    Exclamation Bsnl broadband limited connectivity issue

    Dear,
    I have an issue with my bsnl broad band connection..it is showing limited connectivity during night.Almost all days around 10 pm onwards it is like that..then i will try to release,renew my IP,but no use..i tried to restart modem and computer also..
    Im also facing severe connection cuts during normal time..
    When i called bsnl ,they told me "Limited connectivity" is because of my voltage fluctuations...but i had connected my modem to UPS only so how electricity will be an issue..?

    Please help me to solve the issue..F
    From where this issue coming..?To whom i will contact?

    1. Post your SNR and attenuation values.

    2. Try ipconfig/flushdns.

    3. Are you sure that it follow the 10.00 PM pattern ? Which OS do you use ? Try " Repair ". If using Windows 7, post the screen shot of " See full map".

    4. Ping 192.168.1.1 during limited and no connectivity and post the result.

    5. Start > Run > cmd > ipconfig/all, post the screen shot.

    Sorry Mr.Dilip..currently im now in KSA.its my home pc ..im using teamviewer to access the machine..but still now it is limited connectivity..2morrow i will post the SNR rate.Im using Win xp..

    The main thing i want to know about BSNL is:
    Is it a common issue for bsnl this "Frequent disconnection"..
    im facing it too much.. mostly during 7-10 pm..??

    No problem. Take your time

    Let us hope it is a line problem. Can be confirmed only if we see the SNR and attenuation values. You can also check the splitter, power adapter or modem itself. If available at any of your friends', try a replacement and check. But if it is happening during certain period, it is a line issue. In the mean time, you can talk to the SDE and seek help. Call customer care and ask for his no.

    Unhappy [b]iti dna-a211-1 -[/b]

    Dear,
    My modem is ITI DNA-A211-1 -

    2day morning i tried to enter the modem and suddenlyi lost the connection.i got the message limited connectivity.after noon its ok.
    In the evening around 9.50pm same thing happened "Limited connectivity".
    I tried ipconfig \release,renew,flushdns,registerdns...

    During limited connectivity i cant ping to 192.168.1.1 & 127.0.0.1

    One of my friend said to disconnect land phone from the splitter,then it will be ok.But up to 9.50pm it is ok..it didn't disconnected.

    I tried to connect the modem directly to the Power without UPS,but the result same.

    bcoz of disconnection im afraid of entering inside the modem .i will put the SNR rate tomorrow .

    ADSL splitter must be used for connecting ALL telephones.to its PHONE port. ( whether phone is used or not )

    Copy/Paste ipconfig /all data
    Start run type cmd Ok
    new window
    type ipconfig /all
    Delete all tunnel data if shown.

    In advanced setup select DSL uncheck ADSL2 + box

    Also un check /disable k Client_tr069 ( see Under management )

    Save reboot wait for 2 minutes.
    for a stable connection. SNR ATTN values may change.

    If you do this remotely , connection may be lost.
    user in India may have to start modem /system again.



    Para two:
    For " impedance matching" , telephone may be connected.
    If "Hiss" sound is heard in Phone splitter not connected properly.

    Exclamation

    Dear Essbee,
    i will do the suggested things today .
    but when i login to the machine in the morning i noticed that the "Local area connection is now connected" status is always coming in 30 or 40 seconds intervals.also "Network unplugged" message is also coming all of sudden.

    http://www.indiabroadband.net/attach...1&d=1296453410

    In the morning time there is no limited connectivity issue.

    Thanks and Regards,
    Anu

    There is an option in Network Settings page
    (START/NETWORK/LAN)
    see in bottom .
    Un check box
    "Show limited or no connectivity "
    Some prefer to have this option selected.
    What you are seeing is the LAN data
    transfer speed. Not Internet speed.

    2morrow i will post ipconfig

    I have opened few Splitters and studied them having worked for service sections of BSNL formerly.
    the line socket is directly taken to Modem socket. The modem related High Pass filter is inbuilt in the modem itself.
    only a low pass (voice filter) is implemented towards Phone socket.
    Under these situations, the splitter should not be reverse connected ( modem at phone socket).
    otherwise no issues even if one connects the line to modem straight.

    Dear ,
    Im not too much aware of this splitter. i will describe it how it is connected to my modem
    There are three ports in my splitter.
    1.PHONE->To the Telephone
    2.ADSL->To the Modem
    3.LINE<-Connection from the exchange..

    @ night i will remove the
    1.PHONE->To the Telephone
    i wish this will help to increase the voltage of the line....

    By the way can u tell me what is the perfect voltage for my modem..?

    Thanks and Regards

    ITI DNA-A211-1 -


    Enter in DNS menu of modem
    208.67.220.220 and 8.8.8.8
    Computer:
    Also in NETwork/LAN/properties/
    TCP/IP properties
    DNS same values as above.
    Apply Save.

    If break is for short period and then connection is restored,
    some problem at BSNL end probably.

    Check your IP of system ( at home )
    http://whatismyipaddress.com
    Type it here now. to check your router ONLY>

    or you can check entries in my modem NOW
    type it in your browser

    Default Limited Connectivity:

    Hi,

    You must also know the following about ADSL technology which is used in broadband service by BSNL.

    >> It is a best effort technology. This means that the advertised speed rates are possible only if the user is located close by the central office or CO (normally, this is the telephone exchange), else speed decreases and noise increases with increasing distance.

