With Snow Leopard I had no problems waking my new iMac with LogMeIn Ignition. I could also stream movies to my iPad and iPhone, using AirVideo, at any time. Yesterday I clean installed Lion, re-installed LogMeIn and Air Video. Now, anytime my iMac goes to sleep I cannot make a connection using the LogMeIn or AirVideo app on my iPad/iPhone (i.e. I cannot Wake my iMac). Any ideas on this? Others experiencing these problems? Did any settings regarding Wake on Demand change with Lion? Thanks for any help.
