help with home networking

[kelly91]

Please help. I'm trying to fix my home networking. I am trying to share
printer and files. This all worked until a little while ago. I'm not sure
what changed.
All computers connect to internet wirelessly. Have ATT U-verse internet.


I have desktop PC (window XP) that is connected by usb to printer, and two
notebook computers (one MAC and window XP).

on my desktop- when I go->start->my network places->local network->shared
kelly computer is listed. also in my network places->the internet-> several
computers are listed , including my mac.
the firewall is set to ->on->file and printer sharing is check as exception.

On my Mac, I can not "see" the other computers on the network, I can't print
or share files. the computer is set to share files and printing.

I can't firgure out what is wrong.

Hi
The best approach is to forget about "It was working, it stopped working, I
did not do anything and do not know why".
Relate to it as though you have a new system and you are going to manually
set it for File /Printer Sharing.
Make sure that the Software Firewall on each computer allows free local
traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should
be Off, and the active Firewall has to adjusted to your Network IP numbers
on what is some time called the Trusted Zone (consult your 3rd Party
Firewall instructions.
