This question is intended as an update to the original issue described here which is somewhat outdated and contains also some conflicting information.

From what I learned, only Xperia X devices are affected, regardless of the Sailfish OS version. At least I was not able to reproduce the issue with my Intex Aquafish.

Fact is that my Xperia X (currently SFOS shows the behaviour described below in my Wifi environment when the feature band steering/accesspoint steering (extension to the IEEE 802.11 Wifi standard) is activated in the Mesh settings of my Fritzbox 7590. The crucial feature seems to be accesspoint steering because the freeze also occurs when only the 2.4 GHz band is active.

When I force acesspoint steering by crossing accesspoint ranges (AVM repeaters), my Xperia X loses connectivity completely, reproducible. When that happens, neither Wifi nor mobile network can be used anymore. Even worse, both cannot be controlled anymore because connmanctl seems to hangs forever. That's why it is not even possible to restart or shutdown the phone. Soft reset is the only way to get out of this situation.

It seems the likeliness of the issue is related to the number of access points (four in my case). In my environment no other device is affected from this issue, be it iOS, Android, Windows, or Linux. The situation has not improved with the latest SFOS versions, th

@jovirkku - literally closed?, meaning that no more spammers or new users can sign up to TJC?

@jovirkku, I am confused: Jolla stated repeatedly, that the TJC content will be transferred to FSO.

Has Jolla now decided against transferring TJCs content to FSO?

@jovirkku I am confused: if the service has closed, how come that it is abused by spammers about daily -- spammers who easily register as new users. Spammers whose content gets ... transferred to FSO?

Because the public can still sign up for an account. I've just created this account for the purpose of answering this question. So, not closed as such.

With "the service has been closed" I meant simply that we do not discuss Sailfish-related issues and write answers in TJC any more. You should go to FSO and ask your questions and present your ideas there.

TJC was supposed to be read-only, until the significant contents have been copied to FSO. How, surprisingly, it is still possible to write here. Hopefully, we can go over this unpleasant transition period soon.
