Hey guys.I`ve got the extender RFX 9400.I`ve manage to connect to this via RF,but when i press a command on the pronto its either very slow or says that command failed.Is it better to go wi fi rather than RF ? Only when i tried this via a router like the manual says i could not connect to the website to configure the extender.Is the serial extender a better option and would the response be quicker when i press a command.
