I have got bsnl broadband connection a week back.
It has been continuously getting disconnected for every few minutes.
Though it shows that internet is connected in the windows task bar, no sites open after a few minutes of connecting the internet.
So, i understand that internet is disconnecting for every few minutes.
Whatever i do, i cannot reconnect the internet.
I have to restart my system to connect internet again.
i have set the hang before idle time to 'never'.
I have also set thunderbird to check for new emails every one minute.
I am using DNA-A211-I modem
I have contacted the BSNL exchange people.
They asked me to check for viruses.
I have checked the system and all hard drives, operating system with latest version of avast anti virus.
I didnt find any viruses.
check your LAN card.,....ethernet connection
if not , write a complaint to bsnl office....they will replace ur modem.....
other way is check the point on ur pc/laptop where the router wire is connected.....it might be loose.....
all the best
