If you are an exclusive BSNL broadband user, you might not have attached the telephone to the phone line.  I have connected my Netgear modem to the DSL/Phone line splitter and left the other connection floating.  Lately, when I noticed that the Netgear modem was not able to make the connection with BSNL servers, originally I thought the telephone line is dead.  To my surprise the telephone line was fine, but I perceived the lines to be little noisy.  I made a complaint to the BSNL portal and as usual nothing much happened.  Accidently, I had to connect my telephone to the splitter for making a local call.  To surprise, the Netgear modem managed to connect to the server this time.  So, the hypothesis is;

When the telephone line is noisy, attach the telephone to the splitter along with the modem connection to get connected to the BSNL Servers.  Most likely it could be because of the Reactive load offered by the telephone on the phone line ends up conditioning the Phase modulated signals for the Netgear modem to connect to the Servers.

During Raining Days, BSNL broadband line gets little noisy. I used to connect only my router and never my land line phone in the phone line as I use the BSNL telephone line only for Internet access. Lately, I noticed that the Netgear router having difficulty in establishing connection with the BSNL server whenever it was raining or the phone line is noisy. The “i” indicator keeps blinking in ORANGE color and never stabilizes into a GREEN color indication. Having the “i” indicator blink made sure that the link exists. When I wanted to check the condition of the link (telephone line connection), I connected the BSNL telephone to the splitter port which splits the telephone line to the router and the telephone. When I lifted the cradle, I could notice that the telephone line is little noisy. When I was wondering when and how to make the complaint to BSNL, surprisingly the Netgear router made a stable connection with BSNL gateway. I have used this hack several times, whenever the router (modem) had difficulty in establishing connection.

One theory behind this could be the “loading” effect of the telephone on the telephone line which is subsiding the noise ripples coming over the telephone line.
