MAC address and wifi

I just bought a MacBook Pro. It was set up at the shop.
When I brought it home, the MAC address showed up as f8:1e:df:e2:d6:71
My Dlink router says it is an invalid address. I've never had the problem with my other Macs and iPod Touches on my home network.
Any idea how I can make it a valid address?

The home network has MAC filtering because our connections seem to drop out from our router all the time.
Very strange that my Airport iD starts with f8 as all my other computers (PC and Mac) and ipod Touch are all 00 addresses.
So I am concluding that
1) I cannot change my MAC address.
2) My dlink cannot accept my MAC address.
I am currently spoofing my address. Which is heaps annoying because I have to go through the process of changing it everytime I turn on my computer.
I have yet to try this Mac on other wifi systems. But I hope I won't run into any trouble with wifi that might need my MAC address.

On windows XP or linux have a MAC adress Change function allow 00 mac adress and another normal mac adress range.On windows 8.1 all Mac changer program dont work.This 2,6,A,E on second adress are not vaild Mac adress. You simply can not use normal MAC
addresses on windows 8.1.When i connect the usb the Pc windows 8.1 recognizes the adapter but the default driver and the downloaded ralink driver the same problem.On windows xp the current driver works perfectly have (Local Mac Network Adress) funktion
and works with the 802.11b hot spot.I got the internet my PC and laptop too public HotSpots and another wifi HotSpots if wont work correctly i can not use neither the windows 7,8,8.1 or 10. Many users have expressed interest in the problem more forums.
The 3. problem im tested in virtualbox the windows 7 and 8.1 on 8.1 (on the blue wifi platform) not show correctly the signal strengh. On windows 7 show this correctly.The windows 7-8.1 Configure/advanced the advanced options on Ralink 3070 the default (windows
driver) somehow downgraded function is less than for Xp. Configure/advanced the advanced options (needs to be upgraded in the future) because it does not advance but rather regressed.
Today it is very common these wi-fi technology increasingly used (hotels,Public Hots Spots,Internet coffe,) growing free bublic wifi projects. The wifi funktions on windows need debugging and modernize.The quality of Wi-Fi is now the operating system
is now a thing order which is not good then the operating system is unusable.

Hi,
For changing the MAC address for Windows 7 is designed with some limitation, we cannot get over it. Thanks for your understanding.
Under Windows 7, the possible range of spoofed addresses for wireless adapters that can be set is limited. To be used by Windows 7, a spoofed MAC address should have 0 as a least significant bit (unicast) and 1 as a second least significant
bit (locally administered) in the second nibble. Thus possible values for the second nibble are limited to 2, 6, A and E.
In other words
MAC address: “XY-XX-XX-XX-XX-XX” “X” can be anything hexadecimal. The hexadecimal “Y”, written in binary format, is Y: “kmnp”, where “p” is the least significant bit;
p=0 --> unicast;
p=1 --> multicast;
n=0 --> globally assigned MAC;
n=1 --> locally administered;
So, actually MAC can be changed to any combination in which p=0 and n=1;
“Y” can be 2, 6, A or E.
So the possible MAC addresses in Windows 7 for wireless adapters:
X2-XX-XX-XX-XX-XX
X6-XX-XX-XX-XX-XX
XA-XX-XX-XX-XX-XX
XE-XX-XX-XX-XX-XX

Reports for Apple devices with SCCM client - Mac Addresses and IP information.

Greetings.
I've been having an interesting problem.
I am currently running SCCM 2012R2 with PKI and have clients installed on windows, linux (ubuntu mostly) and apple computers successfully.
I have created custom report proving me with hardware information for windows and linux machines (Serial numbers, manufacturer, Mac Addresses and IP addresses) successfully.
So far I wasn't able to create any report or even find what table information about Apple computers MAC and IP addresses is stored.
If i go to Apple computer in SCCM using resource explorer under hardware I can see network devices, so that information is definitely gathered by SCCM in some way.
Can anyone help me out with this and maybe I am doing this in a wrong way?

Nice. Only trouble there seems to be multiple entry for same mac address there for same resource id.
So when I try to get them as substring i get multiple copies of same mac address.
But looks like this will work as solution to this problem.
So far I was doing it this way (And i am sure there is clearer way to do it.)
SUBSTRING((SELECT ',' + CAST(t2.MACAddress0 AS VARCHAR(40))
            FROM (SELECT DISTINCT ResourceID, MACAddress0 FROM v_GS_NETWORK_ADAPTER) t2
            WHERE t2.ResourceID = ResourceID
            ORDER BY t2.ResourceID, t2.MACAddress0
            FOR XML PATH ('')
        ), 2, 100) [MACAddresses]

Mac address and Serial Number

Hello all,
my Macbook pro was robbed last weekend, i wanna know if is possible to get the MAC Address of my Macbook if i have the serial number, i wanna try to locate my Mac by that way, but i dont have the mac address, just keep with me the serial number of...
Thanks all.

OK, I know that.
I'm in Chile, and I have contacts on a local ISP, they use for all its connections a relation between MAC address and modems, any other computer can't use that connection if that association is not changed.
My hope is that my Macbook will be use with that ISP, for that the thief would have to give the MAC Address ... so I can get the bad boy name...

