewalls off. Completey and enabled upnp. Still cannot ping the ps3? Is it because they are both wireless? I have checked both ip address's on the router and both are on the client list. Also there is another problem the pc cannot connect to the router through IE?? but can connect to the internet through it. Im a bit confused.. never seen this before at all. Would putting thr ps3 in the DMZ work? would turning NAT off work?

Anyhelp will be great.
