Mediatek device - changing MAC address on reboot - Have a device always detected as new device

dfontana59

I have a tablet which is a Chinese made tablet, Brand name is MediaTek. When ever it is turned on it is always detected as a new device in the Fing app. Nic manufacturer always different and I believe it is detected with a new  MAC address. What is going on?

Does the device have a rolling MAC address feature?

Hi @dfontana59
The vendor mentioned also makes the graphics cards for Android mobiles. It may be the case, the device has its own NIC card which is able to change the MAC address. MediaTek is graphics card manufacturer we believe. 
What is the manufacturer and the device?

Hronos

MediaTek make a lot of hardware, even SoC for mobile phones.

t gets powered up  during the boot process comes up with a Big Mediatek across the screen, I therefore assume Mediatek made the tablet. I could be wrong, the documentation that came with it, was just a quick start guide and I do not have the box any longer

It seems like the device is changing MAC address.
I have seen some more information on this on the web when searching for mediatek devices changing MAC address.
If we had a bit more information about the device, I could help you search around further for more detailed info on fixing. For example:
https://discuss.96boards.org/t/mac-address-on-x20-keeps-changing/1114
I'm not sure it's on the Fingbox end -> seems it could be a common issue with the Mediatek devices configuration? Changing MAC address on every reboot? 

I was thinking to move this to devices/security and focus on Mediatek changing MAC addresses rather than Fingbox to try and get more help on this thread from other experts. What do you think?

Anyone know more about Mediatek devices @pwmeek @kltaylor @hronos @Marc @Pixelpopper

I had an Ulefone T1 device powered by a MediaTek SoC, but it didn´t present that behavior.  It's quite interesting.

This is a common behaviour by some devices I've got a media server that does the same. It not only confuses Fing/FingBox but also fixed IPAddress allocation using DHCP servers.

I'm familiar with the brand, not-so-much with the device.
Although I will say that if a network device changes MAC address on power-up, I'd think again on whether I want it to access my internal network with access to the internet.
If this was a device that I owned, I would isolate it to just the guest's internet network and make sure it never touches your internal LAN.  Maybe I'm a bit paranoid, but if it walks like a duck and quacks like a duck ...

Could this be an issue with Android randomizing Mac addresses? See thread...  https://community.fing.com/discussion/910/android-10-random-mac-addresses-seen-by-router

If you think it will help, I'm for it, as it is I have over 100 devices in Fing app because of it. I'm all for anything that helps me fix it.

@dfontana59 @Marc
I don't think this would be related because we've sent out a fix for it!
https://community.fing.com/discussion/1796/mac-addresses-are-back-on-android-10-mac-is-back
MAC addresses should be back.

MAC addresses should be back. 

It did help me see some information the last 3 octets of the MAC address are different, MAC manufacturer  is the same for all my ghost devices what is Inpro Comm as detected by FIng app, name of the device is different.

I will list some of the device names:

Huawei / MediaPad 7 Youth, Sony / Xperia XA Ultra, Alcatel / ONE TOUCH 6030X. Those  were just 3 of the devices.

Hope this helps someone figure it out
