Airtel – Worst network speed

Worst network speed
Its been more the 4 months a new network tower was installed seen then the internet speed within 1km is way to good but cross a certain distance like 1km the speed become so worst that i can even find a question in google. To was a video in youtube or a reel in Instagram is like a dream for the users. Before the new tower was installed the speed of the internet was perfect all around.
I have register complaint in the airtel thanks app more then 10 times but my problem is not yet resolve.
So with this websites if i could find solution to my grievances then it would be pleasured by not only me but the other public of my city.
