[Ovmsdev] Poor wifi performance

Hi Steve,
Ok, so, still a puzzle as to why the crashes. Fortunately, I've only
had the one. I've not had any trouble losing wifi connectivity, either
when the car's been sitting in the garage for a few days, or coming and
going on errands (so, transitioning to cell and back). Prior to this, I
think the last boot was the upgrade to 3.1.008. Oh, perhaps the car's
recent near death experience (*) cycled power? Not sure, but probably
did. Anyway, in general, I've not had trouble with connectivity in a
long time.
The only thing I've noticed is that sometimes I have a rather long delay
between an event (e.g. when the car starts charging) and having it show
up on my cell phone. Usually I get it immediately, but some time it's
delayed several minutes, and once in a while it never shows up (e.g.
charging started but never finished). It might simply be packet loss on
my Internet connection (it's fast, but sometimes leaky), not related to
wi-fi. I get delays at times on the PC going to websites too.

(*) For some reason, the VMS lost connectivity to the VDS, and the car
locked up. Fortunately it was in the garage, and the windows were
rolled down since the door opening switches stopped working too. Had to
unplug the cables to the VMS under the dash and plug them back in to
force a reboot. {phew!}
