Hello there. I have this behavior in my raspberry PI where a modem shows connected, but I still can't connect to the internet: -------------------------------- General | path: /org/freedesktop/ModemManager1/Modem/4 | device id: ab1573a4186ee4930c3dbe7ee14e2dddcd10b4c2 -------------------------------- Hardware | manufacturer: huawei | model: E3276 | firmware revision: 21.260.05.01.150 | supported: gsm-umts | current: gsm-umts | equipment id: 866519011156587 -------------------------------- System | device: /sys/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2.2 | drivers: huawei_cdc_ncm, option | plugin: huawei | primary port: cdc-wdm0 | ports: cdc-wdm0 (at), ttyUSB0 (at), ttyUSB1 (at), wwan0 (net) -------------------------------- Numbers | own: +xxxx -------------------------------- Status | unlock retries: sim-pin (3), sim-puk (10), sim-pin2 (3), sim-puk2 (10) | state: connected | power state: on | access tech: umts | signal quality: 41% (recent) -------------------------------- Modes | supported: allowed: 2g; preferred: none | allowed: 3g; preferred: none | allowed: 4g; preferred: none | allowed: 2g, 3g, 4g; preferred: none | current: allowed: 2g, 3g, 4g; preferred: none -------------------------------- IP | supported: ipv4, ipv6, ipv4v6 -------------------------------- 3GPP | imei: 866519011156587 | operator id: 72416 | operator name: Oi | registration: roaming -------------------------------- 3GPP EPS | ue mode of operation: csps-2 -------------------------------- SIM | primary sim path: /org/freedesktop/ModemManager1/SIM/4 -------------------------------- Bearer | paths: /org/freedesktop/ModemManager1/Bearer/5
Weird thing is that on my Ubuntu desktop this modem works! The only difference I noticed is that in my Ubuntu field 'access tech' is 'lte', while above (on the pi) like you can see it's 'umts'. I figured the problem might be related to the 'access tech' field above, so I tried forcing setting mode for '4g' but didn't work: *$ sudo mmcli -m 4 --set-allowed-modes='4g' --set-preferred-mode='4g'* error: couldn't set current modes: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unsupported: The given combination of allowed and preferred modes is not supported' The only difference between my raspberry pi and my desktop machine is that the pi is under a more recent version of ModemManager 1.16 vs 1.12 from my desktop Ubuntu. Any ideas?
