Unable to see/access Share

[spindoc]

I have a LS-GLC65 LInkstation, its been hooked up to my network for years. Always worked fine. Then after changing out my modem and router, I can't access the shared folder.
My nas software sees the unit, I can do the I'm here tone, and I have mapped the drive, the drive shows up on my network places.

But when I try to access the shared folder, it says it doesn't exist.

....sometimes.... lol

It a crap shoot. One day it works, the next day it doesn't.

One day I'll be working and accessing files, then get up, come back 5 minutes later, can't access the folder.

If I browse the drive, I get the SHARE folder, but If i close the windows and open it back up, its not there, then I can't see if for a few hours.

Then after a couple of hours, it shows back up again.

What the heck do I do here?

Back it up immediately if you haven't lately.

This could be pre-failure behavior. That drive won't last forever.
