Apparently, some users have had problems with the WiFi connection of your Mac. While this may not bother some people, are sure to fall very badly to others. WiFi chips used by Apple are also used in many other devices, so the problem does not seem to come from that side, but still, the hardware is controlled by the software , and in this case it appears that the energy manager of the operating system Mac OS X Lion is the source of the problems with WiFi.
Some users of Apple Forums contacted the suppliers / vendors of routers, and they asked them to deactivate the power manager on their machines to avoid the loss of connectivity. And apparently it solved the problem.
What had happened here? Well, basically, the problem was between certain routers and OS X Lion: to enter the idle WiFi chip, and subsequently be summarized, connectivity with the router was not reset properly. It is not clear who should solve the drawback: if router problem must be the manufacturer, and if the side of the operating system is Apple responsible. Note that this problem has been presented only for OS X Lion.
Does anyone around here has had this problem? If the case is that, try turning off the power manager on the Mac
