Hey, I have an Airtel ADSL 16 MBPS Broadband. It was working pretty fine before.

Nowadays if I restart the modem, it does connect the DSL Light but Internet light doesn't come.

I have to wait for luck or restart few times to have the third light.

Special Note: Third light doesn't blink. It's totally out/off.

What to do? What's wrong?

Modem: TD-W8970 300Mbps Wireless N Gigabit ADSL2+ Modem Router - TP-Link



@igloo @manojrk @Karan @wecaz @waterloo_sunset Please suggest!

Were you able to connect before? Did you change anything in the GUI? Your modem is able to sync but can't authenticate on the network. Possibly wrong username/password or could be the VPI/VCI that is not correct. Could you (if possible) take a screenshot of the WAN part of the config, could tell you better.

@Karan Of course it was working very well before.

I don't think I have changed anything.

I am seeing little bit of frequent disconnection too from last few days. (Since I am facing this problem).

If it is wrong username/password. It wouldn't connect for a second either right. But it does connects randomly (either after restarting again and again until it connects or leave it as it is and pray).

WAN Settings:

Hmm... settings are indeed correct, could be the same intermittent problems you have been facing with your vdsl as well.

@Karan Well is there any chance if LINE is the reason for this?

Because I am listening bit of voice disturbances sometimes when on call + Downstream Max Rate used to be 21xxx but now it's 19xxx-20xxx

If it becomes 21xxx then the SNR would be down.

So basically modem is showing lower SNR to compensate with the SNR right?

What do you suggest?

2 days ago my SNR even went to -2 or -3

Also, Yesterday my SNR was 8.1 and downstream current and max were near 10xxx

Sometimes I find Facebook.com loading really slow.

My current stats:



My old stats before this problem:



If something is done by the backend like changes in profile of 16MBPS. If they happen to reduce max rate, it would have caused to increase SNR right?

But SNR is same but max rate is fallen which do you think can be because of Line only?

I mean the whole culprit is line itself?

@manojrk My Modem is TP-Link isn't it a good modem company? Just curious because it's costly.

I have had rewiring done yesterday direct from sub-pillar to home. (without any joint).

Current Setup:

Blue Box (Sub Pillar) ----> DP -----> Peach Box (to convert Wire into RJ 11 Jackable Port) ---> RJ 11 to Splitter -----> RJ 11 to Modem and RJ 11 to Landline.

I want to add that before 5-6 days ago, it was working very well. But just from last 5-6 days only, I am having this problem.

After rewiring, I have seen a very little improvement in parameters. Not significant.

It's very random again. I am not sure what's the matter.

I have tried using Huawei Modem which came with VDSL, I setup that as ADSL and checked the parameters, it's almost as same as my TP-Link's para only.

What do you say?

Which settings are incorrect?

Can you tell?

Not saying TP-Link's are bad. Yours might be faulty because it seems to lose the sync for unknown reasons. You should try with a spare modem for few days before concluding the line is at fault here.
