4 days ago new engineer visited my home for the dsl line drop issue.
I had no faith in him coz previous 4 visitis of other engineer had no sucess, but i let this guy do his things coz it was his first visit.
He started doing some changes in the configuration and while doing sso he was cursing the previous engineer, that idiot did not do this and that. He also called the airtel center and complained that the previous guy did not do so and so things.
He said that now i have done the required changes and i should check now before proceeding for any further actions.
He then left and to my surpise in last 4 days i did not had a single disconnection.
In 4 days i should have had at least 50 disconnections, but not a single disconnection so far.
So i can safely say that with proper learned engineer doing your installation or changes, even beetel 777VR1 can work like charm.
Now i dont feel any requirement to demand
Huawei or
D-Link as beetel works just fine.
