Just updated to firmware RUTX_R_00.02.05.1 on my RUTX09.
Now Data connection shows as disconnected allthough I´m, connected and got public WAN IP.
Router is set to passthrough mode. Everything is working fine, so i guess it´s a GUI bug.
If I send a get status SMS it also shows as disconnected and reports no WAN IP. But i certainly have a WAN ip.
