Yes ... I got my problem resolved. Now I am getting good service for over three weeks. Check out my current speeds ...
I had to work on the Tel. Exc. worms real hard and then their techies did it for me.
I still do not understand 'Local/Remote Tx Power' settings. Are these set by them or are they the result of some settings? Please comment someone.
I have, a few days ago, upgraded from the DSL-399 to the DSL-599 plan so that my download limit is now 1 GB. Even this is not enough. If I request for the download speeds to be set for 2 Mbps, will I continue to get excellent connectivity and continous service like I am getting for the past three weeks? This is my issue. What I actually need is better upload speeds since mostly I get 150 to 350 kbps inspite of the over 400 kbps shown in the test.
