Hallo mein ipad2 kann sich nicht an wlan5GHz anmelden

Question

Hey,
kann mir jemand sagen, wieso mein i-Pad 2 sich nicht an das 5GHz-Wlan der Fritzbox 7490 anmelden kann?
- Der WPA2 Schlüssel ist vergeben, 2,4-GHz-Verbinduungen laufen
- In der Fritzbox ist das 2,4-GHz und das 5-GHz-Band aktiv
Das I-Pad kann die Verbingung nicht herstellen..."Verbindung zum Netzwerk "wlandg5GHz" fehlgeschlagen"...
Sind irgendwo noch weitere Einstellungen erforderlich?
Danke für Euere Hilfe!!

Hello & welcome!
Sorry that I don't have fluency in germanic languages so I had to use google translate.
Their application suggested your question (as translated by them) says:
"Hi My Mac (will) not turn off because of the ibook, it is simply that it can not turn what should I do?"
https://translate.google.com/
You could try Force Quit to select the ibook related application from the  Apple menu, to see
if that helps. You may also be able to press & hold the power button, until Mac shuts off... This
may not work if you'd set the preference for on-off button, to enable sleep instead of off.
Could be you may need to check & repair the computer hard disk drive as well as repair disk
permissions; you could  do that by accessing Recovery's OS X Utilities, and run Disk Utility
to choose 'repair disk' and also, separately, 'repair disk permissions'. Then restart into OS X
from the main system in the computer.
Another different resolution, once you can make the computer quit, would be to try SafeBoot
where you start up (shift key held) until you see Login, then continue and use Disk Utility in
the running OS X, to repair disk permissions; when done, restart & let it boot naturally. You
can also use Console utility logs to see the Time/Date entries about the time of the problem.
Sorry to not be fluent in any language.
Somehow, I manage to make due with this default one.
