Title:
wi-fi continually fails to connect (after previous success)
Status in network-manager package in Ubuntu:
Incomplete
Bug description:
Wi-fi had been working fine, but this morning, nothing doing.
syslog shows many instances of:
<warn> Activation (wlan0/wireless): association took too long, failing
activation.
Some info which may or may not be relevant:
Removing the network and adding it made no difference.
Deactivating, then reactivating the hardware wi-fi network switch made no
difference.
This was happening on two independent wi-fi networks (my hotel and the
bluefin office)
Rebooting fixed the issue.
Closing the laptop did not reliably send it to sleep last night.
Two competent Canonical engineers were unable to diagnose the problem.

I have attached my syslog starting just before the most recent successful
connection until
just before I rebooted.
