[Ovmsdev] Network stuck?

[Stephen Casner]

Because the STA wifi was present, the modem connection was not used,
but since the wifi was unstable, communication with the v2 server
failed and connections attempts from the web client mostly timed out.

This morning I changed wifi to client only, and now it is running
reliably even though my router still indicates weak signal strength.
So something about apclient mode makes this harder.
