Hi there,
It seems that my modem supports pretty much all modes:
Modes | supported: allowed: 2g; preferred: none
| allowed: 3g; preferred: none
| allowed: 2g, 3g; preferred: 3g
| allowed: 2g, 3g; preferred: 2g
| allowed: 2g, 4g; preferred: 4g
| allowed: 2g, 4g; preferred: 2g
| allowed: 3g, 4g; preferred: 3g
| allowed: 3g, 4g; preferred: 4g
| allowed: 2g, 3g, 4g; preferred: 4g
| allowed: 2g, 3g, 4g; preferred: 3g
| allowed: 2g, 3g, 4g; preferred: 2g
| current: allowed: 3g; preferred: none
However, when I'm trying to set the preferred mode to 4g, I'm getting this:
pi@okamoto:~ $ sudo mmcli -m 0 --set-allowed-modes='3g|4g'
--set-preferred-mode='4g'
error: couldn't set current modes:
'GDBus.Error:org.freedesktop.libqmi.Error.Protocol.Internal: QMI protocol
error (3): 'Internal''
