Usb Tethering mac address changes randomly

Hi
I have a ATXT1800, and it connected to a Deeper Network DPN device by USB tethering
my problem is any time I have to restart router or DPN the mac address of ATXT1800 changes by itself randomly, so I have to reconfigure the setting inside my DPN
I can't find where is Tethering mac address even in the Luci to prevent it of changing after restart

Hello,

May I know did you mean that interface "tethering" MAC change at random? or WAN?

I tested on my AXT1800, v4.8.0 firmware, and it didn't reproduce, including reconnect tethering and restart the router.

The interface "tethering" MAC hasn't changed.

Please SSH to router to check (eth3 is the tethering in AXT1800):
ifconfig eth3

please ck this


you can see how many times it changed my firmware is 4.7
the wan is constant, my problem is tethering

Please upgrade the AXT1800 firmware to v4.8.0, and test one more time

I have restarted tethering and the router many times, and the interface "tethering" MAC has always been '46:4A:DB:01:30:C6', please forget it is a randomly generated MAC, but it never changed.

The same issue, nothing changed

Hello,

Please provide a screenshot of tethering MAC:

ifconfig eth3

Hi


ifconfig usb0

Hello,

Here is my AXT1800, firmware v4.6.11, and did not reproduce this issue.

  1. Connect the android phone to AXT1800 via tethering (usb0), MAC address shows below, and reboot

  2. AXT1800 booted up, the tethering link is automatically connected, and the tethering (usb0) MAC address is not changed:

Could you please share your router with us to remote check through GoodCloud?
Please upgrade the AXT1800 to v4.8.0 firmware, and PM me the router MAC address (WAN) and WebUI login password.

Update:

It seems that the interface usb0 MAC has been changed, but the router only restarted. I will check how to avoid the MAC change first.

Hello,

  1. Confirm your AXT1800 interface tethering usb0 is connected to this same one USB modem all the time.

  2. Please SSH to the router, execute the commands :

uci set network.tethering.macaddr='8e:2f:d4:f7:34:46'
uci commit

(The MAC address "8e:2f:d4:f7:34:46" is a virtual created, you can change it what you want, or ifconfig usb0 to get the currently using one)
