Saw this over the weekend while driving. Had a connection but the browser would not connect, no idea if I had previously lost the cell signal. I then cycled flight mode, started browsing, lost signal, regained signal, browser would not connect.
To recreate this I blocked the cell signal momentarily, regained it, and the browser does not think its connected, so I assume this happens 100% of the time that we lose signal. $ nmcli d DEVICE TYPE STATE CONNECTION ril_0 gsm disconnected -- wlan0 wifi disconnected -- but ril_0 is connected acc to the indicator [ /ril_0 ] [ /ril_0/context1 ] IPv6.Settings = { } Settings = { } Password = AccessPointName = nxtgenphone Name = ATT Nextgenphone AuthenticationMethod = chap Active = 0 Username = Type = internet MessageCenter = http://mmsc.mobile.att.net Protocol = ip Preferred = 0 MessageProxy = proxy.mobile.att.net:80 [ /ril_0/context2 ] IPv6.Settings = { } Settings = { } Password = AccessPointName = phone Name = ATT Phone AuthenticationMethod = chap Active = 0 Username = Type = internet MessageCenter = http://mmsc.mobile.att.net Protocol = ip Preferred = 1 MessageProxy = proxy.mobile.att.net:80 [ /ril_0/context3 ] IPv6.Settings = { } Settings = { } Password = AccessPointName = wap.cingular Name = ATT WAP AuthenticationMethod = chap Active = 0 Username = Type = internet MessageCenter = http://mmsc.cingular.com/ Protocol = ip Preferred = 0 MessageProxy = wireless.cingular.com $ /usr/share/ofono/scripts/list-modems [ /ril_1 ] Online = 1 Features = gprs ussd net sms rat sim Powered = 1 Serial = 354142060380047 Interfaces = org.ofono.ConnectionManager org.ofono.Phonebook org.ofono.CallBarring org.ofono.CallForwarding org.ofono.CallSettings org.ofono.SupplementaryServices org.ofono.NetworkRegistration org.ofono.PushNotification org.ofono.MessageManager org.ofono.MessageWaiting org.ofono.RadioSettings org.ofono.SimManager org.ofono.MtkSettings org.ofono.CallVolume org.ofono.VoiceCallManager org.ofono.NetworkTime Type = hardware Model = Fake Modem Model Revision = MOLY.WR8.W1315.MD.WG.MP.V37.P5, 2014/05/15 11:49 Lockdown = 0 Emergency = 0 Manufacturer = Fake Manufacturer [ org.ofono.ConnectionManager ] Bearer = none Powered = 0 Attached = 0 RoamingAllowed = 0 [ org.ofono.Phonebook ] [ org.ofono.CallBarring ] ** Also affects: canonical-devices-system-image Importance: Undecided Status: New ** Changed in: canonical-devices-system-image Importance: Undecided => Critical ** Changed in: canonical-devices-system-image Status: New => Confirmed ** Changed in: canonical-devices-system-image Milestone: None => 12 ** Changed in: canonical-devices-system-image Assignee: (unassigned) => John McAleely (john.mcaleely) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1565717 Title: No connection after returning from area without coverage Status in Canonical System Image: Confirmed Status in network-manager package in Ubuntu: Confirmed Bug description: After moving in an out of my own "faraday cage" an ubuntu phone, NM got into an state where *both* WiFi and cellular data were disconnected and NM was not able to recover.
