So I just upgraded from the older XE75 mesh router system to the new BE63. In trying to keep all my old settings i plugged in the new unit add chose to add to my then current setup. After adding to the old mesh system i then chose to set the new unit as my main router before adding the remaining 2 units. I thought everything was fine until i realized the guest network is not getting internet. The units are connected with ethernet backhaul and no switch in between. They are being used in router mode as well so no isolation option causing issues. I have installed the latest firmware on all the units and tried to reboot them with no luck. Any help is appreciated.
