I have the TP-Link AV1000 Powerline Ethernet Adapter with the wan end connected to my Comcast modem. On the receiving end, I connected an apple AirPort Extreme. This is to extend WiFi to the opposite end of the house. This works GREAT for a few hours. Then, although the airport shows the green light saying it has an IP it stops sending any signal. All connected devices drop. I have a lot of smart home devices that need a constant connection. When this drops the SSIDs are no longer being broadcast. If I restart the airport it resolves immediately and everything works again for a few hours. I saw that the TP Link has some sort of power saving built in and wondering if this might be stopping the connection?  Or if there is another fix for this?
