Sharring files/folders on my XP home network

On my XP network, i am sharring folders from my Dell desktop and wireles laptop tyo one another. Ive ben to Microsoft and followed the instuctions on file sharring. But, I still can not see the other computer's share folders and thus share bertween my two computers. Is there somerthing else I need to setup to alow file sharring? Is there something I must set in my wireless router?

Any thoughts?

thx
