<div dir="ltr"><div>All, So I wanted to disable my modem from trying to connect to 2G because I saw some threads that says that Sierra modem firmware conks at times when they try to connect to 2G. I have a Sierra AC314U modem. So I said qmicli -d /dev/cdc-wdm0 --nas-set-system-selection-preference='umts|lte' - basically saying that use only 3G and LTE. After that point the modem goes back to "Ready to connect" state. Now I try using - qmicli -d /dev/cdc-wdm0 --wds-start-network=broadband --client-no-release-cid to initiate the connection (which is what I usually use to connect and it works). But after that point the modem refuses to connect even though the --nas-get-system-info option shows available 3G/LTE networks. So I suspected that its because the nas-set-system-selection-preference says that a modem reset is needed, and I did not reset the modem. So I forced a reset using the below pair of commands, but after the reset the umts|lte selection I made is thrown out and its back to gsm|umts lte. So thats a chicken and egg problem. qmicli -d /dev/cdc-wdm0 --dms-set-operating-mode=offline qmicli -d /dev/cdc-wdm0 --dms-set-operating-mode=reset </div>So my question is: If the "--nas-set-system-selection-preference='umts|lte'" needs a reset and the setting is wiped out after a reset, how exactly do I do that ? Any guidance will be appreciated! Rgds, Gopa. </div>
