Or you can try to do it in the NIC settings or the registry. The TechNet link below covers most of the ways you can do this. How to change a MAC address on Windows 7

Follow this steps:

Network and Sharing Center > Change adapter settings > right click on adapter name, then Properties > Configure > Advanced tab > Network address> put some values in and it seems like starting with 12 works best for Windows 7 according to TechNet site.

It worked for this guy anyway and it's all I can think of.
Unidentified Network - No Internet Access
I'm pretty sure this post had something to do with solving the problem. And yes I would call the MAC address change a last ditch effort to make it work again. I even looked up an alternate way to change the MAC at TechNet using the registry. This was a very recent problem over at TechNet.

What I think happend is that the MAC address was somehow cloned by the router so it would not assign a new IP because of that, I think your correct about that RedBird. Or the modem just wasn't up to par but I certainly never had those problems with my modem.

I've changed routers 4 times and never had to call my ISP.

I've never seen it on routers or DSL modems. Only cable modems which is what the OP had if memory serves me.

I blew 2 hours of fiddling at a friends house before I figured out what it was. Just about drove me nuts. I agree it's not something you'd see frequently.
