Windows 7: Remove Unknown User From Network

Within the router's web based interface, try clicking on each item in the left pane (and if need be, making selections in the right pane) to see if you can find a list of devices that are connected to the router. It might have wording like DHCP table.

If you find something like that, then hopefully it will list device name, IP address and MAC address. You don't need to post the MAC address, just look it up using the link that I posted. Doing that might let you know the manufacturer of the device... or at least the manufacturer of the network interface adapter.

If we cannot locate this device name TOM, then you might want to use the router's MAC filtering (shown in your screenshot) to allow only your known devices.

Virtual machine wiki - https://en.wikipedia.org/wiki/Virtual_machine, you would know it if you had it, so don't worry about that one.

Having WPA2 security does not necessarily mean it is protected. Do you know if you have to enter a password while connecting to your wireless? Try forgetting the wireless connection with your phone and re-connect, see if it asks a password.

UsernameIssues' recommendation about the DHCP client table can work, some routers are just bad and fail to list every device (don't know why). Also check the DHCP scope (IP range) to see if it is static or dynamic.

Alternative and easier You should be able to get MAC of TOM by, first ping tom, and make sure of IP address, then also in cmd:
Code:
arp -a | find "xxx.xxx.xxx.xxx"
replace xxx.xxx.xxx.xxx with the IP address of TOM

In my network (W7Pro64 is a virtual machine)
Code:
C:\Users\Gokhan>ping w7pro64

If they are running WPA2, then a password is mandatory.

Try the instruction in screenpost, rogue name change to Tom

I've gotten the MAC address, thanks to GokAy, but tying that address to a vendor using the link you provided is impossible. Not only did the page take FOREVER to load (easily 5 minutes), but once it did load I could only view the first page. Trying to page beyond that always gives me 1eee.org is not responding with a suggestion to recover the webpage.

Your router should have an access control list for the wireless. Enter TOM's MAC address there and deny access. Then check your wireless devices for connectivity in case Restart the router afterwards as well.

That website does test one's browser :-)
Please post the first 6 characters of the MAC address for TOM.
