I just got a refurb HP EliteDesk PC, and it set up perfectly well. Win 10 Pro, 64 bit. I have a home network with a WD Passport USB drive connected to the router, and it's visible and available to all the other computers, just not to mine. As far as I can tell everything is set up correctly.
Now, devices periodically drop off the network, most recently my husband's Canon 3-in-1 printer. It magically reappeared after he rebooted the router (Linksys06138). Other computers in the network appear and disappear on the new computer.
Any ideas for getting access to the shared drive? If you need more info, let me know and I'll try to get it for you.
