@John, not sure if I've noted this down already in the previous comment, but in case I haven't: I usually just tap on the wifi network I'm connected to, to trigger reconnection. That fixes the issue for me (until it stops working again after a few minutes, or less than a minute in some cases I think).

I have captured the logs requested in #25. Note that during the session, the problem with 'network error' occured after a few mins. Unlike in #28, a sleep (power button) cycle did not recover the issue, but I noted that I was connected via ADB, perhaps changing the power behaviour. Therefore toward the end of the log, I used the network indicator pull down to disable and then re-enable wifi. On rejoining the wifi (which it did automatically), the browser could successfully refresh a page. I therefore currently speculate that power cycling the wifi chipset clears this issue. I terminated the log gathering shortly after this event. ** Attachment added: "nm-nl.out" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1580146/+attachment/4692926/+files/nm-nl.out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580146 Title: [touch] Internet connection stops working while WiFi is still connected To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1580146] Re: [touch] Internet connection stops working while WiFi is still connected
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. ' Pressing refresh page, or navigating to other sites, produced the same error. After a sleep cycle and unlock, the 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580146 Title: [touch] Internet connection stops working while WiFi is still connected To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1580146] Re: [touch] Internet connection stops working while WiFi is still connected
@Andrea There are two tests I'd like you to run for me. First, let's verify the baseline by flashing OTA10 ( pre-NM 1.1.93 landing ) on a spare krillin, and then set the WiFi connection to the opposite as earlier suggested, this time setting ipv4.method to ignore. This will validate that IPv6 connections were actually working ( vs. just not causing DNS to fail ), even though the kernels lack support for IPv6 peer addresses ( which NM 1.2x always uses when adding IPv6 addresses, and which in turn always fail ). Second, there are three cases currently that I can see where NM adds IPv6 addresses ( note, there are more possible, but these are the most common when method=auto ): - NM always configures an IPv6 Link Local address with the peer set to the "Any" address ( all zeros or :: ); the code states that a LL address is always added for any method other than "ignore" - a VPN configuration specifies an IPv6 address ( in this case, our VPN always sets the peer with the interface identifier part of the address set to ::1/64 ) - an address is received via RDP ( router discovery protocol ); this is the case that happens when you associate to an AP that supports IPv6 and method=auto As I can't reproduce the last case ( my ISP doesn't support IPv6 yet ), it would be great if you could run NetworkManager in the foreground with an env var specified which triggers netlink debug messages. This will let me see what peer_address is being set when you connect to the work AP. If you want to send me these traces privately, that might be best. Please use a recent rc-proposed image. Here are the steps: 1. From system-settings::wifi, "forget" the access point 2. adb into the phone, and start an interactive sudo session: # sudo -i 3. Stop NM # stop network-manager 4. Run the script command to capture output: # script nm-nl.out 5. Start NetworkManager in the foreground like this: # NLCB=debug /usr/sbin/NetworkManager -n -d --log-level=debug --log- domains=ip6,wifi,vpn 6. From the indicator, connect to the AP 7. Leave the connection up and NM running for 5-10m 8. Kill NM via Ctl-C 9. Exit the script via Ctl-D 10. Grab the script output and send it to me direct, or put on a fileshare Please let me know if you have any questions, or want to discuss before you try any of this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1580146 Title: [touch] Internet connection stops working while WiFi is still connected To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1580146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I noticed at one point dns queries were working again, so I grabbed syslog again. After a short time DNS stopped working. At the beginning of the log DNS was *NOT* working (I know this for sure as I used ping google.com after 16:00:37) while at the end of the log DNS was "likely" to be working (because I pinged google.com and it was working, so I grabbed the log. But I can't know if it stopped working between the moment when I finished pinging google and the moment I grabbed the log) I hope this will help understand what happens between a non-working and working state.
