Im able to connect to my 350 with both an ipad and iphone. However the connection constantly skips frames and buffers after ~10 mins. 75mbps on the ulpoad (slingbox side) and 75 mbps on the download side (remote location). Also, my chromecast is now hardwired with the ethernet adapter, so no blaming the wifi here. As you said, problems with chromeacast have been visible on this forum for many months. But sling doesnt have any answers, or even responses.
