About a month ago I bought the new mid 2011 iMac (21.5") model and have been happy with it. That being said I have experienced some Wifi issues lately. When I turn on the machine there is no connection to the internet even though it says that machine is connected. I then have to turn of the wifi and connect again - then it works!? Sometimes the connection is not chosen by default and I have to manually connect to my wifi network... Have any of you had the same issues with wifi? Maybe it is just a simple Lion bug/issue?
