creating a small network

[DjSwift]

I am trying to create a small network (so much for the MCSE and cisco qualifications..lol)

Its microsfot playing games with me and im not too sure what to do!!

I have 2 computers.

One computer lets call A connects to a wireless router which connects to the cable modem

Computer B is a desktop with wireless capabilities.

I just need some sort of file sharing system.

Its funny because my laptop when it conencts to wireless can be viewed by computer B

Also computer B can view and share files with my laptop. (vice versa)

Computer B will also see computer A but it cannot share :(

COmputer A only sees itself....lol

lol

ANy adivce?
