    Hi all,
    so far I've always been using 63 chars wpa keys, and never had a problem. However I've lately found myself having to type it manually in more than one handset, and trust me, I don't really want to do it again! :-(

    After a quick google research I seem to understand that 63 is even too much and was thinking to use a 20 chars one instead (still with mixture of upper/lower case digits and punctuation, which gives still an incredible level of security (like few billion of billion years to be cracked, just kidding lol :))

    What do you think?

    Just make key then copy and past from program. 63¨128 is more than enough

    Based on http://www.lockdown.co.uk/?pg=combi and known compute speeds, I'd estimate a 12-character password with those symbols to outlast us all for many generations. Given the WPA key resets in flight on a regular basis, 20 characters is probably still overkill. And 63? Sheesh! =)

    BTW, there are (minor) known vulnerabilities in WPA/TKIP (really the latter). Would strongly advise WPA2/AES for maximum compatibility and security.

    Sorry I'm not sure I understand what you're trying to say...

    Thanks Rodney :) I'm actually already using WPA2/AES. I think I'll change it for something shorter very soon
