Update April 4th 2020 The issue is still not solved in SFOS Rokua. Enabling AP/band steering features in my Fritzbox causes my Xperia X to loose connectivity within a few minutes if I move between access points. In this case, a soft reset (power + volume up) is necessary. To be honest, I don't understand why this serious issue has no "tracked by Jolla" label.

Update: I think I found an avoidable trigger of the firmware crash: It's one of the 802.11 assisted roaming extensions (most likely k or v, but couldn't rule out r yet [and won't investigate further]). Since the crash hasn't happened last week, when I had used a different BSSID, I looked for the differences and disable k+v assisted roaming for the new BSSID on all access points (see https://www.cisco.com/c/en/us/td/docs/wireless/controller/8-1/Enterprise-Mobility-8-1-Design-Guide/Enterprise_Mobility_8-1_Deployment_Guide/Chapter-11.pdf for example, seems to be a good overview).

So far, no crash anymore (about 4 hours medium WiFi usage). Will report if I observe another crash despite disabled 802.11/k/v.

Thanks for your comments, obviously I'm not the only one suffering from that issue. Maybe you can look if your environment also provides assisted roaming extensions and if disabling is possible and helps?

Original question from 2019-05-13:

Hello, the following happens after unpredictable (time+volume wise) WiFi usage on my Xperia X with Hossa using 2.4GHz, WPA2:

Afterwards, anything network related hangs, including D-Bus / systemctld. So I cannot shutdown the phone anymore! Shutdown sequence starts but never finishes (~60% battery drain over night after leaving in shutdown-sequence). Fortunately, the fastboot-keys do reset the phone! (Vol+&Power – thought my phone is dead since I cannot remove the battery, but found out accidentally) After the reset, the above quoted journalctl isn't shown – like mentioned, even the shutdown sequence doesn't succeed after the WiFi firmware crash. Also 'ifconfig' only hangs.

So two issues here: The firmware crash itself and the failure handling of the former. Unfortunately I don't know much about the Sailfish X architecture, but as far as I read, the firmware is inherited from partitions populated by vendor android distribution. Which would mean, the version I had installed before flashing Sailfish X control the hardware, right? In order to use different driver/firmware, one has to re-flash with vendor (Sony) image, right? (and then additionally Sailfish X again, which isn't a really bisecting friendly procedure, but flash wearing…)

Has anybody else seen WiFi firmware crashes starting with a specific Android base image version? I used the latest 8, afair.

Something similar happened to me until 3.0.2 but went away with 3.0.3. I even bought an XA2 Plus believing my X had died.

I have experienced the described behaviour two or three times since upgrading my Xperia X to 3.0.3 Hossa, but without such deep analysis as yours.

What makes things worse is that I configured the Situations app to switch Wifi depending on my current location (at home: Wifi on). Yesterday I found several hanging connmanctl processes (originating from such switching attempts), without being able to kill them.

Just to prove myself wrong, the hangup happened again today. It happened much more often earlier though.

I've experienced the same problem recently in Rome airport with my Xperia X too but XA2 worked fine.

I've the same Problem with my Xperia X with Sailfish I use a AVM Fritz!Box 7490 and a 1750E Repeater. Since last week, AVM added new feature access point steering per firmware update, it uses 802.11k and v wifi extensions for that. Now my XperiaX is crashing reproducable from time to time, when it's connect to wifi. If I disable the AP steering feature, it don't crash.

The crash also occurs in some public wifi, e.g. hotel wifi. I watch this during holiday.


I must revert my original post. Today my Xperia X crashed again in described environment. Sadly the behavior is the same as before update 3.2.0

Original post:

The Problem seems to be solved with update 3.2.0. My Xperia X don't crash anymore with band-steering enabled wifi connection to AVM Fritz!Box.

Thanks for the great analysis. This sounds like it could be related to my battery drain issues since the 3.0.3 update (https://together.jolla.com/question/205379/303-xperiax-battery-drain-when-bluetooth-wifi-on/) as that mostly seems to happen when I'm connected to a specific WiFi.

I will upgrade my device again today and verify if this is the case. I'll also try to evaluate which WiFi extensions are enabled for the specific WiFi.
