As of yesterday my Sling for Android stopped working on wifi. Mine is not an isolated issue. Many people have been having problems that just started days ago. Of course support is blaming the phone even though it works on 3g and my laptop. When I log on to my Sling account online I get a message "slingbox software staus: warning" which is explained as a firmware update issue. However there is no update available! Sling is great when it works but I think as soon as they get some competition their lack of support is going to kill them.
