I haven't used my Slingbox 500 in 1.5 months. This weekend it failed to work because it was not connected to the network. When I got home I tried to connect it to my home wifi but repeatedly got incorrect password messages. I am sure the PW is correct and I tried two different networks but nothing worked. I unplugged the unit to restart it but that didn't help either. Any ideas why I'm getting an incorrect password message? All my other devices work fine with wifi. This seems rather strange (and annoying).
