Thread: ADSL Link Problem

I use utstarcom modem, and recently i've started getting adsl link problem. The adsl light is not stable, it is on for a few minutes and then goes off and this repeats in a cycle. I checked the SNR which is 12 - 13 dB and Line Attenuation is 28.5 - 16 dB. Is this normal? I called BSNL helpline, they dont have an answer. Should I insist on changing the line? What is the cost? I live in Pune.

(1)Try in DSL menu GDMT uncheck box ADSl2 +
Recheck snr/attn.
(2)
IN DNS use google 8.8.8.8 and opensdns 208.67.220.220
Recheck snr ATTN. stable connection.
(3)
Mention modem/model/make/number
(4)
If on "Dialer" mode uncheck "bridged" and select
PPP/PPPoE mode .
feedback item wise.

tried both of these. snr/ attn changed to 12 - 14 in both cases.

3) UT-300R2U connected by LAN no wifi available.

(4)
If on "Dialer" mode uncheck "bridged" and select
PPP/PPPoE mode .

did that but then net does not connect. am using bridge mode only. even when i change to PPPoE LLC net does not connect. please specify exactly what values i should enter for " username, password, connection type, mru, authentication, obtain DNS automatically,default route, nat and igmp"

1. Check the splitter.

2. Make sure all connections come after splitter. Check this diagram.



3. What error code do you get while disconnection ? For PPPoE mode, try this link

UT-300R2U ADSL MODEM MULTIUSER CONFIGURATION

4. Get your line checked by the line man. Ask him to remove joints and non insulated parts.

5. Check the adapter of modem.

6. If possible, get a new adapter and modem from your friend or BSNL and check whether it solves the issue.

tried all the things u've mentioned. no success. lineman already changed the cable. which adapter do mean by modem adapter?

Power adapter of modem. Connect the line directly to modem (bypassing splitter) and check if you are getting disconnection.

It can be a modem fault, try another modem at your place and check.

3) UT-300R2U connected by LAN no wifi available.

If on "Dialer" mode uncheck "bridged"
PPP/PPPoE mode .

Check my signature link wa 3002_g4 and all setting from Chennai link except WIFI
Chennai Telephones- Changing password in DataOne Pre-configured modem
Enter userId without @ bsnl.in

@essbebe: i meant it is not a wifi modem, it is a normal modem with a ethernet port and usb port. I have a desktop and use the ethernet port for connection. But I dont understand how the settings can affect my adsl link? I have been using the internet connection on same settings for the past 2 years at least.

@meetdilip: I will try and get a new modem from a friend and check out what happens. The splitter is not the problem as even direct connection without the splitter am facing the same problem.

Did you check the Chennai BSNL website
for screen shots for WA3002_g4Always on" PPP/PPPoE mode ( uncheck "bridged"in wan page.
(same as Ut300R2U usb/lan only modem )

I checked the site. My main problem is that when I change the setting from bridged mode to pppoe mode, i cannot connect to the internet, the dialer stalls on "connecting via wan miniport" and there is an error that the remote computer did not respond. But when I change to bridge mode, it connects with no problem. And still the adsl link problem is persistent. None of this has solved that.
Also thanks alot essbebe n meetdilip for your help.

No need to dial if you are in PPPoE. Just switch ON the modem and you will be able to connect to net.

Edit and delete double post ( same matter )
In Network settings Disable the dialer or delete it ( when modem set in PPP/PPPoE mode )

Ok. Did that but still problem of adsl link persists. I would also like to know the difference that it owuld make if I connect in bridge mode and pppoe mode.

PPPoE mode :

1. ID and password entered in modem itself.

2. Best set up for using more than one machine.

3. Supposed to be more secure than Bridge/dialer mode.

4. Can surf net by just switching ON the modem.

Bridge mode :

1. All ports are open.

2. ID and password is stored in dialer. You need to click " connect " to get connected to the system.

3. One machine should be used as server to share connection.

Thanks for the info. But my main problem of adsl link failure is still as it is even after changing all the things suggested in the posts above. How can I solve that problem?? please help.

This case can only be solve by BSNL. The problem either from the DSLAM or from the cable. You canot do anything from your side.

I would also to know whether having a cordless receiving unit near the modem has any effect on the adsl link? I use a panasonic cordless phone which worls on 2.4 Ghz.

Possible. Switch off the base and recheck.
From Post No 1.UT300R2U

I checked the SNR which is 12 - 13 dB and Line Attenuation is 28.5 - 16 dB.

If possible from Modem menu pages
report ( with phone on and Off.)
In DSL incheck adsl2+ and enable bitswap.
In Management cheeck menu item Client TR_069
,and disable if enabled.
Mod mode selected snr attn line rate data.

No luck with the cordless switched off..

Test the modem at a friend's internet connection.
If same problem see Post No.18 and contact JTO BB in your exchange.
If on Dialer mode try PPP/PPPoE or visa versa.

ok. will try new modem and check. The bsnl lineman has agreed to change the whole line. Lets hope it solves the problem, but too bad there are holidays now..

Check under Management:
Client TR_069 is it enabled" ?. disable it

Before changing whole line (cable pair) just suggest to lineman to check dsl(link) status on exchange MDF, If there link is ok problem may on line, if not problem on DSLAM PORT on exchange, then suggest to change your PORT.
