Windows 10: Network drive not reconnecting yet files accessible via mapped drive

My backups to a NAS drive haven't worked for a couple of weeks after several year's of working successfully and it looks like a network problem. Here's the gist:I am able to view files contained on my NAS drive by using a Mapped drive in File Explorer - yet it doesn't appear as a valid device in the Network section of File Explorer.If I look at the device status in the Device Manager it sometimes says it's "working properly" and sometimes says "device not connected". I've no idea what causes it to change back and forth.Interestingly, I can still access files on the drive via File Explorer ev

Mapped Network Drive Disconnects and Will Not Reconnect

OS:Windows 10 V20H2
PC: Dell XPS8940
Router: Netgear R7000 w/ TomatoUSB

• Nine of ten mapped network drives on my desktop PC behave normally! The tenth is a problem. It is mapped to the USB drive connected to my router.
• Sometimes (days) I cannot connect to this mapped drive and it fails to reconnect. At that point I can still connect to this drive from ALL other devices on my Workgroup LAN. None of those devices have the drive mapped!
• For a short time, using "Net Use" shows the drive trying reconnect. Later it says "Disconnected".
• The only way I have found to reconnect to that drive is to perform:
  1. net use U: /delete
  2. net use U: \\HARENET-HD\data
• This problem has started within the last several months. Maybe it's related to a Windows update??

Help would be appreciated!

reconnecting file drive

Is this a File History Drive or a Mapped Network Drive? If its a File History drive, as recommended, just reconnect the USB drive and the backup will resume automatically.

 

Trouble Mapping Network Drive

I have a WD NAS drive connected to my router and have mapped it on three of my computers. I just setup another laptop with Windows 10 and have updated it to 1809 and when I tired Mapping a network drive nothing is displayed in the browse window except the
computer I am currently using. The drive is shown under network locations in File Explorer but not when you select map network drive and browse. I right clicked on the drive and selected properties and noted the IP address and went back into Map network drive
but instead of selecting browse I entered the IP address but it still does not map the drive. The strange part is if I go to any of the computers that already has the network drive mapped and select Map network drive and select browse none of those computers
show the drive either but you can select the mapped drive in the drive list in file explorer and it works just fine.

I have read several articles both here and elsewhere and tried the suggestions but nothing works. Network discovery is turned on as is file sharing and also checked if all three boxes under SMB file sharing support in Windows features were also checked and
they are. I have mapped several computers to several different drives over the years and anytime the drive was not listed it was always easy to go into Network Sharing Centre and find the problem but everything seems to be as it should so would appreciate
if someone can suggest something I may have overlooked.

Thank you
