wireless network problem. Help neeed.

[royboy151]

Hi all, I have 2 computers connected via a wireless nework.I can access computer A files from computer B but not the other way round. Computer A can contact computer B but cannot access the files. All files are shared. I keep getting an access is denied warning when I try to open coputer B files. The message I get is- You May not have permission to use this network. Belking (router supplier) and netgear (USB Card Supplier) both confirm the hardware is all running correctly.
Can anyone give me an easy to follow solution to this problem, Please.

Make sure that computer B has file sharing enabled.
