  ping -I wwan0 wp.pl is not woprking no network istead.

So what's probably happening here is that at some point thenetwork is disconnecting you, you lose full data connectivity, butModemManager still thinks you're connected. It's been a long timesince I've tested a MBIM Huawei device, so not really sure if I'veseen them reporting network disconnections or not, but that is whatshould have been happening: when the network kicks you out, the modemrealizes that and sends a MBIM "Basic Connect" "Connect Notification"telling you that the activation state of the INTERNET context is"deactivated", see the basic_connect_notification_connect() method inthe mm-broadband-modem-mbim.c source file. If your modem is notsending you that notification, MM will still think the modem isconnected and you'll see the problem you're seeing.You should probably try to reproduce this problem running ModemManagerand looking for these notification messages; it could very well bethat we're not processing them correctly even if they arrive.--Aleksanderhttps://aleksander.es
