MSI K7N420 invalid MAC address?!

I've noticed this before that my MAC address on this K7N420 NIC is weird:
Description: NVIDIA nForce MCP Networking Controller
Physical Address: 80-80-80-80-80-03
the problem now is that I have a router here and I could set fixed DHCP tables but the router refuses to add that kind of address there, just says invalid.
is there something that I could use to change is permanently or use just a trick w2k that it's different... I know in Linux you can change the MAC.
btw is there supposed to be a sticker on the mobo somewhere that tells the MAC address? I didn't see any on the frontside.

did you flash it with bios 2.5 by chance
yes I tried that one too when it came out, currently using 2.7 bios....
hmm that macfix site is down that beaver posted there on the other thread...

Invalid MAC Address message ?

I'm trying to configure my Verizon firewall, which is MAC address authenticating, to allow a new machine. It's an older Windows Vista machine, and I obtain the MAC via IPCONFIG /ALL. I take the MAC's I see there and try to enter them into the Firewall config section of the router config, and it says "Invalid MAC Address" ? What's going on here?!
BTW, I already have about 8 machines configured and working just fine.
Solved!
Go to Solution.

While I see you solved your issue, there is a (or are) problem(s) to be aware of.
#1 MAC Address(es) are always sent in clear regarless if the type of encryption.
#2 Since it is possible to spoof/clone a MAC Address on a router (for example as shown at http://ui.linksys.com/files/E4200/2.0.25/wanmac.html ) it is also possible to spoof/clone the MAC Address on a computer.
#3 If someone does not know how to spoof/clone the MAC Address on their computer if you do not use wireless encryption (WEP, WPA, WPA2) to protect your wireless network, that someone can still see your traffic.

Invalid MAC Address Format Error

I have a WRT54GR with a 54USB Wireless Adaptor...and I am trying to put my PC MAC Address in the Allow Table so that this is the only MAC Address that can access my network...it is recognising my 54USB Adaptor MAC Address in the Table, so I select this, and add it to the table to allow access, and it comes up with Invalid MAC Address Format....
Anybody know why this is happening...I have tried adding it automatically and typing it in manually still the same. I use ':' between the numbers/characters not '-'.
Any help greatly appreciated....
Thanks
Smartie27.

Try it in the form xxxxxxxxxxxx and see if that works, or maybe just xx xx xx xx xx xx

Invalid Mac-address.

Dear NetPro,
Does anyone can guide me what to do now ?
your reply will be highly appreciated.

Regards,

Hi Jack,
How many of these packets are you getting ? If it's a small number, I would not worry about it too much.
However, if the number is significant you might not need to isolate it to the application on the server. In general, the IP to MAC conversion is done by the ethernet stack. But it may be an issue with the NIC or a mis-behaving application. It is not always easy to find out which application is causing it. You could do a couple of things (but none of those may solve the problem):
- replace the NIC
- shut down one app on the server at a time and see if the packets stop
Hope that helps - pls rate the post if it does.

Invalid MAC Address for ADMTEK in MS-6378

I had network connection problem with my MS-8378. After investigation, I found that the MAC address of the on-board ADMTEK NIC was corrupted and changed to 'FF FF FF FF FF FF'. Except this, everything is fine and the Windows XP can recognise the NIC.
How can I recover the MAC address?

I searched the Internet and found a number of similar reported problems. The following link contain a more detail description of how the MAC address can be corrupted by the driver of FreeBSD. It mentioned that the MAC address can be reset by the manufacturer's utility before it will work again in Windows. I have contacted the MSI support and still waiting for their response.

MSI 770-C45 - MAC address 00:00:00:00:00:00

I've just upgraded my system around an MSI 770-C45 motherboard.
I've noticed that the MAC address of the onboard RTL8111/8168B is 00:00:00:00:00:00.
Is there a way/utility to reset the MAC address in the ROM ?
The BIOS has been updated to V1.30, but this did not resolve the problem.
Thanks.

other than re-installing the net card driver you could try this utility to change the mac address to any one you like:

DHCP reservation BAD_Address and Mac Address changes.

