Thread: strange connection problem with siemens c2110!

hi all,
i have BSNL broadband connection with 750 unlimited plan.and i am using a Siemens c2110 type-1 DSL modem

1) my problem is whenever i turned on the modem,all lights excpt the data is on.

To connect internet ,i have to manually connects through "open network connection > internet gateway> coonects" .

2) once connection s established ,the second problem arises...frequent disconnection.........sometime connection last hours and Most time only few minutes

i am using Acer 5050 lap with genuine windows xp pro SP3,1 GB RAM

1. I request you to refer this link for
instructions for settings for the modem /
C2110 ADSL MODEM (Type-A) MENU

2. It appears you are on "Dialer'" mode. Kindly confirm.

3.Please give ipconfig/all data for users/members
to advise you further in the matter.

Start RUN type cmd type ipconfig/all

4. May I suggest, changing the DNS in TCP/IP properties
to Opendns 208.67.220.220 and 208.67.222.222 ?

5. Presume you have connected all PHONES after the
ADSL splitter.

DATA led off means you are in dialer mode & not in pppoe mode.go to overview & in there see that both of your SNR values are above 10 & Attn values are below 35.

better switch to ppoe mode.. link given in post 2 . also ensure that all telephones are connected after splitter.. post your SNR value from http://192.168.1.1 (under STATUS_

@essbebe
2- i checked the config and connection s always on! dat means i m not in dialer mode

3-here is ipconfig data

check attacthed pic

@whitestar_999

the config page shows
- PPPoE LlcBridged ON

Downstream Data Rate 2041200
Upstream Data Rate 861700
SNR (Downstream) 18.0 dB
SNR (Upstream) 7.5 dB

@superprash2003
when i tried to manually connects through "open network connection > internet gateway> coonects",it works fine...bt everytime i have to do this manually + frequant diconnection prob

your SNR upstream value is very low.it must be above 10.also your attn downstream & upstream values are very high & should be much lower unless you are 4-5 kms or even farther away from exchange.check that connected standard is G.dmt & not ADSL2/2+.i think you need to get your line checked by BSNL.also in your connection setting click on edit(red pencil icon) in front of connection named something like 0_35_ & click on next till you reach a screen where there should be some option like"dial on demand" & "always on".make sure "always on" is selected & not the other one.if not then select this option & click on apply.restart modem & you are done.do not change any other setting while clicking on "next" to get to next screen while editing connection.

i have deleted the existing connection ppoe-35 and added with same config bt i am confused with wan ip...which ip shud i use? or is it obtain automatic...

i just added with "obtain wan ip auto" and now i dont get connecion...when i troubleshooted,i got info dat sayin "connection to primary dns fail"

can anyone help me with resetting and setting up new config?

while manually configuring c2110 in bridge mode, leave the wan ip page unfilled.
the end result will look like this.
