And yes, we are using the latest Generic firmware. Actually, that fw update was the thing that triggered us to look into the problem, as the failure to connect quickly then appeared to happen more often than before. We have seen the problem (although apparently much less frequent) on older installations also.

It is version 1.22.2. There is no change when adding --set-expected-data-format. Below is the log: Btw, the Linux kernel is compiled without IPv6 on this system. That is why we have specfied ip-type=4. But maybe it is still related to the kernel not supporting v6 here? # Checking that we are not connected and that autoconnect is not enabled $ qmicli -d /dev/cdc-wdm0 --wds-get-packet-service-status [/dev/cdc-wdm0] Connection status: 'disconnected' $ qmicli -d /dev/cdc-wdm0 --wds-get-autoconnect-settings Autoconnect settings retrieved: Status: 'disabled' Roaming: 'allowed' # Seems OK # Settings expected data format $ qmicli -d /dev/cdc-wdm0 --set-expected-data-format=802-3 [/dev/cdc-wdm0] expected data format set to: 802-3 # Check which data format we have $ qmicli -d /dev/cdc-wdm0 --wda-get-data-format [/dev/cdc-wdm0] Successfully got data format QoS flow header: no Link layer protocol: 'raw-ip' Uplink data aggregation protocol: 'disabled' Downlink data aggregation protocol: 'disabled' NDP signature: '0' Uplink data aggregation max size: '0' Downlink data aggregation max size: '0' # Change to 802-3 $ qmicli -d /dev/cdc-wdm0 --wda-set-data-format=802-3 [/dev/cdc-wdm0] Successfully set data format QoS flow header: no Link layer protocol: '802-3' Uplink data aggregation protocol: 'disabled' Downlink data aggregation protocol: 'disabled' NDP signature: '0' Downlink data aggregation max datagrams: '0' Downlink data aggregation max size: '0' # Seemed to work. # Just check again to be sure $ qmicli -d /dev/cdc-wdm0 --wda-get-data-format [/dev/cdc-wdm0] Successfully got data format QoS flow header: no Link layer protocol: '802-3' Uplink data aggregation protocol: 'disabled' Downlink data aggregation protocol: 'disabled' NDP signature: '0' Uplink data aggregation max size: '0' Downlink data aggregation max size: '0' # Start the network manually $ qmicli -v -d /dev/cdc-wdm0 --wds-start-network=apn=internet,ip-type=4 --client-no-release-cid [15 Apr 2020, 08:40:59] [Debug] [/dev/cdc-wdm0] Opening device with flags 'auto'...
