I have several TP-Link AV1000 for ethernet only. We dont use WiFi in my home. The version range from V2 amd V3. I get intermitent internet between 830-10am. It cuts out random times. One day it could be 5min or up to an hour. I called my cable provider and modem company. No issues there. When internet is out I connect my laptop directly and get good speeds. I've narrowed it down to the the adaptors. I've re-paired them  and changed the "Host" adaptor coming out of the modem 3 different adptors. After 10am my internet works great. So confused here...
