AT&T is lying to you. There is even a web page where you can enter a new MAC (ethernet device hardware) address, manually. And, this is exactly where the problem is; I've been there*. You're connecting to a temporary address at ATTBI, whose connections only last for a few minutes. A new network card won't help you. Odds are 10 to 1 that neither your settings, nor your hardware, are to blame.
Some questions: Do you have a hardware or software router that provides NAT (network address translation) for the machines on your LAN? Was the B&W your 'official' machine with AT&T before you started the upgrades? While you were working on the B&W, where there other machines attached to your hub? Which cable modem are you using? Here is a process you can try: 1) Turn off the cable modem and unplug it from the wall. 2) Disconnect the hub from the cable modem. 3) Shut down the B&W. 4) Connect the CAT-5 (ethernet) cable from the B&W directly to the modem. 5) After at least 3 full minutes, plug the modem back in and wait for it to sync with the network. (All but one of the indicator lights will stop flashing. It won't be lit, at all.) 6) Once the modem is synchronized with the cable, start up the B&W. 7) Check the B&W's network status (in ASP, for example) and determine if it's using a real AT&T IP, such as 12.228.x.x. If that doesn't work, try steps 1-7 again, except do step 6 before step 5. And, if that doesn't work. Call ATTBI, again, swear you've never even heard of a home LAN, and tell them you've gotten a 'new' computer and need to set it up with the cable modem, instead of your earlier machine. Go through the motions with them. If they don't figure out that the MAC address needs resetting on their end, ask to go to "level 2" service. They can, btw, tell you what MAC address they have as being your primary machine. You can compare that number (the hardware address shown in ASP) with all your machines and see which one it is. The level 2 people can almost always figure this out and solve the problem for you. *(I use an old Pentium machine running OS/2 as a router/firewall. When this problem happen to me, I had also just installed a new TCP/IP stack from a CD. Unfortunately, the newer version caused a kernel trap every time it tried to renegotiate a new DHCP license. So, I had to research for a newer fix, shutdown, restart, research for another 5 minutes, shutdown, restart, research, and do on. Oy.)