    >> The ADSL signal has limited range. Since the DSL carrier signal is a high frequency signal over a wired channel, there is a definite loss in terms of signal strength and noise increases. Thus the broadband connection is provided only till a specific distance from the CO.

    >> This distance is measured from the wire starting from the CO hub till the end user's location. This is called as Loop Length (LL), and is not the physical distance from CO to user location, but actually the length of wire through which the signal has the travel.

    >> you may try the following to improve the ADSL signal reaching your modem thru the telephone wire:

    - use the provided DSL filter properly. google search for proper filter connection if you are not sure. the device generally provided with the modem is a splitter, which splits the dsl signal and voice signal. so, it is a 2 point extender, with one point filtered. you should have a filter on all instruments except the modem.

    - if filtering does not work, then disconnect all telephone instruments, and any other device connected to all the phone jacks in your house. see if the connection is more stable after this.

    - secondly, try using a shorter wire from phone jack to the modem, preferably less than 6 feet.

    - also, try isolating modem from other electronic devices which generate massive magnetic fields, like TV, Microwave ovens, Cordless phones, amplifiers or unshielded speakers, fan regulators, etc.

    - ideally, you should also get the local telephone exchange to send a person to check if there are any issues with the line such as joints, etc. tell them you will pay some sort of baksheesh if needed.

    Hope that these steps help you to improve the issue.

    Thank you very much for your detailed reply..

    Dear netherwinterknights & Essbee,

    Today technicians from BSNL came to my house and they said that the line from exchange have some issues.
    They checked it in the junction box infront of my House and solved.

    Also the line from Box to Splitter are checked and it's ok..
    The splitter they didnt check..bcoz they dont have splitter.

    I dont know the exact result now..
    I checked with my mom for connection stability...she said it is stable up to 3 hrs in the noon time..

    My my main issue is in the night 9.50-10.10PM..so in the night only i can say anything about these changes.


    Yesterday

    -i removed telephone from the splitter.

    --- Disabled wireless from the modem.

    --- Changed ADSL2+ to ADSL2

    --- Confirmed whether no noice coming from the telephone after 10PM

    --- Changed the location of Speakers which are near to the modem

    --- Checked with nearby houses whether they have any similar issues,they don't have..

    --- Confirmed it is less than 1 km only from my exchange..

    --- My package is 750 cc

    Thanks & Regards

    Thumbs up Thanks to Mr.M.V.S Sharma

    Dears,
    its the time to thank Mr. M.V.S Sharma for his kindness to my "Broad band issues .Actually i was facing 2 issues.

    1.Frequent disconnection..(Suffering from around 2 year)
    2.Limited Connectivity(Suffering from 2-3 weeks)

    Frequent disconnection.
    Mr.Sharma called to my near by Divisional Engineer and DE advised to my local exchange to solve the issue.He himself called to my local exchange several days.Then all of sudden people from BSNL reach my house and checked line and told there is some issues in my line.so they came up with diggers and they put new cable for me from the main box.Also they insulated broken parts and changed the Splitter.My SNR and attenuation rates perfect now.Line man from BSNL came to my house yesterday at 7.AM and gave phone support to reconfigure the modem today @ 10 Pm..Can you believe it .....!!!
    So after long one and a half years my Frequent disconnection issue was solved.Thank you Sir...
    Attachment 8367
    Limited Connectivity
    As frequent disconnection issue solved ,now only the issue of limited connectivity remains.But still BSNL people didn't get a clue about this issue.they suggest it might be becoz of my modem or my PC .May be my PC is affected with some virus.But i dont believe in that, becoz after connection becomes limited connectivity ,i cant use internet from Wireless too....i expect it is the issue from the modem.But up to around 10PM there is no issues with limited connectivity.
    Any way tomorrow they will change the modem and let us see what happens..

    Once again thank you very much sir..i don't know how to express my gratitude for your kind human approach towards my issue...its my extreme pleasure to say without your efforts and hardships ,such a sudden approach from BSNL will not reach towards my issue...you done it for me up to the extreme level.

    Thank you..keep in Touch....


    Dear India Broadband Forum users,
    We cannot see too much broadminded people like him ...Thank you..Sir

    Dears,

    At last my limited connectivity issue almost solved..
    we had done 2 things.

    1.Changed DHCP to Manual IP
    2.Updated windows

    Now there is no limited connectivity coming.
    hats-off to Mr.MVS Sarma...You had made it for me from which i thought quitting BSNL broadband completely....

    In fact the entire greatness goes to the BSNL staff of the Division in Kerala and their team in-charge, Shri Nair, Divisional engineer.

    I am just instrumental to have a chat with my colleague and request.
    As I have been telling, BSNL has good staff teams, and I hope that across the nation, they offer better training to their staff to be able to serve the public better and sustain the good will.

    I know of some places in Kerala and Karnataka (Shemoga for example), where the local municipal administrations have put a B complete ban on road digging after they laid CC Roads. Perhaps this makes the job of
    telecom and other providers very tough.

    wish a happy usage of broadband to our esteemed member ANUCS_IN. I thank essbeebee and many other members who helped me clearing other issues that could be solved by ourselves without any outside help.

    Thank you very much to all forum users who helped me to solve this issue..

    Today i found another reason:

    Limited Connectivity can also occur if LAN card is going to damage.

    Best wishes and Good luck,

    Anu
