@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
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.

In attempting to reproduce #27 again, I have now seen a very similar
sequence, but no passsword prompt for the wifi was made, and the device
has appeared (from indicators) to have been on the wifi throughout.
However, on attempting to access a website, the 'network error' dialog
appeared.

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.

@Tony:
that's great, thanks for all the info :)
I'm on a sprint this week, I will try it first thing when I get back to
the office!

@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
still happening as of r361, krillin, rc-proposed

@Andrea
Can you try adding the following setting to the NetworkManager
connection file for "Canonical-2.4GHz-g" in /etc/NetworkManager/system-
connections:
[ipv6]
method=ignore
"[ipv6]" should already be there, so just add "method=ignore", and
remove any other settings under "ipv6".

I flashed a second Krillin device to rc-proposed r335, the bug was
triggered after just a couple of minutes.
Tony adviced using tcpdump, so I looked for some useful DNS related
tcpdump commands, and that resulted in the log you can find attached
INFO about the device:
It has 1 SIM, which is
not sure, I'd say not, but let's see what Tony thinks

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
Additional info:
it happened, occasionally, that DNS started working again after some time (and
stopped working again shortly after), but I'm not sure what triggered that.

I sent Tony a private pastebin (to avoid leaking sensitive data) with
the logs he previously requested in comment#5, and he was kind enough to
summarize his ongoing investigation in the comment above
additional info:
I rebooted the device and used "powerd-cli active" to prevent it from going to
So from @Andrea's latest pastebin:
- NM shows both modem and wlan0 as connected
- syslog shows one DHCP renewal period
- a do-add-ip4-address error is logged, however the IP address is still
configured ( ip addr show confirms this ); need to investigate whether
the error log message is
