I tried everything that described in this topic. But my range extender keeps losing connection with router.
So according to the points in the article:
1. LEDs are disabled when it occures, except for power LED.
2. I can't login to web page since it connected to my tplink id.
3. It happens about 5-7 times a day. Sometimes it become fixed by itself, but sometimes it needs reboot.
6. I use only 5Ghz signal on both router and extender.
7. It didn't work fine from the start. I bought it a week ago.
8. I am not sure is it related to big traffic since sometimes it loses connection even without large traffic and sometimes it keeps connection with large traffic.
