DGN3500 WPA2 unselectable

[chikles]

 ho un DGN3500 ho la necessità di passare da WEP a WPA2.
Solo che mi permette di selezionare solo WEP, le altre connessioni non sono selezionabili. Come mai?
Come posso risolvere il problema?

Grazie in anticipo

I have a DGN3500 I need to switch from WEP to WPA2.
Only that allows me to select only WEP, the other connections are not selectable. Why?
How can I fix the problem?

Thanks in advance

Try a factory reset.

Try switching from WEP to None, Apply, then switching to WPA2 and Apply.
