Hi, i have been posting here earlier as i thought my wifi stopped working after installing windows on parallels... i found out there is a different problem. when i turn wifi off and on and im looking through main menu wifi icon - it doesnt detect any networks. However, when i go to System Preferences -> Network and there i turn wifi off and on - a box show up with available networks, BUT the networks show up just for a second or two and then all of them disappear and im not able to connect even if i click on the network just in time before it disappears - gives connection timeout error(like the network is no longer available). Do you know whats the problem? please help.
