Unable to connect to other connected devices

Jim_Elma, I guess some examples might be in order...

NEW VIEW (run from a CMD prompt):

===============

C:\>net view
Server Name            Remark
--------------------------------------------
\\IRV8700              Irv's 8700
\\LARAINE-XPS8500      Laraine's XPS8500
\\READYSHARE           readyshare
The command completed successfully.

=================

As you can see, although I also have an Amazon Echo and FireTV Stick, as well as 2 iPad's on the LAN, only the PC's (mine is wired, wife's is wireless) and the USB drive on the router have 'shares' on the SERVER NAME.

One can do a NET VIEW on any SERVER NAME and see the shares available, like:

========

C:\>net view \\laraine-xps8500
Shared resources at \\laraine-xps8500
Laraine's XPS8500
Share name  Type  Used as  Comment
---------------------------------------
C_disk      Disk
D_drive     Disk
E_drive     Disk
The command completed successfully.

==========

Since I know her IP Address I can also get to it that way (bypasses SMB1 by the way):

==========

C:\>net view \\192.168.1.40
Shared resources at \\192.168.1.40

Laraine's XPS8500
Share name  Type  Used as  Comment
---------------------------------------
C_disk      Disk
D_drive     Disk
E_drive     Disk
The command completed successfully.

=======

Now the USB drive on the router using the Server name and IP Address:

============

C:\>net view \\readyshare
Shared resources at \\readyshare
readyshare
Share name   Type  Used as  Comment
-----------------------------------------------------------------------
Movies       Disk           read:all-no password;write:all-no password
USB_Storage  Disk           read:admin;write:admin
The command completed successfully.

C:\>net view \\192.168.1.1
Shared resources at \\192.168.1.1
readyshare
Share name   Type  Used as  Comment
-----------------------------------------------------------------------
Movies       Disk           read:all-no password;write:all-no password
USB_Storage  Disk           read:admin;write:admin
The command completed successfully.

=============

 You can use the DIR command to see what is the Server's share, like :

================

C:\>dir \\readyshare\usb_storage
 Volume in drive \\readyshare\usb_storage is USB_Storage
 Volume Serial Number is 8A4E-F8FB

 Directory of \\readyshare\usb_storage

You can substitute IP Address for the Server name above too.

Now the NET USE command:

==============

C:\>net use t: \\readyshare\usb_storage
The command completed successfully.

C:\>dir t:
 Volume in drive T is USB_Storage
 Volume Serial Number is 8A4E-F8FB

C:\>net use t: /d
t: was deleted successfully.

============================

What I did was assign the share to my PC's T: drive. I can do whatever I wish with it now direct from my PC. The NET USE will show you what is used too. the command with the drive a /d will release the drive letter.

All you have to know is the SERVER name shown on NET VIEW, and the share names on the individual devices. On possible drawback (same as using the LAN method to access another PC) is you'll need ACCESS to the shares, which you probably already have.

Another thing, unless you've set up RESERVED IP ADDRESSES you can not rely on using the IP Address method as they can change depending on which device comes on-line first. In my case I did reserve specific IP addresses for ALL PC's.

Hope this helps. Reply back if you need more info or details.
