Need help reseting my MAC address...

[Mpbojangles]

Earlier, I was told to make my LAN card work I need the (stupid) cable company to reset the MAC address.

Do I have to give them the IP to the LAN card? If so, how do I do this?

Plz explain how this works. Thanks.

Try unplugging the cable modem for a couple hours and repower it - that might work. If not, just call them and tell them you changed out your lan card and cant get on the net, let them ask you what they need to know.

Your MAC address is a 48 bit alpha numeric serial number that only your nick has, each nic has its own MAC address. This is what the cable or dsl companies use to verify yours is the actual machine that is using your account.
I returned 2 nics before I learned about this.
So do what glc said, call your cable company and tell them you replaced your nic and they'll refresh on there side to recognise the MAC address of your new nic.

Hmm My cable company, Comcast only needs my Mac Address off my modem and the serial number along with the model. They don't care what NIC mac I have in my PC. I do have to power cycle the modem and PC to get an IP address on my PC if I change NICs.

Once My cable company lost my Mac and I called them up, about 3 hours later they had it fixed on their side.

I changed modems once and they got the new info from my new modem and took about an hour and got me back on line

Does your cable modem show SYNC or the cable light on? When my mac was unregistered My modem lost sync. Cable modems are not like DSL modems. DSL modems connect via user name and password. Cable modems are on Mac address. They won't show sync if the mac is not registered at the cable company; DSL modems will show sync even when not connected if sync is on the line. (some DSL connections are called bridged and they work like a cable modem as in connecting via mac address but they will show sync if sync is on the line.)

and I know I just probably really confused the issued.

if they need the Mac from your NIC
in win 9X and ME goto start, run winipcfg
select your NIC in the drop down menu and you can read your Mac address in more info
xx-xx-xx-xx-xx-xx

in win XP and win2k
start run cmd
from command prompt
ipconfig /all
and you can see your NIC's Mac address
xx-xx-xx-xx-xx-xx

With my cable company, all you have to do is unplug the modem for 5 minutes, and plug it back in. Then it will work. That is what I've had all my friends do when they got routers and it's worked fine.

AT&T/Comcast goes by both the mac of the modem and of the nic, thats why you have to clone the nic mac into the router when you install it.

Hmm...Okay. Last question. I'll try the ez way first then give them a call. When you say unplug the modem do you just mean the CAT5? What I did last night was take the cat out of the usb slot and stick it in the motherboard lan slot. It didnt work after I went to a movie (the recruit was pretty cool by the way). Should I just keep it all unplugged for a while or what?

pull the power plug and let the residual charge in the flash memory discharge and that will "lose" your MAC address
