Can't see my computers from either one to share files & print

Hello,

I have Laptop & PC both with XP HE & the MSBN Wireless-G
Kit MN-820 which came with wireless base station MN 700 &
wireless Notebook Adapter MN-720.

I have PC as base station & the Laptop withe WNA MN-720.
The problem is I can't see the PC from the Laptop nor the
Laptop from the PC. When I check my workgoup computers
from the laptop I can see only the laptop but not the
PC. When I try to view the workgroup computers from the
PC it gives me an error say noaccess.

The laptop gets the signal of the network and is able to
connect to the internet. However when I open the MSBN
utiliy it gets disconected from the network.

Please, please help. I have I have reset the network
wizard a gazillion times but still can the light at the
en of the tunnel.

Thanks,

Maria
