Model : TL-PA4010KIT

Hardware Version :

Firmware Version :

ISP :

Hi,
I am using a pair of powerline extensions - TL-PA4010KIT. The hardware version is V1.1

Of late, I updated the firmware, wrongly, with the one that is targetted for HW V2. The firmware update was successful and I did it for both of the pieces.

But, now I see few issues:

1. I see connection drops over some time - say few hours.
2. Poor connectivity - Though they are connected, the data rate drops significantly with lot of interruptions
3. The LEDs are always glowing irrespective of the activities. I can switch off the LEDs from the associated application, but it is not showing data transfer activity that I used to see earlier with blinking LED.

There has not been any change in the electrical network.

May someone help me please? Is there a way I may go back to the earlier firmware? Or eliminate the troubles?

Thanks in appreciation
