bsnl broadband connection drops, freezes after system idle

[imranka]

Hi,

I'm new to this forum. Hope I'll get my solution from here.

I'm facing a problem from last 3-4 days. I have 500C+ connection which has 2-8 nightime unlimited. So, usually I keep the machine on in the night and using scheduler download stuffs through torrent. No problem in that, fantastic speed and all that. But last few days, checking the machine, I'm seeing that my internet connection freezed sometime in the night. The 'internet' LED in the modem which should be blinking if data transfer occurs is not blinking, rather its stable. I'm running kubuntu 7.10.

So, again I've to do,
sudo pon dsl-provider
to fire up the connection.
This problem only occuring when I'm not using the machine, that is in idle state.

I checked power management, but that is not stopping the connection.

Yesterday, I kept the

tail /var/log/messages/


on whole night, but that didn't show up any interesting messages from which I can debug. One line I got though in the log message which comes up even when the connection is allright, so don't think its related to the problem, but this may be interesting:

Timeout waiting for PADS packets
pppd[4347]: Unable to complete PPPoE Discovery


I tried using a script to keep pinging google.com every 15 minutes, but that didn't help me either.

Even I got disconnected from the pidgin instant messenger.

This problem has just started a few days back and I'm feeling like the problem lies in the modem or the process.

Any help or pointer?

Well u might be new to this forum, but certainly u dosn't looks new to computer science, i can give u some hints but since i did't use Linux it upto u only to implement this in linux.

The author of "Imran's Broadband Helper Utility" has said in his program:
"your service provider can implement a program on server side which can reveal that wheather you are opening some web pages at some fixed duration or not, and if not they often throttle your bandwidth or simply disconnect your connection (downloading a big file using utorrent of fdm is not opening web pages)"

I firmly beleive this is the actual resason behind "Torrents goes dead between night unlimited period".

for more info, see the thread:

Only Pinging(ping protocol) is not enough, try to open web page(not from the cache) at about 1-5 minutes fixed interval.

Hope this may solve the problem.

Well, thanks for the reply. I'm reluctant to use the utility, but I'll try out on my own to write something that will keep opening any web page in a short interval. First time when I saw "Imran's utility" I was like :O because my name is also Imran .

Now some observations:

Today, I wake up in the night twice just to check whats going on:

> I left the machine at 12.00 AM

> I checked it at 2.00 AM

During this 2.00 hours idle period the connection didn't get frozen!

> Then I checked it again at 3.30 AM

The connection was lost. I restarted the connection

> I checked at 7.30 AM

The connection was still on. Though idle for 4 hours!

So, just keeping system idle may not hangs the connection. Something went wrong between 2.00 AM - 3.30 AM. Maybe power fluctuation or total power off... I don't know. Ok, No more playing Sherlock Holmes.

Current IP Check
Check your IP, whenever the connection drops and reconnects.
When BSNL will change, the Dynamic IP cannot be forecast.
Can happen any time. Some modems reconnect automatically,
but some others you have to re-activate again.

So, how to get around this problem, any clue?

 

[superprash2003]

ip changes typically once in 24 hrs.but since many reboot modem between 2 and 8 am.. ip shouldnt actually change unnecessarily unless you have frequent disconnection due to a bad line, low snr etc

 

[imranka]

The problem is solved. Now I changed the cron (scheduler) to run the script every 5 minutes, before that the time gap was 15 minutes. Now, the connection is not dropping. Thanks for your helps.

Otherwise you should make redial attempts to more than 100 and time between redial attempts 1 sec in your connection properties > options. But remove the tick from Prompt for name and password, certificates, etc.So even if your line is droppen and it tries to regain due to power fluctuation, till then it will keep redialling and connect automaticaly when it gets ready.
