2 android tablets have the same MAC address I have bought 2 DGM android tablets (OS - Google Android 4.0) and whilst setting them both up (at the same time) the wifi connection kept dropping.

I checked the MAC address so I could assign them a static IP address from the router, but noticed that they were both the same on the tablets.

I'm no whizz when it comes to IT (I know the basics), but I've searched the web for what can be done, and I don't understand any of it - BusyBox, rooted tablet, MAC Address spoofing.

Can someone please help me out - or point me to some (easy to understand and follow) tutorials?

Thanks a lot!
You didn't name your device -- but most likely got some China import. There were some readings a little time ago about this issue. Normally, a MAC address should be unique to the device -- the producer probably wanted to save some license costs...

Nevertheless, that background isn't going to help you much. There are some apps available on the Playstore which allow you to change the MAC address (search the playstore for "mac-address" to find them all), like e.g. Wireless Mac Changer or Set MAC address. Note, however, that all of them require root access on your device.

The only alternative known to me would be to return the device(s), explaining your reason (see above), and ask for an appropriate replacement.
