You didn't tell us how you entered the password (editing wireless config manually with vi, or using the gui). Assuming you edited your wireless configuration with vi, you likely forgot to enclose your password in single quotes, or - if your password itself contained single quotes - failed to properly escape them.

The wireless password must be between 8 and 63 characters long if it is in ASCII notation. A 64 character password is allowed, but must be given in hexadecimal notation. So either 8 to 63 random characters or an exactly 64 character long hexadecimal string.

Note the special characters such as

$ ` ' "

may cause problems when improperly escaped.

When setting the password

special " character ` password $ test ' string

via the gui, the following notation will end up in /etc/config/wireless:

option key 'special " character ` password $ test '\'' string'

Note how the special ' character got escaped.

Also, please don't double post!

  • Also, I'd suggest you setup your WiFi on a wired connection.

I have tried this on my router and 63 characters work just fine for me. Something must be wrong with your password as @jow mentioned.

thank you to all first
then you Enable key reinstallation (KRACK) countermeasures ??????

Yes I also tried with KRACK and without it. 63 characters just work fine for me.

It seems out of place to use 63 characters for a WiFi password unless you are on a military-grade access point but then again I dont think even they will have time to put 63 characters to access internet or other servers. How do you manage to remember such long strings of passwords?

yes :rofl: :joy:

max 57 characters in my router tp-link w8970
i save the password wifi into my computer in text file !
this accept 64 : 4FB70EFD9C5FB4D0A1E2C6FD4D3A7D074FB70EFD9C5FB4D0A1E2C6FD4D3A7D07
this not accept ! : !@o4UfEzXE8rE0roN-spiVAsoK?p99uT+gEkAri!8bij$Y2t+ni0=+o4o_l7OS?
is this : !@o4UfEz
small to : !@o4UfEz*XE8rE0roN-spiVAsoK?p99uT+gEkAri!8bij$Y2t+n ( work and accept )

!@o4UfEz*XE8rE0roN-spiVAsoK?p99uT+gEkAri!8bij$Y2t+ni0=+o4o_l7OS? is 64 byte, not 63. Simply remove one character.


thank you but this 64 ! accept !
and in this
try delete !@o4UfEzXE8rE0roN-spiVAsoK?p99uT+gEkAri!8bij$Y2t+ni0=+o4o_l7OS? ( ? )
XE8rE0roN-spiVAsoK?p99uT+gEkAri!8bij$Y2t+ni0=+o4o_l7OS ( accept )

Because this is in hexadecimal notation (Only characters a-f and 0-9).

This is not in hexadecimal notation (has characters other than a-f and 0-9).

Hexadecimal = exactly 64 chars, not more, not less
Not hexadecimal = between 8 and 63 chars. Not less than 8, not more than 63.


the best encryption used hexadecimal or characters ?

I personally use a pass-phrase when human entry is required more than occasionally. For example

This could be a good phrase, except that it's been posted!

Both get converted to a full-length "hex" string, so it is the information content and "guess-ability" that is important, not the way it's entered.

$ wpa_passphrase some_ssid "This could be a good phrase, except that it's been posted!"
	#psk="This could be a good phrase, except that it's been posted!"

Note that wpa_passphrase is likely only present on "desktop" systems.



A passphrase is just the ASCII representation (63 characters) of the REAL Hex key (null + the 63 hexes of the characters.

The key itself is rarely seen or used by the human user - unless you're hacking. :wink:
