My slow speed internet lost wi if connection with devices in the house but high speed devices continued to remain connected after an internet and power outage. I tried reentering WiFi passwords on the slow devices no luck. I logged on to surfboard app and toggled bridge mode. Now all devices connect on to the WiFi signal in the house but are no longer connected to the internet. How do I reset modem/ router to factory settings without bridge mode. Surfboard internet location 192.168.0.1 no longer works.
