MT300N - Wifi automatically disabled after MAC clone [Workaround/Solution: Use Upper case letters]

ravenize · 2018-04-03T00:45:39.743Z

Wifi turns “off” after cloning mac address. How to fix this?

Could you show the log? And which firmware version do you use?

alzhao · 2018-04-03T02:57:46.915Z

which firmware are you using?

If you are using a very old firmware it may have problem when cloning mac address.

You can upgrade your firmware to the latest and have a try.

openwrt-mt300n-2.264; was one of the first things I had did; Just to be sure I am going to test once again.

Yes this is still occurring with the latest V1 firmware.

SOLVED I had found the work around; use all upper case letters, not lower case; and I used the advanced configuration to set the mac. No more auto-disconnect. I also used official mac addresses listed by the windows program, TMAC. Technitium MAC Address Changer | A Freeware Utility To Spoof MAC Address Instantly

Upper case letters work in the “Internet Status GUI”
So far, only the Factory default MAC works with lower case. or at least is shown as such in the menu.

I am not sure if this is because lowercase or uppercase.

But DO NOT use Luci to set up mac addresses.

MT300N and MT300A’s mac address for wifi cannot be change freely.

When you have multiple VAP (STA) interfaces, the mac address can only be different in last 3 bit.

For example, if you are using repeater, then you will have two interfaces for wifi. You cannot just change mac address of AP or STA without changing another.

If you use GL UI, then this will be dealt with automatically.

Ah thank you alzhao, im not using it as a repeater, but good to know. Thanks.
