Random devices showing up on windows 'network'

Hi,

 

For a very long time I have had devices appearing and disappearing on any machine on my network.

 

Here are the two most recent ones in 'Network' on windows: http://prntscr.com/6wlxqd

 

Here is the properties window of 'e3_emea_3uks': http://prntscr.com/6wlebw

Here is the properties window of 'C1905': http://prntscr.com/6wly81

 

I do not own any devices with the same name as those. I also do not own any devices with that MAC address. 

 

Currently I have limited my devices to three on the network. These are trusted devices.

 

 

 

What I have tried:

  • I first noticed a few weeks ago and so I changed my router password. At the time, this had seemed to get rid of them, however I was not paying close attention and only noticed last night that they were back. 
  • I found that my virgin superhub (provided by ISP) had many security flaws in router mode. I bought a Netgear R6250 today. Same situation. (I used a new password to set it up & did not enable WPS)
  • I disconnected Ethernet from my desktop for 30 minutes. Whilst they still appeared on my laptop, they did not appear on my desktop. 

These mac addresses do not show up on 'Attached devices' on either the old router or new router.

 

**EDIT**

Other device names have shown up before, one being LG Electronics. I do not have the MAC address it displayed as it was not saved. 

 

These devices mentioned have never been on my network before. Only I know the network password, so anything would have to get by me.

 

There has never been an unknown computer show up either

 

 

Help would be appreciated :),

-James

Have you ever found out about anything that might be causing it? didn't look too far but it doesn't look like a common thing to be happening lol

those are probably hidden devices that were connected to the pc at one time..but aren't anymore

theres a setting you can change to turn it off

go to device manager and click show hidden devices

If you need remote help fixing something on your computer

I can help over Teamviewer if you wish

just msg me on my profile

These devices weren't ever connected to this PC (they aren't brands my family or I have gone for & this is a recent reinstall of windows). They don't show up in device manager and they're only occasionally displayed too, as if something loses connection rather than displaying history

Modem was provided by the ISP; Virgin Media Superhub 

 

Router is Netgear R6250 AC1600

 

I put in the netgear router today as I found VM SuperHub had many security flaws when running in router mode and it was recommended to keep it in modem mode only, which it now is.

I'm unsure and since I have no friendship with close neighbours, it'll be hard to find out.

 

**I disconnected my WiFi extender about 20 minutes ago to avoid further complication for this. So far, no unknown devices.

The WiFi extender wasn't powerline; it just acted as a bridge. However,as a temporary solution it has been replaced by a powerline adaptor. 

I'll probably try asking them  tomorrow.

 

It looks as though the WiFi extender had a big role in whatever was causing it so i'll leave that out for a few days to see if anything returns... Doing virus scan on every machine that had seen these devices, I need to go to sleep now (11pm). Thanks for your help so far :)
