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
