Public bug reported:
Wireless disconnects from networks randomly - sometimes connections OK
for days, other times for only a few minutes. Sometimes a wireless
power off/on or system standby/resume re-establishes connection, but
usually a reboot is required.
Wireless hardware and symptoms similar to bug 1437913, but different
laptop model. Log messages vary depending on the type of network being
used.
