I’m requesting help configuring a Sierra Wireless GL7500 so that it will hot plug. I’m working with a system for which the USB cell modem can be momentarily unplugged and plugged, and we need to recover cell service when that happens. The modem was set up according to your knowledge base article: link text I’ve attached a log file with the output of mmcli and other utilities to show the behavior through a link text disconnect/reconnect of the modem.
Basically, after the disconnect the cell modem enumerates as a different device, it is reinstantiated as a new modem object with a new bearer object. NetworkManager fails to connect the bearer. Hopefully this is a simple configuration issue that you can help me with!
