Blackberry failed to associate with the network

This error comes when try to set up WiFi on a blackberry bold device.

Solved by applying the following solution from blackberry forums
"the first thing to do is a battery pop reboot. With power ON, remove the back cover and pull out the battery. Wait about a minute then replace the battery and cover. Power up and wait patiently through the long reboot -- ~5 minutes. See if things have returned to good operation."
