windows not showing ReadyNAS name in network

Hello, I'm not sure if this reply is in the correct spot but after searching for a solution myself I read many of the comments here I also have had problems over the last few days since upgrading the Firmware to 6.4.1 on my NAS RN202 - I wasn't sure if was a Windows (10) update that caused it or something else but everything changed and my NAS202 stopped showing up under 'Network' - I was able to improve this by moving some files and folders into different directories as it seemed that the more files the unit had to refresh (or what ever the NAS does) the more often it couldn't find things, I also found that some of my permissions seemed different (always take a screenshot of what works) but the REAL kicker was when I discovered that under Accounts >> Authentication >> Workgroup Name: this had somehow become VOLUME... I would never have called it this opting for the more obvious choice of WORKGROUP... once I changed this everything started working correctly again including on my Laptop connect wirelessly to the network. Might be something to check :-)
