AP WN604 used as client - doesn't work

Hello guys,

I've just tryied to use an AP WN604 in client mode, but:
My needing is to use the AP as a wifi device, adding into an industrial pc, because in this PC there isn't a WIFI card.

My settings are the following:
CONFIGURATIONS --> WIRELESS BRIDGE ---> CLIENT (true)
MAC CLONE ---> DIsabled
For the rest I've used the DEFAULT settings.

I imagine that I will see into the page MONITORING ---> WIRELESS STATIONS
a list of the WIFI to connect with my WN604, but nothing... and the button Refresh doesn't work.
Any suggestion, please?
Thank you in advance,
Aldus
