Udev allows you to perform MAC address spoofing by creating udev rules. To randomize the MAC address on every boot, set MACAddressPolicy=random instead of MACAddress= spoofed MAC. NamePolicy=kernel database onboard slot path Systemd-networkd supports MAC address spoofing via link files (see systemd.link(5) for details). Note: A device cannot be in use (connected in any way or with its interface up) while the MAC address is being changed. Where XX:XX:XX:XX:XX:XX is the MAC you wish to change to.įinally, to return the MAC address to its original, permanent hardware value: # macchanger -mac= XX:XX:XX:XX:XX:XX interface To change the MAC address to a specific value, you would run:
To randomize only device-specific bytes of current MAC address (that is, so that if the MAC address was checked it would still register as being from the same vendor), you would run the command: The MAC address can be spoofed with a fully random address: The spoofing is done on per-interface basis, specify network interface name as interface in each of the following commands. It provides a variety of features such as changing the address to match a certain vendor or completely randomizing it. If it worked, 'link/ether' should be whatever address you decided to change it to.Īnother method uses macchanger (a.k.a., the GNU MAC Changer). If you want to verify that your MAC has been spoofed, simply run ip link show interface again and check the value for 'link/ether'. This can be accomplished by running the command: The final step is to bring the network interface back up.
Where any 6-byte value will suffice for XX:XX:XX:XX:XX:XX. # ip link set dev interface address XX:XX:XX:XX:XX:XX To change the MAC, we need to run the command: For more information please read Wikipedia:Organizationally unique identifier. Therefore, unless you control the network(s) you are connecting to, use MAC prefix of any real vendor (basically, the first three bytes), and use random values for next three bytes. Any hexadecimal value will do, but some networks may be configured to refuse to assign IP addresses to a client whose MAC does not match up with any of known vendors. The first step to spoofing the MAC address is to bring the network interface down. It will probably look something like this: The section that interests us at the moment is the one that has "link/ether" followed by a 6-byte number. Where interface is the name of your network interface. Both of them are outlined below.įirst, you can check your current MAC address with the command: Then just "spoof" a stable address all the time.There are two methods for spoofing a MAC address: installing and configuring either iproute2 or macchanger.

I saw no concrete evidence that it 'fixes' this problem.Īlternatively, you could look into the tools for MAC spoofing (AFAICT, these all require a rooted phone).

The only useful recommendation I saw on the internet was the obtuse 'WiFi Fixer' app, that is known to work around some problems on early Android wifi handsets.
Here's a post about the problem from 2010:
#Changing wireless mac address software
Too much software (technically incorrectly) relies on MAC addresses as a stable identifier for an endpoint, so this seems likely to cause more problems than it fixes. So it seems very, very odd to generate MAC addresses on the fly like this. Normally a MAC address is burned into the WiFi device. Poking around on google there are a lot of other folks with this problem (MAC address is re-generated on wifi/phone resets).
