I use internet via turning my mobile's hotspot on. my primary browser is Firefox. since past few days, i'm unable to access internet in my whole (including IE, Crome, IDM etc.) laptop but my laptop is able to successfully connect to my mobile's hotspot and it is still showing "internet access" [file sync between my laptop and mobile is also working good which means that my laptop's and mobile's wifi related items are ok ]. my mobile is able to access internet so there is no network problem from my ISP side.
I have Epic privacy browser also. it has a feature of "epic encrypted proxy" and when i connect via this feature, i'm able to access internet in epic browser only.
