Installed airtel wifi in my flat and Installer is saying you can’t access router

Can you not access the airtel router web interface?

Like 192.168.0.1 thing?

Cause as a cs students thiss seems concerning to me..

Cause you should be able to access router and put firewalls and security as per your needs and if company is gonna do it all

They can easily track our activities and all

I personally put of dns and firewalls in my home router so everything is invisible to ISP.
