[Bug 268667] Re: CDMA (cellular modem) connection drops often with network-manager

[Bug 268667] Re: CDMA (cellular modem) connection drops often with network-manager
I have this problem as well with a verizon EVDO modem. The problem is that, with my service, I do not get responses back from echo commands. Therefore commenting out either the lcp-echo-failure (or setting it to zero) and/or set the lcp-echo-interval to zero will stop the echo commands and therefore keep the modem from dropping the connection. However, on the PPP tab of the mobile broadband connection editor, the "echo" checkbox is unchecked. To me, this would mean that lcp-echo- failure and interval would be set to zero. I believe checking or unchecking this box has no apparent effect on the /etc/ppp/options file. This (to me) seems like the bug here. -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

FWIW, as suggested by Wayne Towe, editing my /etc/ppp/options so that it has lcp-echo-failure 0 instead of lcp-echo-failure 4 makes my CDMA connection stable as well. -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 268667] Re: CDMA (cellular modem) connection drops often with network-manager
I found a workaround that works for me. I tried turning lcp-echo on and off on Network Manager, but that had no effect. What I finally did that worked was to manually edit the file /etc/ppp/options and comment out the line that reads: lcp-echo-failure 4 Commenting the above line solved the problem for me. -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I can confirm this. I am seeing the same thing with a Verizon Wireless PC5740 card. I can use the Auto CDMA Connection option in Network Manager and I do get connected and am able to use the Internet, but in about 3 to 5 minutes the connection is terminated. I am using Intrepid with all current updates. -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

maybe its a ppp timeout thing? -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 268667] Re: CDMA (cellular modem) connection drops often with network-manager
Not sure what you mean to "verify that your connection is still as stable with chat" but I will restate the problem as follows: I booted up my up-to-date intrepid system, and connected by selecting "Auto CDMA network connection" from the network manager applet menu. The connection worked but it dropped within about two minutes (and NM popped up a "disconnected" notification bubble). Then I went to a shell window and connected by doing "sudo pon verizon" to start ppp by hand, and that worked too, and I remained connected for at least half an hour of using the net. This is not just a one-time thing... it is very repeatable and obvious that connecting using NM doesn't stay connected for long, and connecting with "pon" rarely drops unless I go through a dead spot in coverage. As another data point, I do notice that the connection does seem to be established a little faster with NM than with pon, but I don't have an explanation for that. -- CDMA (cellular modem) connection drops often with network-manager https://bugs.launchpad.net/bugs/268667 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