Ok. I understand about Bad_Address and the things that can cause it. That said, I am using Window 2003 and we are running DHCP. Yesterday we had a series of short power outages. Some were right after the other (1 or 2 seconds) others
were 10 to 40 seconds in between. The server (of course) has a UPS and so does most of our infrastructure (switches etc).
But it seems that one type of Printer that we have, were all switched to bad_address and they could not pick up their reserved IP address. Some of them seemed to remember their IP and are still functional, even though their reservation says bad_address.
I assume they will fail either at lease renewal or the next time they are power cycled. What surprised me was that these bad_address entries' reservations were changed to have an invalid MAC address.
All of them start with a 0 or a 1 and are only 8 characters long. 0401150a, 1701150a, 1901150a, hmmm. i see a pattern forming. They all have unique first 3 characters, but everything after that is 1150a. That led me to figuring
out what this number is. It's an inverted hexadecimal representation of the ip address that is being complained about. Why would the DHCP server replace the MAC with this convoluted string? Is this covered in any manual?
I am pretty sure it's not in the DHCP RFC.
Not sure why it was having the problem, unless somehow the printers were powering and made the DHCP request then discovered that the old lease information was kept somehow (remember, some of the outages were very brief) after the request had gone out.
But that, and nothing else I can think of makes sense. And it only happens on one model of our printer. At least so far. And this isn't the first time we've seen it happen this way.
Any ideas appreciated.
Chris

Hi Chris,
Firstly, it seems that the Unique ID of the DHCP Reservations are inverted to the IP addresses in hex. And, the most possible cause is IP conflict.
For example:
0401150a -> 04 01 15 0a (hex) -> 4 1 15 10 (decimal) -> 10.15.1.4 (IP address)
Meanwhile, I agree with the possible cause as you said, however, would you please kindly let us know the following:
1. How many DHCP Servers do you have? Or, is the DHCP Server multihomed?
2. Do the printers have multiple NICs?
3. Are the printers both statically configured and have DHCP Reservations in the DHCP Server?
4. DO other DHCP clients in the same scope have the same issue?
5. Is there any trace in DHCP log?
In addition, if Conflict detection is enabled in your DHCP Server, please disable it and see how it works.
Also, please check if you can get some clues from this TechNet Thread:
DHCP server bad address issue
In addition, as the issue only occur with the same model of printers, it is worth to contact the vendor for their insight on it.
Hope this helps.

My router doesn't accept my MAC address

Hi.
I'm trying to set static IPs on my router (Netgear DGN 2000). I go to the "Connected devices" panel, and among them I can see my iMac. Its MAC address is odd ( like c4:2c:xx:xx:xx:xx). As I try to set a static IP, I get an error saying "Invalid MAC address". My other non-Apple devices all have MAC addresses starting with 00:xx:xx:xx:xx:xx and I can assign a static IP to them. Ihave the same problem with my MacBook.
Is there something wrong with the iMac? Or the router? Or both ?

I'm glad to hear that, Thanks
But I checked and there is no update for my router... Maybe I'll write to Netgear support, I would rather not buy a new router just to fix this problem!

"Your Machine MAC Address is Invalid"?

Hi,
I need to use a software that is based on Adobe Air but got trouble with my MAC address. So, every time I try to login to the software, it's always failed and "your machine MAC address is invalid".
There's a question that kept popping up after the installation and it hasn't appeared anymore after I click "Always Allow". Any idea what should I do to get this fixed? Because all other MAC users can use this software well.
Thanks!

- The MAC address you wrote is of the right format. Since it is unique to each device I can't tell if it is the one for your iPod. Are you sure that the password you entered is correct? Unless you turned it off, the first letter you entered is automatically capitalized. Carefully check each letter as you enter it. Also, some users have turned of Auto-Fill in Settings>Safari to get the password to work.
- Have you powered off and then back on your router
- Have you reset network settings:
Settings>General>Reset Network Settings
- Reset your iPod
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.

Entering the iPod's MAC address only helps if the router is set up to filter connections via the Mac address.

PC22224 switch fails on boot with message "Invalid switch MAC address"

Ok moderators, I know this is a nonsupported product, but you moved all Switch messages to the archive. This seemed to be the most appropriate folder for it. Hope that's ok?
I have a NEW (can you believe it?) PC22224 managed Cisco/Linksys switch with a problem. When it boots, it passes all tests until it is almost ready to run, then I get this message:
Checking file integrity..... Done
Decompressing Code Image.... Done
System PANIC.....
Invalid switch MAC address
Does anyone know how to correct this problem? I can find nothing on it anywhere on the web.
Thanks in advance!

Wi-fi MAC address is invalid

Hi, i have a netgear router and i tried to access the wi-fi. It said that the password was incorrect, yet it was. I tried registering the MAC address into the router, but apparently the address is invalid. My address is F0:B4:79:62:0B:50, is that address valid? and if not, what do i do?
thx, Connor
