Mystery Devices on My Network

[yz1234]

I logged on to my FiOS Router and saw under My Network(Auto-Scan Enabled), in addition to my 2 Dell computers that connected, there are 3 mystery devices, I do not know where they came from:

1. Name: ACER-5597DEBF0

    Type: Computer

    Connection: Wireless

    Status: Offline

2. Name: acer-55972debf0

    Type: Unknown

    Connection: Ethernet

    Status: Offline

3. Name: IP-STB1

    Type: Set Top Box

    Connection: MoCA

    Status: Online

I am 100% sure I only have 2 Dell computers connected to the Network since the day 1 of the FiOS install, can I safely delete the other 3 unknown devices from my router?

1 and 2 are the same thing, it has been connected both wired and wireless, that means someone connected directly to your router, most likely someone you know has a acer laptop that came over to your house and plugged in.

3 Is your TV Set top box, do not delete that device.

3. Okay got that.

But on 1 & 2:

No one ever come to my house with any laptop(any brand) and connected to my router, and I am 100% sure about that.

I am the only one knowing the WPA2 PSK, so I am very sure, I did not give it to anyone to allow them connect wirelessly.

then you can just delete it. If it comes back up then, I would worry about it.

Is it possilbe that my router was connected to the Acer while it's still in facotry?

Or my router was not a brand new one, Verizon gave someone else's router to me as a new one?

Just guessing...

[TimSykes]

Its always possible that you got a refurbished router.

Not cool if you ask me,

thank you TimSykes for the info.

um, yes, 1 & 2 are the same;  wireless and ethernet (2 different NIC's).  how does that indicate that someone came over and did anything ?

[cjacobs001]

oh, and if the router has been reset (effectively), there wouldn't be any way for anything from a previous location to appear in the 'my network' list.

Also, the original poster mentions '3 unknowns' , but there are only 3 listed, so are these the 3 unknowns or are these the knowns?

I can give a better answer.  The mystery devices are the fios techs laptop.  They wire in to do the original setup, then wirelessly to test the signal.
