Can anyone repro this? Naoki, Johan, flagging you in particular. From the sounds of it, it's best if Johan handles this to start with, though.

Or it's just bug 1154690 ?

Martin, what source are you flashing full images from?

Or related to bug 1167550 ?

I was able to update from [1] to [2] without any issue related to Wi-Fi. I'll check on a couple of networks to make sure of it.

I don't think it's OTA that caused wifi breakage. Wifi is still having issues: bug 1167466 / bug 1164322 / bug 1154690 Can we get a version of the build that Martin is on please?

I did 5 updates from 20150604140701 to 20150608110222 and didn't see wifi break. I suspect Naoki is right in comment 6.

Here is the build ID from the devices that was flashed AOT: BuildID: 20150514170511 Update Channel: cypress

We moved away from using cypress as cypress is outdated. That might explain more of the issue. Could you full flash starting with this build please: https://tools.taskcluster.net/index/artifacts/#gecko.v1.mozilla-central.latest.linux.aries-dogfood/gecko.v1.mozilla-central.latest.linux.aries-dogfood.debug If you're having problems getting the build, please let me know.

I spoke with Martin about this offline, and I believe we've dealt with the issue by moving him over to a more recent, mozilla-central based build. Thus, I'm resolving this. We should still verify it, if possible.

I'll file a new bug if I see this problem resurface. Let's close it.

Removing the qawanted tags since this issue is resolved.
