Ok had to turn on upnp even if i didn't want to for security reasons, but that seems to make my dchp list more stable. As for smb had to turn on and off samba shares repeatedly until it took switch-check-switch-check. Now my dchp list seems stable,no disconnects for the moment, and smb shows up on my computer. pretty buggy software. I believe that did the trick. let you know if it holds long term. good for now.
Thank you.
