I have a unique situation. My verizon quantum setup will come into the house into a closet in the corner of the basement. Thus wifi is not going to be great. I have an ethernet wire from that closet to my upstairs open area. Since all my hardwired ethernet cables come into that downstairs closet, the solution would be to hook an unmanaged gig switch to the ONT and then 1 port of the ONT to the upstairs connection where I would have them place the G3100 router upstairs and hook in all the other ethernets to the switch.. Might this work or does the switch HAVE TO be placed after the G3100... Thanks in advance.. they are coming wednesday but I want to but the switch tomorrow if I can use it.
