Hello, this is Martín, Tech Support Engineer for Teltonika Networks.
If I understand correctly, what you are trying to do here is to use a RUTX11 to connect to a Wi-Fi network, and then providing Wi-Fi access trough a hotspot, as if it was a Wi-Fi repeater, right?
Also, I could not find any attachments to your question, so we are going to need more information in order to solve the issue you are experiencing.
Best regards.
