Windows 10: unknown device on network

Hello,

I use WiFi Guard to monitor my network devices, and have a device showing up on the network that I cannot account for. The network belongs to my roommate, and in addition to my devices, I've identified all her devices on the network. But this one device shows up at 10.0.0.11 and I have no idea what it is.

Today I was home alone, talking on the phone with my computer open in front of me, when WiFi Guard popped up an alert (I've got it set to scan every 10 minutes until I get this figured out), after having been "quiet" all morning. Since my roommate wasn't home and I activated no devices before the alert, I can only assume we have an interloper.

Is there any way I can use the MAC address to track down this device? Or can someone suggest something else I can do to ID it?

Win 10 ver 1909

Network devices listed under Unknown in Device Manager


I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.

 

X800 GTO2 = Unknown Device

I flashed the BIOS on my X800 GTO2 last night and it is listed in the Device Manager as an Unknown Device. Is this normal?

Hi,



Thank you for writing to Microsoft Community Forums.



This issue could be caused if there was device connected to the computer previously or if there are currently any device connected to the system.



You can try the methods below and check if it fixes the issue.



Method 1: Check of WIFI security.



If you are using WIFI, hotspot or Bluetooth, I suggest you to check if all of this connection types are password protected, if your WIFI is open network then any phone or PC with WIFI can connect to your system.



Method 2: LAN check.



Check if there are any other systems connected to the same LAN network.



Method 3: Check connected devices.

1. Press Windows + R key on your keyboard together.
   
2. Type control printers and hit enter.
   
3. You will see all the devices and printer connected to the computer.
   
4. You can right click and remove any unknown devices connected to your computer.
