TMAC Issue With Wireless Network & Workaround

Technitium MAC Address Changer (TMAC) is unable to change MAC address of many wireless network adapters on Windows Vista and above. Its been observed, and I had quite a few email feedback confirming that, on the same hardware with Windows XP installed, everything seems to work fine!

I also had one email feedback saying that TMAC couldn't change MAC address of Wifi on Windows XP machine after updating drivers. Reverting back to old drivers again made things work.

This issue is observed only on wifi adapters, while you can change the MAC address on Ethernet adapters without any fuss. This tells that the network adapter drivers are actually preventing users from changing MAC address.

A simple workaround would let you change MAC address on most wifi adapters if you want to just make sure your original MAC address is not exposed. You just have to set the first octet of MAC address to "02", instead on what normally is "00".

If the MAC address didnt change, try to disable and re-enable the Wifi network adapter manually from Network and Sharing Center > Change adapter settings (or you can just enter Network Connections in Windows Explorer location bar).

While I am not very sure why it works with "02" I think it has to do with the MAC Address specification which uses first octet to set flags (see image below; courtesy Wikipedia.org)

Setting first octet "02" actually sets the b2 bit indicating that the MAC address is locally administered. Looking at this MAC address thus indicates that the MAC address is changed by local machine administrator. But, its still good if you just want to hide your original MAC address instead of spoofing someone's MAC address.

Another guess on why this works may be due to Windows Network Bridge feature. When you bridge 2 or more network adapters in Windows, the Network Bridge sets its MAC address to the first network adapter added to it with the first octet set to "02". Thus, if the network adapter drivers didn't allow the change, it would make the feature not work.

Just try the workaround if you have this issue.

  1. Hello Shreyas Zare,

    have you found any workaround to change though to an address starting with "00"? It seems that is a windows 7 restriction, believe it worked earlier on XP.

    Thanks,
    Alex

    1. for changing mac address on windows 7 wireless adapter,
      you have to let say 00-50-56-C0-00-01 this mac address, it wont work unless where is 00, on the second place always must be one of this characters A,E,2,6, dose are only allowed by windows 7, so you can chose any mac address but always put on second place on of this.

  2. Hi Alex, the restriction is in Vista as well as Windows 7 wireless network adapter drivers and there is no workaround for MAC address starting with "00". As you said, it works perfectly in Windows XP.

  3. yep, interesting though that it's only restricted on wireless adapters - was able to easily change MAC of the LAN adapter to the one starting with "00"... don't understand Microsoft logic for such restrictions.

  4. Ya, its only for wireless adapters. They must have thought to make it tough for WiFi hackers.

  5. the same with usb lan, on a tethered interface (NDIS remote via usb connection) MAC cant be changed, even with 02 on first octet.
    On the gui program it appear like original MAC and the new MAC like inactive on network connection details.

    ReplyDelete
  6. Because of Microsoft's usage of these bit flags, the possible MAC addresses in Windows 7 for wireless adapters is:

    X2-XX-XX-XX-XX-XX
    X6-XX-XX-XX-XX-XX
    XA-XX-XX-XX-XX-XX
    XE-XX-XX-XX-XX-XX

  9. If you got USB wi-fi device then TMAC wont work on it.

    Secondly, if it doesnt work on your machine, it doesnt mean it wont work on other machines. It might be useless for you in that case but not other people using it daily.

    It depends upon your network config. Like, if you are behind an ADSL modem with NAT then changing your machine's MAC address wont help as the modem is having the live IP. Your machine is in a private network behind the NAT.

  16. Had similar instance with the MAC not changing or reverting to a new adapter profile and won't even restore to original. MAC changed after initial installation and worked fine until windows update. Now it won't even restore to original and keeps showing inactive MAC address after the weird MAC information now on the main screen. You can't do anything with it, for some reason even though the original and changed MAC info does show in the registry. System restore worked one time, then every time after that it was back to showing MAC change fails to change and shows inactive MAC of the changed MAC information, but won't show it Changed now. Tried it on numerous machines running Windows 7 with various wifi adapters from Intel to others and similar results. Any ideas would be helpful. Thanks.

