Jolla C has strange behavior with WLAN and mobile data connection
My Jolla C shows a strange behavior when I´m on my desk at home and connected to Wifi. It has a pretty good signal connection (two to three bars on icon) but unfortunately the phone reconnects from time to time to Wifi again. (The Wifi-Station is in the next room 7 meter far away.)
So for example my screen is on and shows the notification screen. I can see it reconnects in irregular offsets. If the screen is off it goes on and I can see it is reconnecting again.
When I leave the building the phone is struggling between Wifi and mobile data connection. A few meter distance from home most of the time there is no data connection. Wifi nor Mobile Data. It seems the phone can´t decide what connection it should prefer. When I shut off Wifi manually it connects to mobile data and suddenly I get Push Notifications from eg. Twitter or my messengers.
Right now I´m sitting in a day office, connected to Wifi. I receive Push Notifications, no flashing screen, no reconnecting...
How can I figure out how strong really the Wifi connection on my phone is? Why it is always reconnecting? What I knew is the Wifi-Station here at the day office is a very old model, not the newest technology while the one at my home is a newer one.
Any suggestions or same experience? Because I think it isn´t a bug.
EDIT: I am retagging as bug because the answers confirm that it is due to wrong handling of rekeying. I hope this is enough to get it on Jolla's to-do list. --Federico
you could try the app "WiFi Analyzer" to see the signal strength

Welcome to TJC. :)

As far as I know this bug is still present. I personally am still affected. Whatsapp messages, for instance, have wrong timestamps, sometimes even in the future (which is weird).
Federico ( 2016-09-08 15:34:29 +0300 )editHowever, the broken push notification problem is independent of signal strength, afaik it happens on some kind of wifi routers/providers with specific connection timeout settings
till ( 2016-09-08 15:42:02 +0300 )edit@till That's only a conjecture. The true cause for the bug has never been identified. Actually it has been verified that sending packets at regular intervals doesn't fix the problem, so this suggests that it may not be related to timeouts after all.
