Hi, I want to set up a mesh network using an Archer AXE75 router and an RE815XE mesh range extender. My question is, can I connect a broadband modem to the RE815XE via its ethernet port and have its internet connection accessible to every other device connected to the mesh network, including via the AXE75 router? Or would that only work if the modem were connected to the WAN port on the AXE75 itself?