    You already got the version which works on Windows 7. If you are not able to connect to the network with changed mac address, then it must be due to your ISP config. Check this with your ISP.

  21. Hi, I have the problem that with 3 different wifi-usb-sticks, and also with my notebooks built in wifi-card with a changed mac-address I usually don't get into open public hotspots (Win-XP Home SP3). They say, I am connected, but nothing more happens. But rarely it IS possible.
    By chance I noticed in Norton Internet Security, that Microsoft sends out for every uPnP-device some information to a special IP-address, which I don't remember anymore. But I had looked it up at iana.org(?)...I guess.
    Could it be possible, that Windows routine sends the original hardware-mac-address and that routers of public wifi-hotspots can grab this and notice the difference?
    So, then blocking this port for uPnP-devices with a firewall could help?

    You actually didnt tell about the problem other than telling there is problem. If you can take screenshot of the TMAC window when their is issue and email it to me then I can help you out.

    Windows or any software/driver wont send the original MAC address in any case over network. So you dont have to worry about that.

    Well, thanks for your fast response! The surprising thing for me is, that now everything works...maybe because I just intalled a new system from stratch. Before that my problem was, that I just came up to the point where the hotspot wanted to assign me a network address, which I never got. But as soon as I went back to the original MAC-address of my WLAN-USB-Stick, I got a network IP-address and I had internet access. Strange...anyway, thanks a lot!

  30. Hi Shreyas, great program! I seem to be having similar issues as described above, but I have a slightly different goal in mind for my Win7 machine. I am trying to change my MAC address to the same as my Roku device, so I can connect to the internet in a hotel, accept their terms&services, and then change my MAC back to original. Then my Roku will work for 24hrs before having to run this whole exercise again.

    I don't get any TMAC errors, but my MAC does not appear to ever change. I also tried changing the MAC of my ethernet adapter, because I can hard-wire into hotel internet. But it also doesn't change. TMAC does show me the desired MAC address as an "inactive" number, but never active. When I change my MAC, and connect to google, the terms&services page does NOT show up, which tells me it hasn't changed.
    Also when I run ipconfig /all, my MAC is still the original.

    Let me know if you have any ideas! I'd love to get this working. (All other features seem perfect though!)

    Well, it might be possible to get 15 more minutes with new IP that you get by changing MAC address. But, it still depends on the network config, like for example, your browser cookies might be used track your machine and block access. You can try by clearing browser cookies and flash cookies together with changing MAC address.

  34. I have a problem when I try to change my MAC address with new MAC no. started with C0-CB-xx-xx-xx-xx. This MAC no. is belong to Dell wireless NIC card that Authenticate by network administrator to access Wi-LAN in my office(my machine is using Atheros Wireless NIC). There was an error message that says "Error! There was an error while accessing Windows Management Instrumentation (WMI) services. Description : Object doesn't support this property or method". At Wireless Network Connection it won't change at all. Is that mean that new MAC no. is incompatible or what ? What should I do?

    Just try it again with the "Automatically restart network connection to apply changes" checkbox unchecked and manually disable and enable the network adapter. The next version of the software is almost done and it will solve problems with WMI altogether as its not using it anymore.

  51. Since we're on the topic of changing the MAC address, in Windows 7 and Windows 8, the first two digits of the wireless adapter's MAC address must begin with one of the following four possible combinations:
    02-...
    06-...
    0A-...
    0E-...

    1. I remember to have some user feedback with similar issue long time ago. That user had posted the issue on Cisco community (https://communities.cisco.com/thread/7911). It seems that some devices have issue with network adapters not having '00' as first octet of MAC address.

      However, if you see the latest official IEEE OUI file, which gives all the vendor and the assigned number list, you will notice that the first octet is no longer used for flags and that many vendors have been assigned MAC address which start with '02' and many other combinations (just see TMAC vendor drop down list).

