I tried to reproduce the original error. I flashed my vegetahd fresh (--bootstrap) to ubuntu-touch/rc-proposed /bq-aquaris.en, #366
I walked through the wizard, and added it to the Canonical wifi (Canonical-2.4GHz-g) I performed some random google searches, and confirmed all was well. Over a period of ~10 mins I left the device to idle, powered it on/off with the power button (just sleep of course), and tried to observe the 'network error' reported. Eventually, while on the lock screen, I woke the device to see the wifi password prompt - the device appeared to have forgotten the password for the canonical wifi. As we know, this is a failure mode that can mean other things. I cancelled the dialog, and logged in to the device. Using the indicator menu, I pulled down the network panel. Observing that the system appeared to be on cellular data (2G, note that both SIMS are loaded and registered), I selected the Cannonical-2.4GHz-g wifi network and observed it turned green, and the indicator switched to the wifi signal strength view. Dismissing the indicator Menu, I opened the browser and navigated to a page.The browser displays 'Network Error', 'It appears you are having trouble viewing: http://microsoft.com/. Please check your network settings and try refreshing the page. <Refresh Page>' Pressing refresh page, or navigating to other sites, produced the same error. After a sleep cycle and unlock, the <refresh page> button started working - ie the device healed from whatever state it was in, while I typed this up. -- 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/1580146 Title: [touch] Internet connection stops working while WiFi is still connected Status in Canonical System Image: Incomplete Status in network-manager package in Ubuntu: In Progress Bug description: krillin, rc-proposed, r329 Description: It often happens that the internet connection stops working while the device is still connected to a (working) WiFi AP. The indicator shows that the phone is connected to the AP, here's the ouput of "nmcli d" and "nmcli c" http://pastebin.ubuntu.com/16344985/ Tapping on the AP in the network indicator resets the connection and fixes the issue, which however reappears after a while. Here's also a "grep NetworkManager" from syslog http://pastebin.ubuntu.com/16344990/ How to reproduce: I don't have a recipe, but here's what usually happens on my phone 1) I connect to the office WiFi (Canonical's HQ, BlueFin office) 2) Use browser, perform random google searches to check internet is working 3) After a while (sometimes I put the phone to sleep, sometimes I checked the Updates from system settings a few times), I go back to the browser, and it starts returning "Network Error". NM, as you can see from the logs, says WiFi is "connected" 4) At this point I use Terminal app and discover that "ping 8.8.8.8" is working correctly, "ping google.com" immediately returns "unkown host", i.e. it doesn't seem to be waiting for a timeout, it returns pretty fast.
