My Roam will no longer connect to WiFi. I have tried adding it as a new speaker in the app. The unit is detected and goes through the adding process until you reach the add to WiFi section. I receive a message that is unable to be added to WiFi. I have re enterd the WiFi password and tried a different network. I have split my network to 2.4ghz and 5ghz. I have also tried resetting the roam and router. The problem began after splitting the network. All my other Sonos devices are working fine on the new network.