    1. If you are unable to change MAC address with "00" as first octet then there is not much you can do. If you could get your computer MAC address registered with your ISP then it could work. Other option is to have a wifi repeater which would increase the range.

    ALL MAC addresses works just fine in my Windows 7 x64 laptop with XP x64 drivers! I do now use a MAC beginning with 00-... . (I share this in your blog because I do like TMAC a lot!)

    For "all" Atheros shipsets (use "v7.7.0.523 (Win XP x86/x64)": http://forums.laptopvideo2go.com/topic/14833-latest-atheros-wlan-drivers-for-windows-7-and-vista-x86-x64/

    1. Thanks for the compliments. This may be a solution for some users. It might not always be possible to use WinXP x64 drivers in certain scenarios.

      But its worth a try if you got the WinXP drivers for your device (with some risk here, mind that only advance users may be able to restore the system if things go BSOD).

    4- In the Device Manager, enable the device.
    5- Check with ipconfig /all that the device is enabled. If so, check if the MAC address changed to the selected value.
    6- Check if there is network connectivity.

    With these steps, I have verified that in order for the MAC address to be actually changed, I need to change the first octet from the built in value 00 to 02, 06, 0A or 0E, as many have noted, and I have to keep all other octets the same as built in. Any change not following these rules leaves me with the built-in MAC address, and with internet access, of course.

    Now, when I change the MAC address to a valid value, I lose internet connectivity (which is via a WiFi router connected to the ISP modem). What I have observed is:
    1- Adding the new MAC address to the list allowed by my router does not help.
    2- Restarting the web browser does not help.
    3- Setting the router to “Allow all wireless devices” (no MAC filtering) does not help.
    4- The output of ipconfig /all, when I have internet connectivity (that is, only with the built in MAC), is
    Ethernet adapter Wireless Network Connection:

    5- On the other hand, when the MAC is changed, the output of ipconfig /all is

    1. From your description, it seems that when you change MAC address your wifi router stops accepting Ethernet frames. I dont know why you are having this trouble. If you know how to use network packet analysis tools like Wireshark, you can check if any ARP request are being sent by your wifi adapter. If they are being sent, see if any ARP response from the wifi router is being received. You can also check if the wifi router is actually routing IP packets with ping command. With such clues, the actually issue can be figured out.

    2. rtl8187 is a good chip, just install the xp drivers from the folder on the cd, and you are done.
      I did change the mac directly in eeprom and this remains if you unplug the card.

  72. Well done! Thank you very much for all the effort you put in writting this precious software.
    Though an advice for those who are on Windows7 with a USB wireless wifi:
    -1) first you need to disable and remove your delete your wireless network from (Control Panel\All Control Panel Items\Network and Sharing Center) then you need to delete registry entry using the "Action" menu in Mac Address Changer (Delete Network Adapter from Registry) (note:::: remove only you Wireless USB adabter and not the cable connection network!!)
    -2) remove your USb wireless key from your computer then restart your computer.
    -3) once window has started now plug in your usb wireless and then let windows install the necessary driver.
    -4 run Mac Address Changer software.
    -5 make sure to tick all (Authomaically restart...; Make new Mac... and Use 02 octet...)
    - click on Change Now!
    It did work for me after good luck!

    1. Thanks for the compliments. What you did essentially is reinstall the drivers. It could have been done from Device Manager. While, this installed the drivers Windows 7 has stored of your wifi network adapter and worked for your machine, it may not work for others.

  73. To use 00 octet, use older Win XP drivers. The first octet "problem" is related to Vista and Win7 drivers (Microsoft will not verify WLAN drivers for Vista or Win7 without the first octet restriction).

  74. Great program, especially "preset" feature where you can change all parameters (mac, ip address, gateway, dns) with only one click. About changing mac address in Windows 7, this is not because of this program but because of drivers for windows 7. When I was using windows 7 and have found one (i think that it is modified, or just older version) driver for my alfa 036h (rtl8187) usb wireless card, under which spoofing worked.
    Thank You very much.

    modems do not use mac addresses, mac address is used in LAN and WLAN i.e. Local Area Network and Wireless LAN, so you cannot change mac address in modem.

