Good day to all . Just received a Multiplus II 48-5000-40 GX to install . I thought the previous ones were coming with a little antenna to connect to the top . But anyway, it seems this one does NOT connect to a wifi network UNLESS I add a wifi module ? Does this unit REQUIRE such a wifi module ? Thanks for the update from those who know ! P.S. Came with a "regular / Not GX" manual !
