I am using MM 1.14.6 (from Deiban buster-backports) with Quectel EC21 (qmi).
I can successfully set the allowed mode to "3G" and get a UMTS connection :) * mmcli -m 0 --set-allowed-modes="3G"* However, if I try to lock to 4G the connection *never succeeds* :( ** mmcli -m 0 --set-allowed-modes="4G"** The only way I can get an LTE connection is with the following. ** mmcli -m 0 --set-allowed-modes="3G|4G" --set-preferred-mode=4G** *Is this a bug?* *Is there any other info I can provide to help resolve this so I can use: **** mmcli -m 0 --set-allowed-modes="4G"*** Thanks, Brendan.
