I've just setup a new router for the office network, after a few problems it's up and running.
I have one problem left: there is an unknown device attached - if I turn all the machines off it is still there, its not causing any real problem other than it's using an ip address I would like to use.
The setup is all computer connect to a switch (Cisco catalyst 2950) as does the HP Business Injet and the router from which comes the internet.
Any ideas?
Also, some of the computer names are being shown - only unknown followed by the mac address.
I'm stumped.
Edit : The router is a BT Business Hub
