4.1 on an iMac dual core intel as my main OS.

Until today, the wifi network was working fine, but suddenly as i started again my computer this afternoon, i cannot find wireless connections in my network settings. My wifi works perfectly as i have another computer and my spartphone connected to it and browsing with no issues.

i have run lshw -C network from the terminal and here is what get:
