Many many many dropout and disconnections

Post by clee0syz » Mon Feb 15, 2010 2:57 pm

For the past week had a few dropouts but came good again. Since last Friday 12/2/10 I'd many dropouts and disconnections. The ADSL light ont modem slow flash, fast flash and then off or hard on for a short period then repeat. If it is hard on it may last for less than a minute or for a few minutes and then repeat the above. Turned the modem off for 15 minutes and on again with no result. The modem was connected to the wall directly with no filter/splitter. There are no other equipments connected to the wall socket. I've no Foxtel etc. The cable is what comes with the modem. Unable to get on the net at all. If I'm lucky I have a few minutes. I desperately need help. Any idea what is the problem?

Tech Support gave me the most stability profile but it's still no good.

Does it coincide with a rainy spell when underground telephone line joints get a soaking? What are the noise and attenuation figures reported by your modem? And is the phone crackly when you listen to it? A stability profile is an attempt to give you a bit more headroom for line noise. Drop outs are usually local affairs.

Thank you for the response Dazzled. How do I do the noise and attenuation figure report by the modem? The phone line is noisy. We had some rain and the ground was wet. I'm currently using a public computer.

You use the browser to enter the modem, in the same way you did when you first configured it. (Depending on brand, it may live at 192.168.1.1) Post the model if you don't know the address.

Once logged in, there is a status page which has the results of the line tests that were made when you last booted the modem. Look for rate, attenuation and noise margin (SNR).

A noisy crackly phone that has "static" is always a reason to log a phone fault. Curing that will probably cure the drop outs as well.

Thank you Dazzled. The ADSL light has come and stayed on. As a matter of interest, what are the acceptable Noise Margin and Attenuation levels? lost my piece of paper. From memory the Noise Margin was around 14-15 dB upload and down load, the Attenuation was 38-44 dB upload and down load. Thanks again Dazzled.

Attenuation varies with distance from the exchange, typically 13-14 dB per km, so we would have to know the distance to decide if it is excessive. You have plenty of noise margin, probably because of the stability profile. If wet weather affects your phone again, report it when the trouble location is still findable.

What is the acceptable noise level?

At a minimum, 6dB, the profile you are on aims for between 9db and 12dB.

I can't see your service connected at the moment. The last connection was 11am - do you normally leave the modem on all the time?

When it's not in use I turn the modem off. Should I do that or should I leave the modem on? I'll turn it on tomorrow morning.

Most people leave their modems on at all times but there is nothing wrong with switching them off regularly (overnight or during vacations).

Yeah I've been having problems with drop outs lately too. Sync is maintained when the connection dies, though. Planning to do an isolation test tonight when I get home. See this thread at whirlpool for details:

The line connecting to the 2nd socket is causing the problem which affect the main socket. When the man he disconnected the 2nd socket so that the main socket can be used for ADSL access. I did an isolation test and the modem took a few goes to connect after I turned the modem off for 15 mins. Once it's connected it was good. I then tried connecting the phone then it would'nt connect. After a few goes I did the isolation test again and this time nothing works. Does that mean that I can't have the phone when I'm connected? It's more than a week coming to 2 weeks now since I have any decent service. why is it it was good for a few days and now I've so much problem connecting? Now I have no 2nd socket, no ADSL connection and out of pocket. I've lost out on every aspect. Any kind soul out there able to help resolve the problem?
