When I paste my WPA2 password/shared key (45 random including many special characters)in the wifi settings the "Join" button is greyed out. When I backspace 3 times from the end of the character string,the button turns blue. Of course, the password is wrong and will not connect to my home router. Anyone else have this problem? Is there a 42 character max? If I disable router security settings, the phone connects flawlessly, so I don't seem to be having any hardware problem..

Dell Inspiron 1720, Windows 7

    having the same issue only it is at work and with 62 character key. But as you stated when I back space 3 i get the join button to highlight. Did you ever figure this out? Unfortunately I do not have the option to change any router settings. This passkey worked just fine for my 3GS, but when I upgraded to iphone 4 It is not letting me enter the full key.

    Hi there,

    If it is any consolation, we identified a WPA2 key problem when 4.2.1 was first released and it is simply broken. We have reported it to Apple and we await a fix (yeah right) in the next release but we are not holding our breath.

    Yes, there is a key length issue and it does not matter how long the key is, it simply does not work properly in some 'phones and we cannot isolate the reason behind some working and others not. All we can say for certain is that the handsets were able to connect pre 4.2.1 and now they cannot ergo it is 4.2.1 that is at fault, but don't say it too loudly on these forums - you tend to upset those who don't have the problem!

    SHARK!

    Apple really needs to get this fixed. My new iPhone 4 Verizon will not connect with my home network TimeCapsule either using a long WPA2 key, but if I use the shorter key on my guest network it works fine.
    So, Apple, is there a limit or not? If not, why doesn't my iPhone connect?

    You aren't talking to Apple here. This is a user-to-user help/discussion forum hosted by Apple.

    Someone here might know the answer to your question but you might do better to try contacting Apple technical support.

    By the way, these very long WPA2 keys do not really provide any extra security and are just a nuisance.
