Windows 10: Explorer can't find any network device

Hi to everyone,

I've just performed a fresh install of Windows 10 1909, after some hardware changes, and now my pc can't find any device in my network; sometime it can discover my router, but after some seconds it disappears. I've followed some suggestion under some similar question but none of them worked for me.

The network card that I have is a Realtek RTL8111H.

Thanks in advice for any help.

Explorer missing a network device


Hi,
Missing network device - EXTERNALDRIVE
Since the last Windows 10 update which I installed on Dec. 9 I am missing one devices in Explorer > Network on one of three network computers.
They are all present on the other two computers. One of these is Windows 10., the other is Vista Premium.
The complete device list under network is Frankspc, Charlottespc, and Sue_ASUS and ExternalDrive.
The missing device on the Explorer list on Frankspc is EXTERNALDRIVE. I can ping it at 192.168.1.3
Any Ideas on how to get it back in the Explorer list?
Thanks

Network Devices Not Showing in File Explorer

Windows 10. Have Desktop 1, Laptop 1, Desktop 2 and D-Link Network Storage in Home Network. Router/Modem is AT&T/DirecTV for telephone, TV and Internet. Internet works fine. Do not think any problem with Router/Modem. Network devices do not show in File
Explorer, consistently, notwithstanding that they are online and can be accessed, albeit in a sort of a workaround. I have had this problem for some time. Desktop 1 is primary computer. Network storage is always powered on. Laptop 1 and Desktop 2 are sometimes
on, sometimes off. When Desktop 1 is powered on, hit or miss as to what other network devices, even though powered on, are listed in "Network" in File Explorer. Sometimes Laptop 1 will be listed on Desktop 1 File Explorer. But no others. Not even Desktop 1
is itself listed in Network. At same time, I will then move to Laptop 1, and look at Network in File Explorer on it. Desktop 1 is not listed. Nor is Laptop 1 itself listed. As a workaround, at a time when a device, or more than 1 device, listed, I placed a
shortcut to the device on my desktop. Thus, if device not listed in Network, I click the shortcut and I can access that device to, e.g., copy a file. So, the device is on line. This is true for all the devices. However, when another program needs to access
a device on the network, such as using Acronis Backup/Restore from Desktop 1 to access the Network Storage, it cannot do so because the NAS "cannot be found." This is true even though I know it is actually on-line by use of the shortcut in accessing it directly.
Sometimes, purely by happenstance, I boot one or the other of the computers, and some, or all, of the network devices will show in File Explorer > Network; more often, none, or only 1, will show. I have tried unplugging / replugging power, on all devices.
I have booted only one, then another one, then another one, all in various order. I have "studied" Control Panel > Network till I'm blue in the face and can't seem to find any solution to this anomaly. Nothing seems to work. Any ideas out there?

 

What is this network device?


I woke my desktop PC from sleep this morning, clicked on Network and immediately spotted a Phone in the device list that doesn't belong to anyone here (a Blu brand phone which is unusual enough that I would know about it).

I clicked on the device and was able to view the MAC address, but nothing else useful. A couple minutes later it disappeared from the network list.

Then a few minutes later I went and looked at another PC on the same home network and saw the same phone in its Network list. It also disappeared a couple minutes after I clicked open 'Network'.

Scanned both PCs with various anti-malware programs including Malwarebytes - they look clean.

Any suggestions on what I was seeing, and if it's malicious how to deal with it?


UPDATE: It popped back up again. I checked my router's connection list and don't see it there. For now I blocked the MAC address in my router but would still like to know where this is coming from.
