I don't have a Radio TTL'd at the moment, so I can't confirm this:
I would guess that the re-association generates a WPA "CONNECTED"
message that would cause the -wpa_cli- -wpa_action- script to do:
Code:
--------------------
# Kick DHCP client to do a renewal
kill -usr1 `cat /var/run/udhcpc.$IFNAME.pid`
--------------------
Plausibly, the result of this could have resulted, in an environment of
poor connectivity, a failure to do a proper renewal. The consequences of
that on "Check Network" could be various... I shall not speculate
without reading through the code.
Incidentally, the -wpa_action- script fails on a WPA "DISCONNECTED"
message because the busybox shell doesn't seem to like an -if- clause
with no command inside it. But it didn't have to do anything anyway, so
it shouldn't matter. Having said that, I wonder how -wpa_cli- would
respond to the failure...
I'll have a go the next time my Radio is TTL'd to see what really
happens.
