Thread: Frequent ADSL Disconnections with WA1003A

I've been using this WA1003A router for nearly 2yrs now without any issues, I'm on Home1000 plan(2Mbps/384Kbps), for a couple of days the ADSL led on the router is frequently going offline but the connection stays alive(pppoe), until i disconnect and wait for a few minutes it doesn't come back up, it blinks but doesn't become steady.

Here's my logs:

Modem Status
Connection Status Connected
Us Rate (Kbps) 864
Ds Rate (Kbps) 2048
US Margin 6
DS Margin 18
Modulation GDMT
LOS Errors 0
DS Line Attenuation 15
US Line Attenuation 3
Path Mode Fast Path


DSL Statistics

Near End F5 Loop Back Count 0

Now, I've noticed that the US margin(SNR) and US line Attenuation stays at 6 and 3 all the time, but the DS margin(SNR) hovers between 12-31(if the phone is used it gets stuck to 26), the DS line attenuation is also fixed at 15.

After 5mins:

DS margin is back to 31

My connections are done properly(wall socket to splitter, from splitter to modem and another telephone splitter), there's a slight noise in my line(very faint but increases sometimes).

This issue happened once before but it was due to bsnl servers and got fixed one day later, but this time it won't go away.

Now the weird thing is that for both Attenuation and SNR DS and US are totally different, is this normal

(I pull about 80-100GB every month from BSNL , so maybe they are doing this??)

Suggestion 1 ;

Get your power adapter replaced.
After a period of time the Electrolytic condenser might have dried up, giving unsteady voltage.

Suggestion 2 :
If you are downloading in WIFI mode,
change to Lan mode and check stability.
Disable WIFI in modem.

Suggestion 3 :

Reg noise in telephone.
Either BSNL line is nosiy/crackling sound etc.
Check contacts for rusting/blackening/high resistence contacts/oxidization .
A new short cable RJ11 with new connectors may help.
Or
Data signal "Hiss" breaking through.
Change ADSl splitter and try
( Only two coils and two condensers inside. condensers might be leaky!)

Feedback.

Ok, I'll start with the modem power adapter first, I don't have wifi enabled so that's not the issue here, about the line noise, its there, a faint crackling noise as you said, now how do I check the contacts? I've changed the RJ11 cable so that's again not the issue here, btw- I have concealed wiring in my house, so there are two extra junctions in the line connecting the adsl splitter and the BSNL post, also the phone line runs parallel to the electrical lines due to this, however this had never given me any issues so I doubt it'll bother me now, I'll check the joints tomorrow.

If I want to change the ADSL splitter do I need to specify any values? Or just asking for an ADSL splitter in the stores would do? I've never changed it before.

About the Difference in US and DS values for both SNR and Attenuation, is that normal?? Could it indicate a faulty modem?? This is today's log:

Modem Status

Us Rate (Kbps) 864

The difference is disturbing, I'm no specialist but somehow I think that if the line is noisy then SNR should be more or less identical for both US and DS, as if the noise goes up during uploads, also the same with Attenuation, could this be a faulty modem, I've been using this modem for 3yrs in a row now and it's kept on about 12-18hrs a day at an average.

Yesterday I was playing an online game, I played from 11PM to 2AM straight, no issues, then I disconnected and reconnected at 2:10AM and immediately I got dsl sync issues and it kept on happening through the night. I suspect BSNL at this.

@tkin
ADSL splitter:
.You can take the present unit and show to the electronic/computer dealer.
cost may be around Rs 50 to Rs 100/=

As mentioned earlier NO phones any where
to be connected Directly from the wall outlet. if you use BB service.
In each room use additional ADSL splitters.
Purpose is to block DATA signals ( higher freq's) from entering telephone line.
The other Port marked Modem actually is a DIRECT connection to BSNL Phone junction !

Your line have problem. Disconnection happen because of noise. First you have to think why you are getting the noise sound because your line have problem. Line have problem not mean that the line in your home or home to outside Telephone Box. The line problem also can be from outside Telephone box to Exchange. If the user line is good then using telephone will not change the SNR value. You have to contact with DE or SDE to solve your problem.

No, my connection setup is OK, issue's with noise, a lot of crackling noise, I borrowed my neighbor's ADSL splitter and used it, and it didn't solve anything so no issues with the splitter, that's one issue checked. I suspect the noise to be coming from BSNL posts cause I never changed my concealed wiring and never gave any trouble before, now the problem becomes very prominent when I pick up the phone, when I pick up the phone sometmes this happens:

There is lots of noise in the line lately, sometimes it becomes unbearable, sometimes it fades away, now the weird thing is even when the noise goes away the line may get disconnected, and it can stay connected even when there's a lot of noise.

Now, I have a few questions:

1. Can a faulty telephone splitter(not adsl but normal phone splitter) cause this, although its connected only after the main adsl splitter(to the phone line that comes off the adsl splitter)?

2.Can a faulty phone cause this(some sorts of short-circuit)?
Once my friend was having this issue and the BSNL technician told him to change the phone.

Today, I'm going to the local BSNL office to lodge a complaint, now its just a matter of time before the technician comes along.

That's what I think, my home wiring has never given me any issues, so far. I suspect the telephone box nearby, it looks horrible, lots of wires all jumbled up, its not even covered or anything, and since using the phone(just picking it up) causes the SNR values to plummet.

Hey buddy, I've also been using the same modem for the last 4.5 yrs now. I can't deny that there've been various issues at some point or the other, but overall it's quite decent. The points suggested by the others, especially essbebe, are really valid, as most of the time the problem is with the wiring.

