It may be corrupted registry settings too. If he uninstalls the adapter and drivers, then runs a registry cleaner to get rid of the old entries followed by a reboot and clean install that may do the trick.
I've had that happen as well.
Chev65: He could try using the MAC settings to change the MAC of his new adapter to that of his old one. IE: Clone it. I wonder???
I tried that... Didn't workand I didn't quite understand every thing ... what is mac anyway ? I tried physical address of my ethernet adapter (wich i looked in ipconfig "E0-CB-4E-0C-3B-89") then I changed first 2 values with "12" ... "12CB4E0C89" didn't work anyway...
wich values should i put in?
I suspect it might be the NIC problem ... How could I check if all my hardwer works properly ? In Device Maneger seems everything ok.
How could I run registry cleaner ? I can screenshot my registry or services ... if that would be helpfull to anyoneIt may be corrupted registry settings too.

How can I Clone mac ?
Could you look in to my previous post, where are screens of my ipconfig ? If I understand correctly... I shoud change from "E0-CB-4E-0C-3B-89" to "00-80-48-C2-39-3B" ?
ps: sorry for my bad english and thanks everyone for helping me... I'm hopeless
I solved the problem !(well You guys did)
i changed MAC from "E0-CB-4E-0C-3B-89" to "00-80-48-C2-39-3B" and it worked
I can't really belive it ... it was so easy... I'm so happy right now
ps: I'm not so hopeless afterall
I'm not sure what is up with these MAC addresses changing or becoming unusable but it seems to be another of those strange Win 7 things that I havn't yet figured out the answer too.
At least I thought of it in the first place I guess but that was because the other guy was having the same types of unassignable IP router problems so I figured it was just another strange MAC address problem.
At any rate I shall add this fix to my list of strange and unusual problems that only Windows 7 seems to have. I'm glad that you are up and running Lisjak. :)
I'm not so sure the numbers matching matter as much as just changing the MAC to something else. It seems like once the adaptor drivers were changed the router needed to see a different MAC address or it wouldn't assign the new IP for some reason. I would think a reset would fix that sorta problem though.
I'll bet the ISP has fixed the MAC address somewhere. The only logical place is via the cable modem.
I still think he needs to contact his ISP. The problem *isn't* his computer nor W7.
Glad you got it going!I solved the problem !
ps: I'm not so hopeless afterall
We're all here to help so don't hesitate to ask!
Yet another one solved for me, lucky guess. This MAC address thing is kinda strange.
My ISP do this too, they "locks" to anything that connects to the cable modem port (in my case, it's a Mikrotik router). If I were to change the Mikrotik router, I must call them and ask them to re-"register" my device before I can use the internet connection.
The Thread Starter's issue is definitely a Mac-address lock-in issue.
