Hi Aleksandar,
looks like a somewhat strange regulatory handling. However, I'm not really
familiar with the regulatory stuff. Maybe Luis can give us some info/ideas
regarding this ...
Luis, mind to have a look at the regulatory messages below?

We received an empty country IE and as a result disabled serveral 11a channels.
Maybe even the one we are currently associated to?

Yes, there is something fishy with it.
this is what is allowed for Ireland
country IE:
(2402 - 2482 @ 40), (N/A, 20)
(5170 - 5250 @ 40), (N/A, 20)
(5250 - 5330 @ 40), (N/A, 20), DFS
(5490 - 5710 @ 40), (N/A, 27), DFS
Apparently IE Ireland does allow 5Ghz channels, and something is
really strange is going on.
Maybe if the Airport Extreme was changed to a new channel, it would improve.
But I'm not totally sure.
We might also be looking at an old regulatory daemon or database.
