I have JCO4032 ONT from jio.
I have been facing very low signal issues with it.
It's not usable even after a single wall whereas earlier I used to get much better signal with previous ISP ont on single band.
Has anyone face such issues?
Unable to get a separate wifi AP due to lockdown so checking here to see if there's anything to try for fixing this.

Current Firmware SRCMTF1_JCO4032_R1.10
 
You can't do shit my dude. There are no advanced wifi settings in the gateway. Btw, I have the same model
 
Have these new black JCO4032 dual band ONTs less WiFi range/performance as compared to old white JCO500 ONTs ?
Have anybody tried/compared both ONTs WiFi range?
