Rep Power: 1 | Hi guys, I am using Dataone BB, Home Plan 1350 UL (512kps). I got my connection jus 5 days ago. I live Ongole, Andhra pradesh. I moved here last month from chennai. Ever since i got my net connection i am experiencing the Frequent disconnection problem. I searched thru indiabroadband.net and found that many others have also reported the same problem. Still my problem is unsolved. I am using ITI DNA-A211-I modem. Here is my problem. I use the net in dialer mode. So, when am using the net (browsing or downloading), suddenly the dialog comes up in the screen saying that "Connection to Dataone lost. Reconnection pending", with a 60sec timer on the Redial button (screen shot "net problem.jpg"). But, even if i press redial within say 3 secs or so, i am perfectly able to connect to internet, and that if i start downloading any file, am able to download it with full speed. Am experiencing this problem like once in an hour or so. Sometimes the interval between 2 disconnections is 10 mins(tho not many times). Sometimes it is 1.5 hrs. I have attached the screen shot of "modem statistics" with the SNRs, attentuation, etc. I think they are quite the normal value, or i may be wrong. But first, here is wat i have already done. I have complained to the BSNL guys. The linesman came and inspected, then went to the exchange and they checked the line. At first they said, the line is faultless. Then i went to the exchange and asked them to check again. Then the SE in the exchange checked the line in front of me and said there is a little prob in your line and it will be rectified. Then the linesman came to my house and changed the rosette box (white box, where the line from the street post to your house ends in a socket), but did nothing to the line. Still the problem exists. Everythin is new- the splitter, the modem, etc. Additional information. I DONT use more than one phone. Also the phone is not connected before the splitter. The line from post is connected to the splitter. From spillter, it is to modem and phone. I have already formatted the system TWICE to be sure of any virus attacks. Checked the wire inside the house. No twists and bends!! I use the connection in PPPOE mode. Have attached the screen shot of the DSL settings and the WAN settings. I read in some other post, advising to change to only G.Dmt mode and disabling the ADSL2 and ADSL2+. Did that, but the problem remains the same. Here is my view point to the prob: Since, i am able to reconnect to the internet within 2 secs of the disconnection, i really cant find out if there is any fault in the line. I mean, so far, i have never seen the DSL link unstable or blink even shortly after a disconnection. Also i cant see if the DSL link goes off or blinks exactly at the point of disconnection, since it happens for jus a second. Also, am immediately able to download file with maximum speed after reconnecting. Additionally u can c the attached screenshot of the utorrent speed graph. Hope i am clear. Please help me guys. Am still believing that there is no prob in my computer and there might be some prob in the line. But BSNL guys keep saying the line is OK and there may be some prob in my computer.

Rep Power: 1 | Ya, i will try that. In fact i have already said that to the technical engineer. Also i asked him to check my modem for atleast 3-4 hrs continuously, coz previously when they checked in the exchange, they just connected my modem to their computer and waited for some 3-4 mins (no disconnections), and they said no prob with the modem. The prob with BSNL is that, most of the guys just dont listen to any suggestion that we say, and they also lack deeper technical expertise. |

Rep Power: 2 | You just remove the splitter from the line and put ur line directly in to modem. then check whether it is still disconnected or not |

Rep Power: 9 | are there any joints from the DP box to ur rosette box. also check if there are any noise when u pick up the phone. if yes, u may need to clean the joints of carbon deposits |

Rep Power: 12 | PROBLEM ITI DNA-A211-I modem INTERMITTENT CONNECTION/S @tnsantosh 1.Your attenuation D/L is quite high. 38.5db. How far , are you from the exchange ? If it is a old telephone line check contacts for rusting/oxidization/black color etc. 2. Try again : disable ADSL2 adsl2 + and check D/L snr and attn. 3.Change DNS to 208.67.220.220 and 208.67.222.222 in modem , as well as in TCP IP properties. 4. Connecting modem directly to the phone jack. see this diagram. It is connected direct with the splitter in circuit !!!!! ! http://i34.tinypic.com/s4c0me.jpg the splitter prevents data signal getting into your phone. and reducing the Data signal. If it is faulty, you can hear a "Hiss' in incoming calls. 5. Check this in the modem. In Management there could be a menu item called client tr_069. 192.168.1.1/main.html. If enabled disable it. 6. If using IE in Internet options "connections," select "Never Dial a connection " pARA TWO : The modem is having same board as Beetel220BX1. Latest FW available. http://www.indiabroadband.net/attach...-bsnl201be.jpg beetel220BX http://img149.imageshack.us/img149/7118/67318793or0.jpg feedback please.

