Frequent disconnects

Slyder · May 16, 2007, 11:49:05

Hi there, i'm having problems with my IDnet connection.

I've had it for about 2 months now, and everything has been going okay up til now. I've been experiencing several disconnections which involves my Linksys WAG354G Router's ADSL and INTERNET light going off, then back on a few seconds later.

Is there any reason for this? Maybe a few of my settings need to be changed...

Rik · May 16, 2007, 12:03:02

Sounds like noise on your line, which is causing the router to re-sync. Does the Linksys have a log which shows such events?

It might be worth a look at your internal wiring and, if possible, trying the connection at the test socket if you have one. See here for full details.

you mean this?

Rik · May 16, 2007, 15:33:42

That looks more like an intruder log.

This is how a Netgear records a loss of sync:

Thu, 2007-05-03 17:18:50 - LCP down.
Thu, 2007-05-03 17:18:50 - Initialize LCP.
Thu, 2007-05-03 17:18:50 - LCP is allowed to come up.
Thu, 2007-05-03 17:19:30 - CHAP authentication success
Thu, 2007-05-03 21:40:03 - LCP down.
Thu, 2007-05-03 21:40:06 - Initialize LCP.
Thu, 2007-05-03 21:40:06 - LCP is allowed to come up.
Thu, 2007-05-03 21:40:16 - Loss of synchronization :6
Thu, 2007-05-03 21:40:23 - CHAP authentication success

Slyder · May 16, 2007, 15:45:40

hmm.
Then i'm not too sure where i can get to something like that..Is there anyone here with more knowledge on Linksys routers? @__@

Rik · May 16, 2007, 15:53:27

I'm not sure - I'm trying desperately to think of who might have mentioned using one. Possibly Avenger?

If no-one can help, pop across to the DSL Hardware section of ThinkBroadband - I guarantee you'll get an answer there.

Meantime, if you give support a call, they may be able to help you with information from their logs... More importantly, you need to see if you can isolate the problem by eliminating your internal phone wiring.

Slyder · May 16, 2007, 16:12:28

Okay, shall do what you suggested. I've just plugged my cables into the test socket on my phone socket, and now hoping to see any changes.

Lance · May 16, 2007, 16:14:26

I have a linksys router, and it would seem that the logging on yours is the same - c**p.

The only way to log a disconnection is using routerstats.

I would agree with Rik, it seems to be a noise issue, so if you have gone through the things in Rik's sticky (linked to in his post above) I would recommend running routerstats to confirm it is a noise issue. rom there we can then give you the options of what to do.

Lance

Lance · May 16, 2007, 16:16:38

Now you are plugged into the test socket, you should check your SNR margin. If this is much higher then you have a problem with your internal wiring. Alternatively, you may find you have a much higher sync (with noise margin at 6) which will also point to internal faults.

Rik · May 16, 2007, 16:17:13

Sorry, Lance. I knew someone had a Linksys - just thought it was Avenger for some reason.

Lance · May 16, 2007, 16:18:05

I seem to remember Avenger mentioning either Billion or Zyxel???

This is after putting it in the test socket.

Another thing, would it do any harm to leave the phone line inside the test socket instead of the one on the faceplate?

Those are the results. Do you have a 'before'?

You're fine using the test socket. Consider it a temporary filtered faceplate...

Slyder · May 16, 2007, 16:30:59

Nope, i don't have results from before, but if anything, i'll get one soon. I have to go and do something x_x
Thanks for the replies so far!

Slyder · May 16, 2007, 16:32:58

Ah..just had another disconnection x_x.
Would it be a case of overheating? I have had the router on for several days...

Rik · May 16, 2007, 16:36:20

It shouldn't be, routers are designed to be run 24/7 - mine's never over-heated in months of running. If it is over-heating, it's possibly faulty. More likely, that was an electrical spike. Is anything set to switch on around 4:40, eg heating?

Slyder · May 16, 2007, 17:08:38

I'm not sure, if it was a electrical problem, wouldn't the whole router shut off and not just the ADSL and INTERNET lights?

Rik · May 16, 2007, 17:13:10

No, if it's electrical noise being picked up, that would just cause the connection to drop, ie you would lose sync.

Slyder · May 16, 2007, 17:46:56

Okay, i've checked anything that might be set to go off at regular intervals, and i can't find anything.

Another point that might be useful to hear. My dad has on several occasions been pulling out the phone line directly, for what reasons; i'm not sure. Could this have somehow 'damaged' the router or someting else?

Rik · May 16, 2007, 17:49:00

It shouldn't have done any damage, but it might just have caused some noise on the line I suppose.

ReDGryphoN · May 17, 2007, 09:44:37

Hi,

Your downstream margin looks a little low, might be causing a resync from the exchange, not sure if the Linksys router you have is compatible with the DMT tool, I know that the Linksys WAG54GS is ok with it.

http://dmt.mhilfe.de/ for the DMT tool. you would need version 8.05

This tool allows you to play around a little with your target noise margin with the potential to increase you speed and / or make your connection more stable.

Hi, thanks for that link.
I just can't seem to find the port number, nothing else works.

ReDGryphoN · May 17, 2007, 12:05:14

Hi,

Port is always 23 it used the Telnet port.

Username and Password are admin and password all lower case.

I've tried port 23 and it gives an error message, here's a picture link :
