mac address 00-00-00-00-00-00 on my network card - what does this mean?
Posted on 2004-04-24
I've been troubleshooting some problems with my cable modem connection. In the process, I discovered that my Windows XP Pro computer is reading my network card's MAC address as 00-00-00-00-00-00. This is invalid, right? What does this mean? My network connection seems to work fine, but I do have some intermittent connection issues and I'm wondering if this could be related. I tried changing the MAC address (I have the option to do so when I go into properties on the network card).
The card is listed as SiS 900-Based PCI Fast Ethernet Adapter. If I look at the properties and click the advanced tab, I have the option of setting a value for "NetworkAddress". If set to the "not present" option, I get 00-00-00-00-00-00. I tried changing it to 11-11-11-11-11-11 and that worked but I lost my internet connection. I think the change confused my router.
Anyway, I'm wondering what I should do...is the card bad...do I need to take it out and see if there is an address listed on it...should I just change it to some other value??? I'm open to suggestions - this is kind of a weird thing and I'm not sure what the implications are.
