Hi,
I use a “Quectel Wireless Solutions Co., Ltd. RM520N-GL“ and mmcli version: 1.20.4 to connect to cellular neworks (in this example 1nce-network) After setting the initialbearer *mmcli -m any --3gpp-set-initial-eps-bearer-settings="apn=iot.1nce.net <http://iot.1nce.net>,ip-type=ipv4v6"* Modifying the nmcli connection *nmcli c mod wwan gsm.apn iot.1nce.net <http://iot.1nce.net> autoconnect yes* and trying to bring up the connection. *nmcli c up wwan* The modem takes a really long time to connect to the network. It seems that the nmcli does wait for the *modem state* to be *connected*. I did grep the journal of mmcli to check what is taking that long and I got some warnings in *simple connect state (6/10): register*. *Aug 16 08:26:09 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (roaming -> registering)* *Aug 16 08:26:09 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (registering -> roaming)* *Aug 16 08:26:10 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (roaming -> unknown)* *Aug 16 08:26:10 cmtk ModemManager[456]: <info> [modem0] state changed (registered -> enabled)* *Aug 16 08:26:19 cmtk ModemManager[456]: <info> [modem0] simple connect started...* *Aug 16 08:26:19 cmtk ModemManager[456]: <info> [modem0] simple connect state (6/10): register* *Aug 16 08:26:26 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:26:36 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:26:47 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:26:56 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:27:06 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:27:17 cmtk ModemManager[456]: <warn> [modem0] couldn't reload extended signal information: No way to load extended signal information* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] network reject indication received* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] service domain: ps* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] radio interface: 5gnr* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] reject cause: (null)* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] mcc: 262* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] mnc: 1* *Aug 16 08:27:19 cmtk ModemManager[456]: <warn> [modem0] closed subscriber group: 27* *Aug 16 08:27:19 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (unknown -> idle)* *Aug 16 08:27:19 cmtk ModemManager[456]: <info> [modem0] simple connect started...* *Aug 16 08:27:19 cmtk ModemManager[456]: <info> [modem0] simple connect state (6/10): register* *Aug 16 08:27:20 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (idle -> unknown)* *Aug 16 08:27:21 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (unknown -> registering)* *Aug 16 08:27:21 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (registering -> roaming)* *Aug 16 08:27:21 cmtk ModemManager[456]: <info> [modem0] state changed (enabled -> registered)* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (roaming -> registering)* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] 3GPP registration state changed (registering -> roaming)* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] simple connect state (7/10): wait to get packet service state attached* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] simple connect state (8/10): bearer* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] simple connect state (9/10): connect* *Aug 16 08:27:22 cmtk ModemManager[456]: <info> [modem0] state changed (registered -> connecting)* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] QMI IPv4 Settings:* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] address: 100.76.105.26/30 <http://100.76.105.26/30>* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] gateway: 100.76.105.25* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] DNS #1: 8.8.8.8* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] DNS #2: 8.8.4.4* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] MTU: 1500* *Aug 16 08:27:23 cmtk ModemManager[456]: <error> mm_utils_bin2hexstr: assertion 'bin != **NULL' failed* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0/bearer3] reloading stats is supported by the device* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0] state changed (connecting -> connected)* *Aug 16 08:27:23 cmtk ModemManager[456]: <info> [modem0] simple connect state (10/10): all done* *It seems like the connection process takes a long time during the errors “couldn't reload extended signal information: No way to load extended signal information”.* Any idea or recommendation, how I can fix it? Thanks a lot! Best regards, Dominik
