If it then became the wireless station (Transmitting an SSID on 4G becoming alive), how would the RUT955 know that it was back in our premise as it would have t listen for our CORP network via wireless client mode?
Client(STA) mode scan wifi time to time. Multiwan function switches to available connection by priority. If you add command to shutdown AP when STA(client) mode is connected and otherwise, then it should work as intended.
Are there 2 radios on the RUT955? ie can it operate in client and station mode simultaneously?
There is one radio but it can work in both modes. You can switch one mode on and off without affecting other.
