WPA2 maximum password length?

Hello,

Am I right in saying the WPA2 maximum password length the EZCast M7 supports is 8 characters? Is there a reason why it can't support 63/64 characters?

Thank you,

Ian

Dear Ian:

Sorry for the inconvenience. EZCast Supports at most 63 characters WPA2 password for AP router.
Thanks for your understanding.

Hello,

I just bought the EZCast Music device (http://www.iezvu.com/download_tool.php?&l=en) and after several tests it seems that it does not handle my 44 chars WiFi Password. I tried with a 20 chars password and it worked, but when I put back my 44 chars it does not. I do not want to permanently change my WiFi password as it is used on all my other devices at home.

to set this password into the EZMusic device I tried: iPhone and iPad apps, Webpage using a PC, my device details are:

EZMusic
SSID: EZMusic#D96023A7
MAC: 8C:18:D9:60:23:A7
Firmware Version: 14208000

Could you please fix this bug via a FW update ?

Regards,

Hello,

I made some more tests and I found that a 33 characters password works, but a 34 characters password does not.
So 33 characters is the limit, but as you stated, 63 characters must be the maximum allowed passphrase length.

https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access#cite_ref-10
This key may be entered either as a string of 64 hexadecimal digits, or as a passphrase of 8 to 63 printable ASCII characters.


My device details:
EZMusic
SSID: EZMusic#D96023A7
MAC: 8C:18:D9:60:23:A7
Firmware Version: 14208000

Having this corrected would be really great :|

Hello Henri,

I updated my EZCast Audio to version 14818000, WiFi password seems now to be limited to 40 characters.
This is better but still not conform to the WiFi Alliance requirement which must be 63 characters.

Sadly my EZCast Audio will go back to its box.

Regards,
