well Bsnl is too smart and shrewd if they provide 500c as in Ur case then the speed is slow because it is a combo plan and U r getting two lucrative things simultaneously and as in politics U don't get laabh ka padd similarly how can U expect speed from them but here is a solution If Ur plan is three months old then U can change Ur plan to Home 500 plan and U certainly get satisfactory speed plus more than 1.5 gb as well!
I've a question too what's this Rep power is it necessary then be benign to me!

unk:
Don't configure just choose default settings and rest assure U'll get good speed coz in most of the time default settings are more than better !
