Can't access NAS drives/shares on home wifi LAN

Please bear with me - this is a long post


Recently I installed a new Synology NAS drive on my WiFi home LAN, configured as RAID1; it is seen by the router, and is deemed healthy. However, I have had great difficulty making it visible on and useful to the PCs on the LAN. After much online investigation I finally got my Win10 Pro (ver 1909) PC to see the NAS in File Explorer; but I could not map the "shares" I created to the LAN or access them to read and write files through Explorer. I then found and applied these steps to "Ron", the first-named of several planned shares (mapping it as network drive R):

In Regedit, delete (if they exist) two Registry keys for mapped drive R:
HKEY_CURRENT_USER\Network\R
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Map Network Drive MRU\R
Close Regedit, remap share/drive R via Admin Command Prompt, as follows:
net use r: \\NASname\Ron /user:SynAcct SynPW /Persistent:Yes
where: NASname represents the name I assigned to the Synology NAS;
SynAcct represents the Synology account name I created;
SynPW represents the Synology account password I created.
Reopen Regedit and add this value:
HKEY_CURRENT VALUE_USER\Network\R the above net use command restored this key

"ProviderFlags" = DWord:00000001
This works: The drive Ron(NASname) (R:) is visible and fully read/write accessible in Explorer.

However, after rebooting Ron(NASname) (R:) is still visible in Explorer, but is NOT read/write accessible! The persistence failed. I also tried:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\.....\Map Network Drive MRU\R,
added the value R REG_SZ \\NASname\Ron

Again, after reboot, drive/share R is visible, but not read/write accessible. Every attempt to access it fails and raises the dreaded "Enter Network Credentials" dialog box; and nothing I enter therein works. I have yet to find anywhere a clear, concise definition of "network credentials" and how to determine exactly what they are or need to be for my PC/LAN system and NAS-access situation.

How do I resolve this matter? What Windows settings and/or Registry adjustments will make the mapped NAS shares always visible and fully accessible on this and the other Win10 PCs on the WiFi LAN? I hope someone can guide me through this process and/or point me to links that clearly explain how to do it, because I am really stumped.

In my travels through the Internet in search of a solution, quite a few other people also seem to have this or a similar problem mapping and accessing network drives. Several strongly suggest that Windows has a problem that Microsoft needs to fix.
