Do you mean MT300N? MT300A should work with mac address changes. ---

After a thorough test, I have to say that MT300A doesn’t support changing mac address in repeater mode. I made some mistakes in my previous test. ---

AR300M is nearly ready. Changing mac address when combined sta and ap in MTK chips seems a problem. Maybe this is because of the wifi driver, not the chips. Just don’t have a clue now. ---

The wifi driver is opensource, so it is possible. But need very good technical skills to debug. AR300M doesn’t have sd card, but it has 128MB NAND flash. ---
