We have installed a device called , clever touch and it needs to be connected through wi-fi . But when ever ,we tried to connect that device, it is not connecting with the ARuba access point . and the clevertouch device is strucked in the step of " obtaining IP addresss " . after that there is no steps further . But we have tested the same device and it is connecting with other wi-fi ( moile hotspot ) , with any issue. I am beginner for the Auba Wireless , so its would much appriciated. , if some one guide me to fix this issue .
