Can't connect in WPA/PSK TKIP

[calimero]

Hello,

I use to connect from my laptop (ibm T40) to my wl-500g. I use the WPA/PSK and TKIP setting and it works from now.

Two days ago I installed a wifi access in my company which is very high securised (radius and a lot of other stuff). In order to connect to this wifi access I had to install an IBM client that call IBM Access Connection.

Since this time, i do not have access to the windows parameter to see the parameter of the wireless access. I use the IBM tools to do it. So i put my parameter in it, but I was unable to connect to my wifi access at home. I can connect when I do an open point (no security), with a wep key, but not with a wpa/psk + tkip. It keeps not working. One strange thing is that the IBM tool propose to choose between 2 type of psk key one with 8 to 63 alphanum char (0-9, a-z) or another with 64 hexa char (0-9, a-f).

When I try to use the hexa option, i've got a problem, the IBM tool want exactly 64 char, whyle the asus need less than 64 char (so max 63).....
of course the alphanum does not work....

Any of you have an idea why it is not working ?

Thanks for your help

The wl-500g wants an ascii passphrase for wpa-psk - this has a limit of 63 characters. These characters are hashed with sha1 to create a 256 bit key (64 "hex characters"). Therefore the 8 - 63 character option in the IBM software is without doubt the right choice.
I suppose you have a passphrase that is actually not 63 (ascii characters) long but shorter. Maybe the algorithm used to fill up the missing characters, before the hash is created, is different on the IBM software compared to the wl-500g. So retry with a 63 (ascii character) passphrase and let us know if it works!

I tried, but it didn't work.

I reboot my laptop (for the tenth time) and then like a miracle it works. I can't explain what happend, but it works, so it's cool for me

Thanks for the help