    Very functional program, many thanks author for making it. I've one suggestion for making it even better. It will be great if You can add functionality in preset option so to be able to change computer name (as seen on the network) along with changing other parameters. Computer name, without restarting pc can be made with command line utility named "baptize".

  78. Thanks for your awesome work!

    I have windows 7 Ultimate.
    Intel(R) PRO/Wireless 3945ABG

    “NetworkAddress” key value must be added/changed in both \CurrentControlSet and \CurrentControlSet1 then any MAC works on any of my Dell machines. This may be a Dell specific issue. When updating BIOS, I also had to delete a key in both locations before the installer would startup.

    ALSO

    I retrieved Version 11.X driver from the dell ftp site.
    "http://ftp.dell.com/network
    /Intel_multi-device_A13_R171131.exe"

    >>>>>>>>>>>>>>>>>>>>>>>>>
    The Intel site has the following disclaimer:
    The Media Access Control (MAC) address is hard-coded on Intel® wireless adapters and cannot be changed.

    Some third-party software applications can “spoof” a MAC address to a different address, but for security reasons, Intel does not support this practice.

    Beginning with 12.x wireless driver package, the possibility of “spoofing” the MAC address was blocked to prevent this practice.

    Replies
    1. Once the MAC address is changed successfully, all the outgoing frames will have the new MAC address. The original MAC address will never be known to others.

      Secondly, MAC address is used only at data link layer ie. Ethernet. So, your MAC address is seen only in the local LAN network and doesn't go beyond the first router (your gateway). So, your MAC address cannot be known to anyone on the internet.

      VPN works at higher level and has nothing to do with MAC address.

  82. Ok, i have a Realtek RTL8191SE 802.11b/g/n WiFi Adapter, the MAC address normally starts with 1C. every combo i try fails to connect to the internet, I don't even show up on the home network sometimes. i have tried to manually change it but it tells me that I have to have 02 at the start, but every 02 will not connect to the internet/network. My computer keeps getting locked down by a hacker, I have reinstalled my Windows Ultimate like 4 times, and after about an hour of being online it gets locked down again and i have to start all over again. (format and reinstall) The only thing I can think of is that they have my MAC and when its online they see it and lock me down. I NEED to figure this out to stop it. i am scared to be online for too long. and a lot of what i do is online. Sometimes its longer and sometimes its quicker. I don't have the money to buy a new wireless adapter. Why cant I connect to my home network/internet when I change my wireless MAC? Filtering is good, network is good, router is good, password is good. Im lost here, please help

    1. Well, I don't think your machine getting infected has anything to do with MAC address being tracked. What you need to do is following:

      1. You need to format the machine once so backup all data.

      2. Before you begin to format, use the windows bootrec.exe tool to overwrite the boot sector. This will overwrite any virus which has infected boot sector. (google for more info about using the tool)

      3. Use command line (cmd) and on all drives you have find any hidden file called autorun.inf (use dir /a c: command). Delete all the inf files you find in the drive root.

      4. format all the usb flash drives you got or atleast delete autorun.inf files from them as explained in previously.

      5. Delete all the EXE files on your drives or your backup (viruses can easily infect exe files like setups/drivers stored on your hard drive). Download fresh setup from internet. If you have used pirated windows ISO, download original ISO from internet.

      6. Format the machine and enable automatic updates.

      7. Before connecting to internet on fresh formated machine, disable file sharing on your LAN card options. You have to uncheck the Client For Microsoft and File and Printer Sharing protocols installed on your LAN. This will make sure that before the patches are installed, you dont get infected with worms on your network.

      8. Make sure you use updated browser. I would recommend you to use Firefox with NoScript addon or Chrome Browser.

      Best of luck!

    1. Thanks. I might add feature to change machine name in next release.

      No site on the web can read your MAC address. Your MAC address doesn't leave your local area network. Sites mostly rely on multiple techniques to restored the cleared cookies. They use flash cookies (which are difficult to clear for normal users) & ETags (just see wikipedia page for it).

      Delete
    5. Welcome. Well, there are a couple of ways sites can find out location.

      Most use paid databases which tells a rough location based on IP address (you can check sites like ip2location.com which sell such databases). I dont exactly know how they create this database but, mostly they get brief info from WhoIs records of the ISP which are assigned the IP address ranges and from certain sites which take user registrations and keep user's IP and the location he/she entered in the form.

      Another way is using WiFi access point locations. Every time a browser asks you if its ok for the site to get your location and you click ok, your browser sends a list of all access points your laptop is in range with. With the MAC address of all the access points and the database, services like google maps can pin point your location to +/- say 25 meters! And with latest android devices which got GPS, you tell not only your location, but also the locations of all the access points in your range! And you wondered why Google street view cars were snooping upon wifi data!

    Perhaps someone can help me with something else. Recently, I no longer see the "Local Area Connection 2" in the menu, even after refreshing or restarting the program... although it was always listed for months of using TMAC.

    The link status was always "Up, Non Operational" just like the 2nd wireless connection, so it's probably irrelevant... I'm just curious as to where it went.

    not really a query for help, more a quick note: I have read through all the comments and posts and agree with a fair amount. It is nice to note that there are free software developers who are writing quality software and providing such a decent service, great stuff! I use your program as I have software whose registration depends on the mac address of the NIC it is attached to, which is fine when I am using it in wired mode, however when I am using it via wifi the same software fails as it detects a differing active MAC address, by changing the MAC address of the wireless card to the same as the wired NIC I can therefore work as usual, and unlike paid for options this actually works.

  112. Hi Shreyas !

    Thanks a lot for this software, you're a genius ! Excuse my poor english ('cause I'm french, and as you know french people are bad enough for/with other languages ! lol) but I really wanted to thank you. For your information, the program works perfectly with my (win7 - 64 bits) Wifi computer, with any restriction. My MAC adress begins with 08, may be is it a reason/the reason why...
    I just can say it works everytime... none fail... and it's great ! Go on Shreyas, YOU're great !

  113. First off, amazing program! Been using it for years now. Love it!

    One dilemma, though. I have a laptop with a Realtek RTL8188CE running Win 7 x64 and when I spoof the MAC address, I cannot connect to wifi networks (both secured/unsecured). However, I installed the Win XP x64 driver and it worked but only for unsecured networks. Win Vista x64 doesn't allow connections to either as well. They all just fail at connecting. So, essentially, it fails to connect across the board except for Win XP x64 unsecured wifi. Any ideas? And I have tried using 02, 06, 0A, & 0E.

    Thanks in advance!

    Regards,

    John

    1. Thanks for the compliments. Well, I haven't seen this type of behavior but, can you describe what you mean by "fail at connecting"? I am guessing that the MAC change was successful but you are unable to connect to an access point.

    2. Exactly. The only access points I can connect to are the unsecured ones, which, is obviously unfortunate. And the above is only possible via the Win XP x64 drivers. Oddly enough, if I use my external WiFi dongle, I can change the MAC just fine.

    3. This is an odd situation. I have had one similar feedback. But, I never got a similar situation to test with.

      My guess is that some new wifi ap firmwares are made to reject mac addresses with the "02" bit set. A programmer will think that this will secure the network but, its simply not that easy!

    4. Ahh but that's where it gets confusing. You see, the AP accepts connections from the spoofed MAC of my external wifi adapter, an Alfa adapter that is essentially a modified Realtek RTL 8187. The interface is USB. I'll have to keep messing around with things and if I uncover anything, I will let you know!

    5. Your wifi adapter is really annoying! Let me know if you find anything.

  114. At first MAC address didn't change to other except 02xxxxxxxxx, but later I installed CommView for wifi and its driver for wifi. Then I was able to change the MAC address without restriction.

    1. That's one interesting info. It needs to be confirmed on multiple machines to confirm.

  115. I love the program, and i can confirm that you still need the first octet to 02 in Win 8 x64...
