[Ovmsdev] WiFi client not switching to better AP

[Michael Balzer]

Steve,

that's something we can control.

If you don't mind frequent disconnects in poor Wifi situations, a simple 
solution now is to attach a "wifi reconnect" command call to the 
"network.wifi.sta.bad" event. I added that command on the Wifi rework 
some months ago.

For a better, general solution, we could e.g. count the 
"network.wifi.sta.bad" events on the same network (or better: check the 
event frequency) and disconnect when reaching some (tunable) threshold. 
The next automatic scan then connects to the best network available. 
Getting stuck in the "bad signal" state for too long would also need to 
trigger a disconnect.

Regards,
Michael