Rep Power: 1 | Thanks essebe!!! sorry for the late reply!!! BSNL server was down all day here in AP. here is wat i did after ur advice. I deselected the ADSL2 & ADSL2+ from the DSL settings as u said and operated with only G.Dmt. And yes, i too noticed the fall in attenuation values. Also to note, the output power for upstream when ADSL2 is selected is always 0, as u can see in the modem statistics screen shot. Anway, even operatin in G.Dmt mode, the disconnectins still happen. Then i removed the phone line from the splitter and operated only the modem. Still disconnections happen. Then i removed the spiltter and connected the modem directly to the wall socket and checking for any disconnections (i cudn't monitor the progress since the server was down all day long and jus got back the connection). Will monitor the activity tonight with this setting, if it helps any. Anyway, to ur question, the line to my house is new, coz, i got the phone connection some 10 days back. And to the best of my knowledge, so far i haven't heard any considerable noise in my phone nor any disconnections when i am talkin in phone. By the way, i have changed the protocol on the WAN setting from PPPOE to Brigde (last night), since i connect using a dialer and also no need to share the net connection as i am using jus one pc here. But, that too didn't prevent the disconnections. And to ur advice abt changing the DNS servers, i haven't done that yet. Coz, i wanna try evry solution step by step. So, i will c if the connection of the modem directly to the wall socket has any disconnections or not. If it has, then i will change the DNS servers as u said. One question!! Since now i am in the Brige protocol, the provision for DNS assigning is not present under adanced settings in the modem. I presume it is set to get DNS servers automatically. If i switch back back to PPPOE mode, the DNS option is there under advanced settings. But, when "Automatic Assigned DNS" is enabled, the values for both the primary and seconday DNS is 192.168.1.1 in the "Device info" page of the modem. Is this normal? And yes, the TR-069 client is enabled on my modem. I have no idea abt that. Can someone explain what it is, so that it'll be helpful in understanding modem configs. And i will check disabling them in the next try. So, as of now, i am in Bridge mode, both ADSL2 and ADSL2+ enabled, and the modem dirrectly connected to the wall socket. Will update the result. |

| Amor vincit omnia | In the network connections, right click the newly created connection (the one which helps u get connected to internet). Under the General tab, select TCP/IP properties. U will be able to enter the custom DNS server IPs in there. This is how DNS is configured in bridged mode. |

Rep Power: 1 | All right!!! even connecting modem directly to the rosette box didn't solve my problem. So, i have changed the DNS servers from automatically obtaining to the values 208.67.220.220 208.67.222.222 in the TCP/IP properties of my Dataone dialer connection. Here is one curious question!!! In my networks connection window in the control panel, i have 2 sections 1. Broadband : where i have Dataone One PPPOE dialer. 2. LAN or high speed internet: like everyone i also have "local area connection" & "1394 connection" The TCP/IP properties of the "local area connection" are assigned to obtain automatically ( both IP as well as DNS ). Does this need to be assigned to use any prefered values or can be just left to obtain automatic values. Anyway i have jus assigned the ip address and gateway as 192.168.1.2 and 192.168.1.1 respectively and have left the DNS values blank. Coz, as i said, i have changed the DNS values in the TCP/IP properties of my Dataone Dialer to use the preferred ones. And i am prefectly able to connect to the net. Here is the extract from ipconfig /all results: Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : Realtek RTL8139/810x Family Fast Eth ernet NIC Physical Address. . . . . . . . . : 00-11-D8-9E-B8-00 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : 192.168.1.2 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1 PPP adapter Dataone: Connection-specific DNS Suffix . : Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface Physical Address. . . . . . . . . : 00-53-45-00-00-00 Dhcp Enabled. . . . . . . . . . . : No IP Address. . . . . . . . . . . . : *************(intentional) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 117.200.0.154 DNS Servers . . . . . . . . . . . : 208.67.220.220 208.67.222.222 NetBIOS over Tcpip. . . . . . . . : Disabled |

| Amor vincit omnia | U have done it correctly. There is no extra modifications needed in the configurations of LAN card properties and Dataone pppoe dialer. Let the DNS entries of LAN card remain blank. But like u mentioned make sure the default gateway and ip address are configured. |

Rep Power: 1 | Unsuccessful again!!! Here is the thing. As i said in my very first post, i can re connect to the internet succesfully after any disconnection within 3 secs. And because of that i really cannot see any unstability in the DSL link even if there is any. Now, i just tried unplugging the phone line (RJ11) from the back of my modem, when i am using the internet. The DSL link starts blnking obviously. But the pop-up saying "connection to datone lost" does not come up immediately. In fact, the dialog comes only after i plug back the phone line into the modem, and after the modem boots itself and DSL link becomes solid. Strange!!! (I guess thats part of Windows.) So, my question is, if at all there is any problem in line or splitter, or the RJ11 cables inside the house, what is the behaviour of the DSL link in general? Do they blink at all, or they remain solid? please answer this question guys!! |

| Amor vincit omnia | A slight variation in the signal strength from the exchange will cause the link light to flutter. I have even come across DSL modems showing unstable link due to poor voltage supply requirements. U can also try connection the modem AC adapter to the UPS (which supports voltage conditioning). |
