Does OmniNet alert me if one of my WAN connections goes down? 

Yes, OmniWAN can alert on WAN connection drops, and each site can have it's own settings.

How do I change the alerting options? 

After logging in to the Partner Portal, or Dashboard, click on the Gear icon for the Settings of the OmniBridge. 

On the Overview Tab, scroll down to the Reports section. 

Set the Email Alerts option to the email address. 

Then adjust the time for this OmniBridge.  

** For troublesome or poor connections you may want to make the threshold higher.
