No, you don't understand.
I assigned the IP addresses to the two different MAC addresses (old and new) in the router. In my post I did not want to say "I
assigned this IP address to that MAC address" and specify both numbers because I did not want to share my MAC addresses with the
public, that is, readers of PCBUILD.
Imagine this happened in the router, using fake numbers to protect the innocent,
old MAC address, 00:1e:d9:b6:95:ae got paired to DHCP address, 192.168.0.105 and,
new MAC address, 00:19:f2:e0:7c:1f got paired to DHCP address, 192.168.0.106
Then, when the computer boots, the router assigns 192.168.0.106 to it, because it "sees" the new MAC address as the address of the
computer! In other words, the router thinks my network controller has a new physical address.
My ACTUAL "new MAC address" may be being shared by everyone who downloads those new bios, but they don't even know it - and won't
have problems because they are hidden behind a router.
I wanted to report this problem to ASUS, but they want all sorts of hoops jumped through before they will accept your email. They
expect you to go to their forum first, I guess. A quick glance at their forum didn't show anything like this. I may be the only
person in the world (now all of you) who knows about this bug, because I am the only person who was stupid enough to buy two of
their motherboards at the same time. :)

Those are IP Addresses and can be assigned and are determined by software.
MAC Addresses are unique and permanent and do not have dots in them. They
belong to the hardware.
Google MAC Address.

That is just the point.
Ever since my upgrades, the "physical address" - as given by the two
different computers when running "ipconfig /all" under a
command prompt - are the same. Somehow the bios seem to be taking what I
assume is burnt into the network controller's circuitry
and changing it to the same physical address. Either that or they are
actually changing the circuitry.
In either case, I have assigned in the router two different DHCP numbers to
two different MAC addresses. To the old MAC address is
assigned the number 192.168.0.150 and to the new "MAC address" is assigned
192.168.0.151. The number that gets assigned is the
latter! It seems to me that the router thinks that my new physical address
is the actual MAC address.
I am still wondering what is going on here. ? I thought that MAC addresses
were "supposed" to be unique and permanent.

MAC Addresses are unique to each Network Device.

I just discovered that I was wrong. Each of our computers now has new MAC
addresses, which are the same on all four network
controllers except that my two end with a 03 and 04 and her two end with a
03 and a 04, so we should be able to have unique MAC
addresses - at least as far as our lan is concerned. One of us will be an
03 and the other will be an 04. :)

Subject: [PCBUILD] MAC address corrupted?
My wife and I both have ASUS Striker II Formula motherboards - which I do
NOT recommend to anybody.
They have been buggy from the start, so when a new BIOS (drivers, too) came
out, I was eager to load the BIOS and drivers.
Now, however, I find that I have the same MAC address on my motherboard's
network controller (I only checked one) and on both my
wife's network controllers.
Does this make sense to anyone?
So, I loaded the old BIOS to my computer, but I still have the same MAC
address on the network controller!!!
Could this cause networking conflicts? Both computers seem to be assigned
different DHCP sets. However, my wife's computer has
downloaded multiple copies of emails.
Could this be malware related ( I mean malware other than ASUS's BIOS!! )?
Do you suppose that a simple network card will solve this problem for us? I
suppose that the actual MAC addresses are irrelevant,
since the unique DHCP addresses are what is important?
(I wonder if people all over the world that used these new BIOS are now
saddled with the same MAC address.)
Could the nForce drivers for the 780i chip be causing this, so that going to
the old drivers would help? (I will probably try
that.)
As you can see, I am a bit stymied by all this.
