unknown phone appears as a conected devices in my network map.

I have been concerned about my systems security since upgrading to window 8 last November on occations a phone has appeared in my network devices list well windows knows the phone it can get make model and mac code but after clicking on the phones propities it disappears. At first I thought it might have got in through my wireless router which is a virgin super hub made by netgear and after a little digging I changed the password and even the way devices connect wirelessly and made my hug a mac code only connection. This worked for a few weeks then hey presto another phone or tablet appeared on my network. I even paid a extra few quid to Mcafee and upgraded to access all areas to cover my tablet and my our phone the issue persisted . I was so annoyed at this time but I had noticed the my processor was a 64 bit capable processor so I took the plunge and brought another windows pro 8 pack as the system had to have a clean install. All has been fine for six weeks since I upgraded to a 64 bit machine and suddenly it has all started again I have had three different devices appearing in my network map and I have not got a clue if my system has been compromised. Or is it this think is a way for others to connect to the internet for free using my isp which is illegal.

 

Does anyone have any ideas where I turn to, to solve this problem ?

I had the same thing pop up on my windows 10 machine.  M201 as telephony.  I am narrowing it down to the fact that my Router has a build in system for a 4G SiM card, which is my back up internet if my line connection should fail.  I think that's where the M201 device sits.  I guess I am wondering if you have a Mobile SIM card in your router as a fail over connection as well.

I had this issue ,i have searched a lot in the internet and no absolute solution for this, I have tried very simple way through the router by blocking the mac address of these devices and it works fine for me , you have to keep watching your network for few days and when you found any unknown device (most likely it is a phone with just MAC address and no IP address) block the the these MAC address in your router

hope it work with you