MAC address and the CAM entries on the Layer 3 FWSM(Transparent mode)

Hi,
With refrence of Cisco Secure Firewall Services Module (FWSM) of Cisco Press book it's mentioned that
"While configuring the transparent mode in FWSM, it is important to specify the MAC address and the CAM entries on the Layer 3 next hop device of FWSM."
This part of configuration is not very much clear to me please let me know the logic of this things
The following are two examples:
Layer 3 Device A (PFC) at the Outside Security Domain
! IP address of the next hop for the outside security domain
interface Vlan20
mac-address 0000.0000.0001
ip address 10.10.1.1 255.255.255.0
! Specify the IP address and MAC address at the first hop layer 3 interface
! of the inside security domain
arp 10.10.1.21 0000.0000.0001 ARPA
Layer 3 Device B at the Inside Security Domain
! IP address of the next hop for the inside security domain
interface Vlan21
mac-address 0000.0000.0021
ip address 10.10.1.21 255.255.255.0
! Specify the IP address and MAC address defined at the first hop interface
! of the outside security domain
arp 10.10.1.21 0000.0000.0002 ARPA
Regards
Chris

Check the serial # reported by Sys Info against the serial # printed on the bottom of the case. I bet they are not the same. The service center did not change the serial # on that new Logic board to match the REAL serial number of your Mac.
So when you try to go to the MAS it looks like a completely different Mac which is not registered under your Apple ID.
If the above is true, the serials being different, then you need to take it back and have that changed to your REAL serial number.

Mac addresses and switchports

Hi all, am i correct in saying a mac address cannot exist on more than one port on a lan, except for the uplink ports leading to that mac address ?

That is correct. Each NIC will have a globally unique MAC address and that NIC can only be connected to a single port. So, with the exception of uplink ports, a given MAC address can only be on one port.
Hope this helps. If so, please rate the post.

MAC address and hostname

i got a sun ultra 10 and i am getting idprom contents invalid on bootup, but i get it to bootup. The machine does get an ip address from dhcp but will not connect, the mac address is showing fe:ef:ab:ef:ff:ee (which i am assuming is default, or wrong cause of the idprom). the host name is also showing afefeffd, which is also probably wrong, the mac on the case shows it should be 8:0:20:cf:77:df and the host should be 80cf77df
do i need a new nvram to get this to work?

chill dude being rude isnt going to make people help you...
anywyas... you need the host name and password for your schools network
the touch doesnt have its own
you should be able to connect to it by just going to wifi settings on the touch and then it should pop up when ur in school

I want to reserve a static IP address on my Airport extreme. What is the difference between reserving by MAC Address and DHCP Client ID?

I want to understand the differences in the way you can reserve a static address for a device on the network. I had previously set the device itself to an address and then reserved it with DHCP Client ID, which I thought was just the devices static addresss. I'm not sure if this was in fact correct or just happend to work. I know what a MAC address is, but I'm not really sure what the DHCP Client ID is. So it would be great if someone could clarify it, and the difference between reserving address by MAC Address or DHCP Client ID.

A MAC address is a unique identification consisting of letters and numbers in a form that looks like this:
xx:xx:xx:xx:xx:xx
Every network device has a MAC address, which can be found on a label on the bottom or back of the device. Apple calls this the Ethernet ID.
A DHCP Client ID is an optional name that you can assign to a device. For example, on your Mac....
Open System Preferences (gear icon on the dock)
Open Network
Click on Ethernet
Click Advanced at the lower right
You may be able to edit the DHCP Client ID here....for example.....you could enter MJ500's MacBook in the space provided. That would be the Client ID of your Mac.

HT4061 I downloaded an iTunes update on my HP. PC and restarted the computer for the hangers to take effect. Now my pc is locked up. It gives me a client Mac address and no boot file name received. What happened, and how do I get my pc back?

I downloaded an iTunes update and when ashen I restarted my pc it locked up. It says client Mac address 001320bead25, PXE E53 No boot file name received. PXE MOF. Exiting Broadcom pie rom. How do I get my pc back!

When you installed iTunes on your work computer, then connected your iPad to that computer, it wiped what was on the iPad, then put the iTunes library (nothing) from the work computer onto the iPad. You can try copying the iTunes folder from your home computer over to your work computer, but since the apps were bought with a different account, they may not load or update properly.

Printers connected to E3200 USB port - MAC address and IP address

HI - I have a printer connected to the USB port of my E3200. It is working perfectly as a network device. It happens to be an Epson Stylus Photo 1400. My question:
Does this printer now have its own MAC and/or IP address? If yes how can I determine what they are?
I am on Windows 7.
Thanks much!
Solved!

Jake - Makes perfect sense. Thanks. Do you know how I can get the printer's MAC Address? Eliot
It should be on the printer itself. Just look for the sticker. Most of the time it is at the bottom of the device or at the back it should say MAC address or look for the number that looks like this : 00:00:00:00:00:00.

Mac address and device name

Hello,
Not sure how to explain my requirement, but I will try: How can I broadcast my computer name along with the MAC address? In other words, I have a Netgear WNDR3700 router and when I login to see the "attached devices" I only see the assigned IP and MAC for all our MacBooks. The router page shows other devices (printers, shared hard drives) but I want to identify my Mac also by name and not guess/investigate who's MacBook is.
Maybe the pic can help.
Thanks!

Does the device name match up at all with the MAC address? Since you blocked out the MAC address I can't see it but everything after the BRW in the device name looks like a MAC address. Could be the BRW stands for Broardcom something Wireless. Which IIRC Mac's use a Boardcom chip for both Wireless and Wired Ethernet.
