Revision history [back]

I observe following bug on my Jolla C for about 3 months. In subway mobile data transfer works for couple of minutes and then stops working. Connection icon is still shown but packages do not pass through. The device becomes effectively offline, though SailfishOS supposes it is still online. It is enough to trigger airplane mode on/off or restart network connections and after the device reconnects to mobile network data transfer works for another couple of minutes. But in places other than subway carriages mobile data works reliably.

Finally I became frustrated with requirement to trigger airplane mode manually every several minutes and wrote stupid script, that tries to ping and triggers airplane mode if there is no response. Though it is not a solution but a duct tape workaround.

I've asked recently at https://t.me/sailfishos and discovered a couple of more users noticed similar issue. They use different mobile network operators, BTW.
