[Ovmsdev] wifi not coming all the way up?

For what it's worth, I have the default log level at Info, and have no
trouble getting WiFi to connect (with IP). 

That said, my module is currently in a state where both wifi and modem
have IP addresses, but the server can't (or won't) connect.  Stopping /
starting the V2 server hangs the module (no prompt returned).  Repeated
the test, and the bad state seems to occur just after the modem gets its
IP address.  Wifi connected or not, that's the last the module will talk
to anything else.
