Unfortunately, it's a little tricky troubleshooting wifi unless you can tell me the light code showing on the physical device. As soon as we have that, we should be able to figure out what is going wrong! There is a chance it will reconnect itself as well in the meantime.
As for schedules, as long as it still has power, it will continue to run the last saved schedule. Keep in mind this will not include any weather intelligence, since there is no connection to the cloud.
When you get the chance to get that light code, let me know, and we will get you back online!
