I've noticed that there is a unknown device that is connected to our home network so i have blocked it and it appears to be trying to connect every 2hours.

I'm really stumped on what this device is as it has used 5.50gb/250mb of traffic in the past 15 days.

Does anyone know how i should go about looking for it? I've asked around the house and it doesn't appear to be anyone's device.

MAC Address 88:12:4e:06:43:e2
Manufacturer Qualcomm
Source Device OUI

88:12:4e - seems that range is a Dell device.

Change your wireless password to something else? Preferably a longer password and make sure that WPA2 AES (not TKIP) is only enabled, not WPA.

Lots of devices use WiFi these days. If your router allows it, as soon as you connecr something make sure to change its name in the router's tables.

Scales, Freeview boxes, security cameras, smart plugs and so on. Think of all the stuff you have...

it can be well the same device you see, but over IPv6 and duplicating MAC address

MY DHCP server shows these separately and sometimes MAC address is missing from IPv6 enabled device.

Have you got Fing?

https://www.fing.com/

It can help by telling you what services and ports are running on the device (amongst others)

... But you have to let it back on to your network first .....

Yup I've set up my router to show sensible names for all the devices on my network. It also lets me assign a little icon to each device, which I find handy.

Chromcast in the back of the Lounge room TV? That kind of data volume suggests media streaming more than "smart" device telemetry.

Maybe someone in your house and the neighbours hit the WPS buttons at the same time as each other and it's their device.

Thanks mate, that helped me narrow it down to an old dell tablet that i was upgrading to windows 10 and left in the bottom of the drawer because it was taking forever to download. I feel so dumb now, i thought it was a neighbour or someone trying to steal our wifi lol

It's always the easiest solutions that are often the best. And it's unlikely that someone has gone to the effort to hack your WiFi.

Last week my daughter gave a friend of hers the WiFi password. So I asked around the house who "Grilled-cheezus" was... Embarrassed daughter, embarrassed friend... Yes your parents are keeping an eye on you lot.

I'd have attributed that name to you straight away!
