Test by simplifying the name for the wireless and set names for the two bands..


eg AE24ghz and AE5ghz.


Then use no security.. does the MBA and iphone then join..


If so put back security.. wpa2 with simple password, no spaces pure alphanumeric mixed case and numbers.


If no connection test with fixed channels .. say 11, 9, 6 in that order for 2.4ghz.


Don't worry about 5ghz for now.. if it still won't join it is somehow incompatible.. you need to reset the Japanese devices but I am not sure how.
