My application uses WiFi interface over RTCS for regular operation and Ethernet for configuration mode. In this mode the application supplies the DHCP server for the configuration computer and the WiFi connection is expected to remain stable.
If the DHCP server is initialized after a TCP connection is established over the WiFi interface, this connection is closed. It takes minutes to renew the connection and it seems to be unstable.
If the DHCP server is initialized during system initialization WiFi connection is stable but the WiFi interface serves as DHCP server.
My questions are:
- Can I limit DHCP server operation to Ethernet only?
- What may be the reason for disturbing the WiFi based TCP connection when the DHCP server is started?
