So a couple more comments... 1. Do we know if NM sees the mobile connection drop, and thus it re- activates the context again, or does the context appear active to NM the whole time and the connection drops and re-establishes itself without action from NM? My guess based upon Oliver's description is that the latter is happening.
2. Android is obviously able to handle devices that configure the routing table ( although I have seen references in the code that rild implementation should *not* do this ). Do we know how Android handles this? 3. How difficult would it be to change the NM policy so that we never have concurrent active mobile and Wi-Fi connections? Our current model is that we leave the mobile connection active when Wi-Fi is activated, and then just switch the default route to Wi-Fi once connected. One final thought along these lines, does this leave us in a situation where an app could have an active network session and continue to use mobile data when Wi-Fi is activated? -- 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/1307981 Title: [touch] randomly messed up routing with recent trusty images Status in “network-manager” package in Ubuntu: Confirmed Bug description: I have no clue when exactly it started (probably before image 290), but since a while i experience random issues where the browser suddenly doesnt find websites anymore ... digging deeper i can see that the routing table is completely messed up having two default routes: root@ubuntu-phablet:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 37.85.159.174 0.0.0.0 UG 0 0 0 rmnet_usb1 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 37.85.159.172 0.0.0.0 255.255.255.252 U 0 0 0 rmnet_usb1 192.168.2.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0 i did not roam or switch networks, this phone was constantly on wlan in the same room. afer a reboot the routing is normal: root@ubuntu-phablet:~# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0 37.84.75.140 0.0.0.0 255.255.255.252 U 13 0 0 rmnet_usb0 192.168.2.0 0.0.0.0 255.255.255.0 U 9 0 0 wlan0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1307981/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
