Connecting to the Yun with Wifi.

Arduino Forum,

I am working with the Arduino Yun. I have configured and set up my Yun totally, it's webpanel works well and I have uploaded a few different programs onto it. I don't know hat happened but all of a sudden my arduino yun doesn't shw up in the ports menu when I don't plug it in. I should be able to connect to it through wifi but I can't. How do I fix this, this is very urgent. :astonished:

Thanks,