In my case, I had the same issue of frequent disconnections. After having inspected and corrected the wiring problems, I also opened up the modem and cleaned all the dust and grime with rubbing alcohol, and a lint-free cloth. The rationale being that this is a really dusty area -- I was surprised to find the entire interiors blocked with dust.

The disconnection problems are now gone, and I make it a point to repeat the "internal cleansing" every few months.
Therefore, after correcting the wiring issue, you may wanna try this out, of course at your own risk

Hope this helps...good luck

I know that this modem's pretty decent, but apparently it has very low tolerance to noise, even the slightest crackle in the line makes the dsl go out of sync, the BSNL technician didn't come today(big surprise), so I'll just have to nag them a bit more, I checked my wiring as best as I can, seems there are no issues at my end.

BTW- can you post your modem status log for me, mine looks like this:

As you can see for both SNR and Attenuation, the US and DS are totally different as I've marked out. Does your's look same?

Hi dude,

I do agree that the modem has low tolerance to noise.

as you can see, my line stats are way less favourable, as compared to yours... but I do get consistent connections for hours and hours (more than 10 hours last time I checked)...

I also have wifi enabled all the time.

Yeah, that clears my doubt with the US and DS margins being different(its same with yours), and apparently I've seen that even with stats as low as yours the net stays connected as long as the phone is not picked up or somebody calls up, if I pick up the phone or someone calls me the dsl goes out of sync, so my primary suspects are the Phone and the Modem, there's something else though, it seems you have ADSL2+ enabled, that might have something to do with it, as you see I have GDMT enabled(it has been enabled from the start) so this modem might have issues with GDMT and noise.

So basically I've got two issues:

1.DSL goes out of sync randomly, this issue's a bit less prevailing now.

2.DSL goes out of sync as soon as something is done with the phone(not necessarily picking it up, even an incoming call disconnects the dsl)

Yesterday called up the BSNL office, they are still sending the technician(apparently he is coming down from alaska and will reach me in a year ), the SDE said something about checking my line parameters today, I just wish they would do that soon enough.

you can access it !

right incoming say white wire .connect red.
or
2.
The rj11 you connect to this BSNL phone junction.

tkin your line have the problem. I dont say that the line in your home. The line of your out side telephone box to your exchange also cause this type of problem. Your problem will be solve when your line get repair

Well, I'll try picking apart the port a bit later, right now I'm waiting for the BSNL technician to show up, I tried switching the wires in the phone splitter and evidently I screwed up and lost dial tone and I switched it back the way it was, however I'll try calling the local electrician(who did the wiring for the entire apartment) and have him double check the concealed lines(specially the junctions), the wiring is so complex(due to concealing) that last time I called the BSNL technician he lost his way finding the correct wire.

The problem is not so severe as it was before, now I get occasional disconnections, like 1 out of every 5 phone use, so this further leads me to believe that the issue is actually with the BSNL post rather than my wiring(I actually get my wiring checked by the electrician every year).

Yeah, I'm thinking the same, now its just some time before the BSNL technician shows up, I've been calling them everyday and damn, the JTO who is in charge of the Broadband section is a complete idiot, he is absolutely an illiterate, knows nothing about SNR or attenuation, he asked me "Is your phone OK?" I said yes, then he said "Your broadband should be fine too," apparently he has the idea if theres no noise in the lines then its ok, he doesn't know that if the noise is high frequency it should be cut off by the phone(or splitter) itself, so I told him about SNR and he was looking at me as if someone told him that the sun rises in the west

Its unfortunate that Airtel has no nodes in my area.

BTW- if you take airtel broadband do you need to take phone connection as well?

like 1 out of every 5 phone use, so this further leads me
Presume only a single phone is in use.

Yes, you have to take their phone connection too. If possible tell your JTO that you notice lots of noise in your phone when you are talking over the phone.

Yes, there are two phones in total, one is in my room and I tested using that only, i called my residence phone from my mobile and tested multiple times.

That's a bummer, so BSNL is my only choice for now, yesterday was just terrible, the dsl out of sync issue happened for the entire evening and continued till the next morning, got really mad and phoned the JTO today, apparently it worked, he checked my line from the office(line parameters) and presumably got something repaired(but still didn't send the technician), the line is in good condition right now, I've got my fingers crossed.

The noise in the phone line is completely gone.

The Modem Status remains same:

If the phone rings, the SNR parameters for a second drops to:

But the dsl stays in sync. And a bit later the DS SNR jumps back to 29.

If I start a conversation in the phone the line stays in sync and the DS SNR hovers between 26 and 29.

So its fixed and the most weird thing is the issue was neither at my end or at the local BSNL junction box as speculated by us but rather at the local BSNL office(at their server racks or something like that), a small tweak there and its apparently fixed, I'll still need to observe my lines for atleast a week before I can confirm anything but its ok for now.

A Big thanks too all you guys, essbebe, Indranil and dnjkane for helping me out here, I'll give feedback later about line condition and about the sync issue but for now I'm all set.

BTW- The JTO also told me something else, I don't know if you guys have heard about this but he said the the older switches(he said P2 switches) have low tolerance to noise and goes out of sync easily, these are the switches that assign the 59.93.xx.xx range of ips to us, but the new switches called MP switches work with a lot of noise properly(the ip range 100.xx or something), he said BSNL will switch all users in our area to MP switches soon and the issues will go away. Hope so.

Speedtest.net results came out as 1.78Mbps down and 81ms ping(I can't post images yet).
Earlier I was lucky to get 1Mbps speed and the ping was like 200+ on this server, half the time the test failed in the middle.

My issue's all FIXED for NOW.
