Hi, I have a late 2009 iMac and with Snow Leopard I never had Wifi problems. Since updating to Lion back in July, I have been experiencing wifi disconnections. At first it was happening twice a day but I find that it got worst now and it can happen 10 times in an hour. Is there anything that can be done to solve this wifi issue? I have an early 2010 13' MacBook Pro and it doesn't disconnect at all with Lion installed. Thanks in advance!
