I am using tcl uhd android tv and most of the time it wont connect to the wifi showing "disabled" or "saved",meanwhile other devices are working fine. I have checked there's no mac filter on it and tried forget network then reconnect but still i wont connect.

Does RX optical power has to do anthing with this? My router setting is showing -27.70dBm right now(Referred value:-27 to -8dBm by my ISP).should i contact my ISP or factory reset TV?
