aah ok just out of curiosity how can you tell what the devices are?

and i have no clue what the intel device would actually be (the wireless is pretty secured only thing i could think of that would be intel would maybe be my wireless card in my laptop since i think it lets me rebroadcast the signal from my laptop)

i do have a blackberry phone i connect to the modem at times.

and thanks david

Like a phone number has an area code and local exchange (ex; 212-555-XXXX) all MAC addresses have a manufacturer's address range in the first six hexadecimal digits.

40:6A:AB is assigned to Research In Motion (RIM).

Know the MAC address and you get a hint at the manufacturer. The RIM and Microsoft MAC addresses were easy. The first was assigned to RIM and thus must be a Blackberry. The second was assigned to Microsoft and you stated "...been trying to set up portforwarding for my xbox..." so I knew it was your XBox. Intel makes chip-sets and it could be Ethernet or WiFi for any device so that's a bit harder.
