thisMAC addresses

Hi all

I have just done a reinstall of the Windows Vista home premium on my
computer I also reset the router, before I had the system setup and running
time in the speed touch 510 setup application which I got through the IP
address to the router and MAC address was displayed as a name now after the
reset it is just numbers and letters does anybody know why this happened I
have tried to change their numbers and letters back to the computer name but
this does not work.

Does this matter.?




When I use the IPconfig command from the command line the MAC address is
shown as numbers and letters.

Thanks for any helping you can give with me with this matter.
