I am using the windows wireless manager. I used an application to generate a random 128 bits hex key (26 characters) and paste into the router configuration. Then I paste the same hex key in my laptop when prompted for the key. It does not tell me if the key is correct and it say acquiring address, after a while, it just assign automatic private address. All the other settings of the router is default, I only changed the ssid and enabled 128bits encryption.
