network removed from wpa_supplicant.conf

[Christoffer Gurell]

Hi combined wisdom of mailing list!

I am seeing a strange behaviour on a number of devices that I am
hoping someone might help me shed some light on.

The wifi network the devices are connected to is of very low quality
(bad signal and high noise) but it still works enought for our
purposes. The devices seem to be temporarily blacklisting the AP every
now and then. This is not ideal but as long as they remove it from the
blacklist again I can live with this.

But some devices finally blacklist and remove the network (exactly at
the same time) from wpa_supplicant.conf. Never again attempting to
connect to that SSID unless i add it back manually.

My question is if there is anything in wpa_supplicant that could cause
this behaviour, like a "remove repeatedly blacklisted network under
condition N" or if I should look elsewhere in the platform for
something that may tell wpa_supplicant to remove and blacklist the
network for some reason.
