Hi,

I just bought TL-WA850RE and trying to connect the internet to my laptop and my phone.
The signal on the extender is 3 bars.
Internet successfully connected to the laptop with full signal + fast and stable connection.

The issue is on my Samsung Android Smartphone (i'm using samsung galaxy grand prime) the signal is full, but the connection's very unstable.
Sometimes the connection is fast for like 5 seconds and for the next 5-10 minutes it can't even connect to the internet; and repeat.

attached is the screenshot of the router's status.



.

please help me :(:(
thank you so much.
