Okay, here's the background to all of this. I'm trying to create a wireless p2p network in my house so that I can share files and my printer from my desktop computer, which is hardwired to a router, and my laptop, which is wireless. I've tried everything I know, to no avail, and google and a search of this forum didn't turn up anything relevant to my situation.

The main computer, my desktop, is running Windows XP Home Edition Service Pack 3. The laptop is running Windows Vista Home Premium Service Pack 1. Right now I can connect to the internet fine on both of them. They both connect to a wireless G router, although the desktop is connected through an Ethernet cable.

As of now, both computers have unique names and are both part of the same workgroup. The router's DNS can resolve each host name from the IP address and vice versa but I can't ping either computer from the other. A tracert won't even make the first hop to the default gateway.

At this point I'm rather confused. I've only ever set up wired p2p networks before so this is a bit of a step into new territory. Anybody have any ideas? If you need more information ask and you shall receive.

Disable the firewalls for testing.

Well I'll be damned. That worked perfectly. Does this mean I'll have to keep my firewall disabled permanently or can I make some sort of exception rule for the connection?

Exactly !!!
That means, you have to figure out, what roles are needed.
Microsoft file and print sharing uses the ports
netbios-ns 137/tcp NETBIOS Name Service
netbios-ns 137/udp NETBIOS Name Service
netbios-dgm 138/tcp NETBIOS Datagram Service
netbios-dgm 138/udp NETBIOS Datagram Service
netbios-ssn 139/tcp NETBIOS Session Service
netbios-ssn 139/udp NETBIOS Session Service

Please send a reply, if you solved the problem !!!

Hmmm... Might be easier just to kill the firewalls, lol. The router acts as a hardware firewall anyway. I'll have to look into that in excruciating detail once I get the time.

The exception would be file & print sharing. It's listed under exceptions.

The advantage of running the software firewalls is they alert you to outgoing rouge traffic. The router does not do that.

Properly configure the firewalls is the correct solution.
