Public bug reported:
Binary package hint: indicator-network
Yesterday I replaced my old TP-LINK router with a new one (TL-WR1043N
type) that supports b,g and n standards and initially left it at the
default mode (mixed bgn, auto-negotiate). When I connected my Dell
Latitude 2100 netbook I found the network indicator icon had vanished,
though the networking was working and it would still flash up the notice
on the network being established or lost.
After messing around with some suggestions from the Ubuntu forum
(assuming it was the netbook and not the change of router) I found that
disabling and re-enabling the wifi card using Fn+F6 keys brought the
icon back, but it was showing the network as disconnected (exclamation
mark next to the signal strength 'fan' pattern) even though it was
connected. On rebooting the icon was almost invisible and several times
wider than usual (yes, very odd!)
Then I tried configuring my router to be limited to only b & g speeds
and then the icon was back to normal, showing the signal strength
correctly and behaving normally if I clicked on it, etc.
I have now tried reverting to 'bgn' and the icon was OK until I
rebooted, and then it was gone again (network fine) and on restoring the
router to limit it to b &g only, it came back to normal.
So clearly there is something about the data that is coming back from
the wifi hardware that is not being parsed properly, and more worrying
(the strange loss of icon and the occasion it was misshaped) probably
corrupting something internally (i.e. not sanitised correctly).

Only obvious difference to me is with 'n' enabled it has my bit rate as
zero, where as with b & g only it reports a realistic value. Still, that
should not kill the icon surely?
