NetworkManager auto-connect GSM module is not stable
Hi NetworkManager authors, *** What I except: I want NetworkManager can auto-connect the GSM module in my board when reboot every time, So I set the 'connection.autoconnect' to 'yes' and set the 'connection.autoconnect-retries' to 3. What I encounter: I found that the NetworkManager auto-connect GSM module is not stable, sometimes it works fine, but sometimes it is not ok What I find: I checked the log of NetworkManager in syslog and found that NetworkManager tried to connect the GSM module only once in the condition auto-connect failed. I have set the 'connection.autoconnect' to 3 and why does NetworkManager reconnect only once sometimes? *** 1.
