I run XP SP2 Home (Media Center Edition). I connect to the internet via a Belkin wireless router/ADSL modem, with a Belkin USB wireless adapter plugged into my computer. There are no other computers in the network.
Since I set up this wireless network about a year ago I've never really bothered to look at the router's settings, on the principle of "if it ain't broke don't fix it". However in preparation for connecting my wife's new laptop to the network, I've been poking about in the router's settings today.
In the DHCP client list (which I don't think I've ever looked at before), I am surprised to find two entries. One of them has the MAC number of my USB adapter, but I don't recognise the other one's MAC number.
I'm not any kind of expert on networking - I just do what the instruction book tells me. Should I be worried about the two DHCP entries? Could someone else be infiltrating my wireless network? Or is it normal to have two DHCP client entries for one computer?
By the way, I have MAC filtering enabled in my router's settings, with only my adapter's MAC number allowed.
