Having purchased this kit, I get an issue where the end device (WPA4220) loses connection (both hardwired and wireless) after 3 days.

I have checked the firmware and tried using different sockets and disabling the 'sleep' function to no avail.

I even purchased another unit and this also drops out after 3 days!

I have adjusted settings from the utility app and web browser.

The only thing I cannot seem to be able to do is check and locate the latest firmware for the TL-PA4010 element of the kit.

I notice that there is a post here; https://community.tp-link.com/us/home/forum/topic/204238 although I am surprised that this is not on the TP Download site and also cannot find a PIB file.

Can anyone please assist/advise?
