It sounds to me like your Slingbox is not being seen by your wireless network. There are a few things steps you can take to try to resolve this.
- Make sure your Slingbox and computer you are setting up the unit on (or mobile device you are using to set up the Slingbox) are on the same WiFi network.
- Power cycle your router (power it off, wait 20 seconds, power it back on)
- Hard reset your Slingbox M1 (hold reset button on back panel for 30 seconds)
- Move your Slingbox M1 closer to your internet router
Most customers who encounter this issue are able to connect without issue after performing the hard reset of their Slingbox. Here are some additional resources that you might find helpful:
