Plugging in the dongle after a boot and issuing ifup wan does nothing. In addition, I found that unless the NCM dongle is 'up and ready' before (re)booting (ie, has been powered up via a hub and left for a minute or so, with the status light progressing from, in my case, flashing green [GPRS] to flashing cyan [LTE]) no connection is made. No errors or anything written to log. I experimented with option delay '30' but it made no difference. This also has an impact on any scripts that need an external interface to be up. I need autossh to come up after wwan0 has made a connection, but with the current set up it is called well in advance of a connection being made; plays havoc with remote setup...
