Hello, so recently I bought a Wi-Fi extender by tp-link but I came across a few issues.
Here's my setup: I have a wifi router 3 rooms away from mine. I have no problem connecting to that said router from my room, but my connection is poor. So I installed this wifi extender. First installation was smooth, everything worked correctly, the app says that the wifi extender is in a great spot and has great connection to my router. However.. every 3 hours or so, it completely loses connection to my router. No matter what I do, rebooting, unplugging from the wall.. even entirely reseting the extender. Nothing will help at all. For about 20 minutes, there is no way that I'm connecting the extender to my router. But, after those 20 minutes, it just starts working again. It finds the connection and everything is great again.

Keep in mind that in between those 20 minutes I can connect to my router wirelessly without any problems whatsoever. So it's not like the router stops working. And also if I access the extender settings while it's not working, I can scan the area and I'm able to see the wifi connection from my router. And I can connect. But I won't get any internet connection.

Anyone here have any idea what might cause this? Any help would be much appreciated
