I'm running Win10 20H2 OS build 19042 on an HP Spectre laptop. I use a TP-Link AX6000 wifi router with an external hard drive attached via USB for use as networked file storage, backups, etc. For whatever reason I can no longer access that drive. In File Explorer, under Network when I click Network, I can now only see my own laptop listed in the left pane, while in the right pane I see my laptop, my networked printer, and the Sonos wifi speakers. I used to see my other laptop and the //tp-link share for the hard drive attached to my wifi router. My home network is set to Private and I have rebooted the wifi router, the external HDD, and of course my laptop. I tried to map a network drive to the //tp-link share, but of course that path could not be found.
What else can I check?
