I have a G2N Helix 9-DI,G2N Helix 9-SI Mega and a G3N Helix 7-DI Mega all networked through a 5-port hub.They we’re working great until just recently.They will not share waypoints and when I look under my network tab none of them show the other units.i have all recent updates.My question,is there a way to test the 5-port hub to see if it’s still working?is there a way I may have changed some setting causing the units to not recognize each other.TIA
