Model: TD-W9970  
Hardware Version: V3
Firmware Version: 20.05.16.01006

Each time my modem/router reboots its MAC address changes. I have range extenders (TL-WR940N) configured to connect this static MAC address and they fail to auto-reconnect due to changing MAC address after reboot. I need to recongigure the extender with the new modem/router MAC address to make it reconnect.

 

I suspect this is due to a new firmware upgrade since I was using the same modem/router - extender configuration for two years and never had such an issue. Screen captures before & after reboot below:

 

Before Reboot:

 

 

 

 

 

After Reboot:

 

 

 

 

Need to reconfigure TL-WR940N

@bilgi 

Hello,

Thank you very much for your patience.

For your case, we would like to get the following information for further analysis.

  1. Can I have a picture of the bottom label with the MAC address?
  2. By the way, since you mentioned that there is a firmware update recently, so Did this issue happen after the firmware update?

Thank you very much.

@Sunshine Hi Sunshine,

 

1) Here is the bottom label of TD-W9970 modem/router

 

 

2) Yes. That is a modem provided by DSL provider Turkish Telecom and only they can update the firmware since there is no "Firmware update" option at the admin panel. When the extender unable to reconnect the DSL modem, I login to admin panel of the modem to control the settings and extre menus like "Easy Menu", "USB Settings" had arrived which was previosly not availavle. That is why I thought the firmware was upgraded.
