Marking Triaged Low as mainline tested and multiple WORKAROUNDs.
** Summary changed:
- Wireless not connecting on bootup in 12.04 (Intel Wifi Link 5100)
+ 8086:4232 Wireless not connecting on bootup in 12.04 (Intel Wifi Link 5100)
** Description changed:
+ Sometimes after booting Ubuntu, the wireless connection is not operational
(e.g. ping in a console window shows nothing), although the network manager
icons shows that connection is established.
+ It is more likely (almost 100%) to happen if the machine hasn't been used for
several days (which suggests to me it has something to do with obtaining dhcp
leases). And even with the steps below, sometimes the wifi will work from the
beginning as expected.
+
+ However, steps that increase the chances to reproduce it are:
+ * boot into ubuntu.
+ * turn off wifi with the rfkill switch
+ * sudo rm /var/lib/dhcp/dhclient*
+ * reboot the system. At the GRUB screen, turn on the rfkill switch again, so
that wifi is enabled at boot time
+ * log into ubuntu. network manager will show a "wifi connected" icon (which
is not the whole truth).
+ * open up a console window and type "ping www.ubuntu.com". Nothing will be
shown on the console
+
+ Tested with linux-
+ image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb. For now,
+ wifi seems to work with this kernel.
+
+ WORKAROUND: * turn off rfkill switch. Wait until network manager popped up a
message saying "wifi disconnected"
+ * turn it on again
+
+ WORKAROUND: * boot with wifi disabled by the rfkill switch
+ * turn it on only *after* having logged in to your session
