I do apologize that you have been having difficulty in setting up your Slingbox M2. There are a few things that could be preventing the setup of your Slingbox M2. The router settings, the Slingplayer app, or the Slingbox itself is defective.
The Slingbox may not be getting a strong Wi-Fi signal. You can also try connecting your Slingbox with an ethernet cable to go around most router settings that may be preventing the setup. Make sure to perform a hard reset on the Slingbox each time you start a setup. The links below will provide the necessary troubleshooting steps you may need.
