How do I resolve this Network folder issue

[Daff_Duck]

I set up sometime ago a shared folder so that everyone on could access it - I have a wireless router now for some reason even the folder is on my pc and shared on one can access it as the router seems to be asking for a password in order for the other computers to gain access.

I cannot and no one else in the family can figure out what it is asking for I have tried all variations without success.

So is there a way to bypass it or to overide it.?
