So I updated from SMB1 to SMB2 on my LS-WVL (LS-PRO-DUO) LinkStation using the instructions here:
http://forums.buffalotech.com/index.php?topic=24630.0And I can connect just fine from both Windows 7 and Windows 10 boxes. I can map a folder to a drive letter. I can connect via network name or via IP address.
However, my connection gets dropped from Windows boxes after 1-3 hours or so. When it disconnects, I get an error in Windows Explorer that says "Wrong parameter". Note that when this connection is broken, it is still possible for me to connect to the LinkStation by logging into the admin UI via the IP address in my browser. It is also possible to access files made available via the DLNA server. I just can't connect via the mapped network drive any longer.
If I log off then log back on then the connection is re-established.
Is this a problem with my SMB2 config on the LinkStation?
Or the network settings on my computers connecting to it?
It seems like it must be some kind of time-out, but I came across a dizzying array of different settings that might affect this, so I'm hoping to narrow down my troubleshooting with the help of someone who knows more about Samba or about the limitations of SMB upgrades on devices like these ones that don't officially support SMB2 even though it is available in the software provided. Here are some pages that I'm trying to search through for an answer:

Firmware: 1.74
2 x 2TB drives configured as RAID 1
For all mapped connections I use separate credentials with a username and password to access the drive that are saved as custom credentials when I set up the mapping, and that are stored in the LinkStation under users.
