Can`t see my network on finder :S!

[Grfelix]

hey guys, Im a new mac user, but I have a problem with my network since yesterday, Im using a Macbook (Santa Rosa C2D 2.2 with Leopard) I always have airport activated because Im using wireless internet, but since yesterday I cant see my other PC on the network, and I need to constantly enter to my PC to share files between, but my PC just doesnt show on the finder.... anyone knows how to solve that problem??? is there a problem with the network settings of my macbook or with my router???

Thanks.

It depends on how your network is connected, actually. If your network looks like the following you'll be okay - this is how my network is set up.

(Internet)
|
Modem
|
1-Port Router
|
Hub
|
Devices

If, on the other hand, you have something like this:

(Internet)
|
Modem
|
Multi-Port Router & Wireless Access Point
|
Devices

You will have problems if the router doesn't support file sharing pass-through on the Local side.
