-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've never used NetworkManager for a 3G connections (used kppp for my previous Palm Treo -- new phone acts like USB ethernet or wireless base station), but I know from experience that this is governed by /etc/ppp/options. As to why it happens, I have to assume that LCP echo is something that modems do that 3G "modems" do not.
Take a look at /etc/ppp/options and at least comment out lcp-echo-failure as I've done: > # If this option is given, pppd will send an LCP echo-request frame to the > # peer every n seconds.

Is there a better solution for Network Manager? I don't know. On 11/22/2010 03:31 PM, hong sheng wrote: > It's 3G connection. It turns to be the chap authentication method > problem.
