Hi. I just joined this forum, hoping to find some help. I have been using LG RD5130 for almost a year now on my Toshiba laptop using an original LG-make USB cable integrated with Serial-USB Converter model LG-USBC1000-X with no major problems. Recently I had a sudden problem when I could no longer connect to the internet. I could not even reinstall as the modem would not get detected. I contacted R-Connect at Reliance helpline to be told to replace the LG cable with a plain USB cable without a Serial-USB converter. LG don't have a plain cable and they only sell the one with the converter and that too at Rs 1400 approx. I informed this to R-Connect at Reliance helpline who then advised me to buy a local cable from the market. They said they have been facing problems using converter cables and recommend only plain cables. With great difficulty I found a plain USB cable from the local market and installed the drivers using the software for LG RD-5130 USB that I downloaded from Reliance website. Immediately after installation and system restart, the dialer came up normally and I plugged in the username (my phone number) and the password (again my phone number). I could then connect with the internet superbly. Here comes my problem now. If I switch off the Rconnect dialer and then try to reconnect to internet, the status window shows: CONNECTION TO THE DEVICE... and then remains there. After a moment, it would come up with an error: "0680: There is no dial tone." Re-installing did not help, not even using help of Reliance people. Rconnect department of Reliance says this is a computer configuration problem and has nothing to do with the installation or the driver. After thorough checking, I found following issues: 1. Control Panel - Network Connections window: Initially, device name shows LGE CDMA USB Modem. This is correct. I am able to connect to internet. 2. After disconnecting internet, the device name LGE CDMA USB Modem changes to Toshiba Software Modem AMR which is the main laptop modem. 3. Upon trying to reconnect it cannot do so and only comes up with error 680. This means the LG CDMA modem is longer available for connection and instead the dialer detects only Toshiba Software Modem AMR. Obviously it would not connect because the phone number still shows as #777. 4. I then checked the Phone and Modem Options in Control panel. LG CDMA modem is very much present and I can even do a successful Query Modem from the Diagnostics window. But for some reason the modem name disappears from the Network Connections window. 5. If I now disable the Toshiba Software Modem AMR, I am again able to revert to the LG CDMA modem and it works correctly again. But then that is not correct because (a) I use the Toshiba modem for my normal office work and ( the other connections that I have on the laptop should be using Toshiba Software Modem AMR and not LG CDMA. It is unfortunate that so many months the two modems co-existed and now this problem starts. Any help on how to sort out the problem? Sumit

I will try this. But first Yunus could you or someone tell me why the plain USB cable that I currently have WILL NOT WORK once disconnected?

Hi. I called RConnect department and those fellows are in some sort of dream. The guy tells me that he has never heard of a serial-usb converter cable of LG and this is the first time he hearing a problem on the LG RD 5130. He also says that the standard cable is USB and Reliance would not support for Serial-USB converter cable of LG. What sort of **** is this?

I think the problem is with the com port disappearing. Any idea how to solve this?

It is very difficult getting a good usb cable from the local market in Delhi. Do you know any recommended name?

One more observation. You would have noticed from the pictures that when I disabled the laptop modem from the device manager the lg cdma modem immediately got activated. In fact every time I am responding to this forum I am having to do that. Are you sure the cable is faulty or is there some setting that needs to be corrected on the system? Of course I agree that the observations are same on two computers!! Quite perplexing!!

Here are some messages: at OK atdt NO CARRIER atdt #777 CONNECT ath OK atdt NO CARRIER atdt #777 CONNECT atdt #333 NO CARRIER at OK at&f OK at&f1 ERROR atdt #777 CONNECT at&f OK atdt#777 CONNECT at d NO CARRIER

I looks to be a case of COM3 (the virtual port for LG CDMA) disappearing after disconnecing. Look at the pictures here attached. Snapshots.zip

The cable I have is a new one bought from the local market and is a normal usb cable without serial-to-usb converter. The old cable I had was an usb cable with serial-to-usb converter that I bought from LG. That cable is now finished and I have thrown it. I can't buy a serial cable because I don't have a serial port on my laptop.

So is it clear that the usb cable will continue to have problems?

Sorry I didn't make it clear but the old cable is already defective. The modem would not be detected at all which why all this fuss. Do you think I need to buy the new USB-Serial cable (worth Rs 1400) again and discard the USB cable?

Hi. I am repeating something that I already posted this morning on the RConnect Forum, hoping to find some help. Not really interesting help came in though! I have been using an LG RD5130 for almost a year now on my Toshiba laptop using an original LG-make USB cable integrated with Serial-USB Converter model LG-USBC1000-X with no major problems. Recently I had a sudden problem when I could no longer connect to the internet. I could not even reinstall as the modem would not get detected. I guessed the cable was getting bad. I contacted R-Connect at Reliance helpline to be told to replace the LG cable with a plain USB cable without a Serial-USB converter. LG don't have a plain cable and they only sell the one with the converter and that too at Rs 1400 approx. I informed this to R-Connect at Reliance helpline who then advised me to buy a local cable from the market. They said they have been facing problems using converter cables and recommend only plain cables. With great difficulty I found a plain USB cable from the local market. The cable I am using is for LSP 350T LG phone because you don't get direct usb cable for RD 5130. I installed the drivers using the software for LG RD-5130 USB that I downloaded from Reliance website. Immediately after installation and system restart, the dialer came up normally and I plugged in the username (my phone number) and the password (again my phone number). I could then connect with the internet superbly. Even now I am using this connection while on this forum. But... Here comes my problem now. If I switch off the Rconnect dialer and then try to reconnect to internet, the status window shows: CONNECTION TO THE DEVICE... and then remains there. After a moment, it would come up with an error: "0680: There is no dial tone." Re-installing did not help, not even using help of Reliance people. Rconnect department of Reliance says this is a computer configuration problem and has nothing to do with the installation or the driver. They are wrong because I also have a desktop at home and I found the same problem there. After thorough checking, I found following issues: 1. Control Panel - Network Connections window: Initially, device name shows LGE CDMA USB Modem. This is correct. I am able to connect to internet. 2. After disconnecting internet, the device name LGE CDMA USB Modem changes to Toshiba Software Modem AMR which is the main laptop modem. 3. Upon trying to reconnect it cannot do so and only comes up with error 680.

But then that is not correct because (a) I use the Toshiba modem for my normal office work and ( the other connections that I have on the laptop should be using Toshiba Software Modem AMR and not LG CDMA. 6. The internal modem (Toshiba AMR) is on COM 4 and the LG CDMA Mobile is on COM 3. 7. Intermittently I get errors like UNSPECIFIED ERROR or 619 or 680. I restarted the computer but no change. Can't understand what's going on!!!!! It is unfortunate that so many months the two modems co-existed and now this problem starts. Any help on how to sort out the problem?

I did that. But I checked this on another computer and got the same behaviour. The cable I am using is for LSP 350T LG phone because you don't get direct usb cable for RD 5130.

Done that. Laptop is detecting usb cable. Otherwise I wouldn't have been able to connect to internet even first time.

Hi. Is there no one who can help? Hyd Ladka suggested I go to Messenger but I am bad at that.

And now a new problem. After I reinstalling I am now getting 619 error. I restarted the computer but no change. Can't understand what's going on!!!!!

Hi. Thanks. The internal modem (Toshiba AMR) is on COM 4 and the LG CDMA Mobile is on COM 3.
