I'm one of the developers working on the Serval Project and we're looking at using the Huawei Ideos U1850 as the default platform for our Android development activities.
We've purchased a few phones from one of our local resellers here in Australia.
We have noticed that a number of the devices that we've sourced from this supplier all have the same WiFi MAC address.
Specifically the MAC address that we're seeing is as follows:
00:90:4C:14:43:19
Multiple devices with the same MAC address is causing us some issues with our development work and so we have two questions:
The idea of a MAC address is that they are intended to be globally unique identifications. I am not sure how you are seeing the same MAC address across multiple devices, this should never happen. I know it perhaps does not answer your question but it should never happen in the first place.
None the less, you can try MAC address spoofing, and a quick Google search reveals the following link: http://www.robmcghee.com/android/changing-the-mac-address-on-android/
