Hello tp-link community,

The device goes into energy-saving mode after connected network devices are ideling since a while, but does not wake up afterwards, anymore.

Disabling the energy saving mode within the TP link tool does not work, I receive an error message that the attempt failed.

Only workaround is to unplug and plug back in the PA, which works with the drawback of un-powering everything which is connected, as well as this is working until the network is idling again, only.

In this community, the problem was described already:

post #6 is describing a solution with an alternative firmware (tpPLC_Uitility_2.3.4543.9_220620).

I'd like to try this.

So far, I have contacted the TP support. Following their instructions (updating TP link software to the newest version, factory-resetting the TP) did not help. 
Further support attempts (turning off and on the WLAN of the TP) were not applicable, questions being asked (where an when did I buy the TP) had the intention to inform me about the warranty. My specific request of providing the alternative firmware was declined.

As I do not have any warranty anymore, anyhow, and it seemed to work for the user in the linked community thread: May I ask the community if the firmware is available and can be provided to me?

thanks a lot & br,
