Seems like network-manager 1.0.4-0ubuntu5.1 fixed this bug. That makes this like duplicate of LP: #1512749

It seems to reproduce often but not always which might point to some kind of race condition handled badly. Basic setup: * Huawei USB 3G modem * Network manager set to auto connect with saved pin * Laptop which has very few suspend-resume issues so I use suspending all the time I noticed the bug that modem led and network manager indicated that there was a connection. But connection didn't seems to work. My initial workaround in hurry was just to pull the modem from laptop and restart both modem manager and network manager. (they don't like modem unplugging or individual restarts but those are long standing separated bugs that I haven't cared to report) After restarting connection comes up working. I decided to investigate what is broken after resume and I could narrow issue to be that default route is missing from routing table. That resulted to very simple fix where I can simple manually add the missing default route. Broken table after suspend: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface link-local * 255.255.0.0 U 1000 0 0 ppp0 rantapallo * 255.255.255.255 UH 750 0 0 ppp0 Working table before suspend: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default * 0.0.0.0 U 750 0 0 ppp0 link-local * 255.255.0.0 U 1000 0 0 ppp0 rantapallo * 255.255.255.255 UH 750 0 0 ppp0 Command to add the missing route manually: sudo route add default netmask 0.0.0.0 metric 750 dev ppp0 That is at least so far only missing part of connection setup after suspend. I will report a separate bug if I see a different error causing similar reconnecting failure after suspend-resume. apport should include syslog with detailed log from suspend-resume and service restarts to get correct route tables.
