JGS524 switch and Nighthawk 7000 router incompatible?

Problem: Looking for assistance identifying why R7000 router will no longer work when connected to the JGS524 switch

 

Change:  I replaced my modem from #1 to #2

  1. Comcast combo modem/router which seems to be an Arris device TG862G/CT
  2.  Arris Surfboard SB6190 

Setup / Purpose:

Like typical homes my ISP enters at ground level and my home is not serviced well with my router in the basement.  I use a JGS524 switch to feed many jacks in the home and have used one of those jacks to connect my R7000 router to optimize the wireless coverage. With this setup I have had great coverage for several years throughout the areas we occupy.

 

Troubleshooting:

  1. Router is upstream of the switch = Wireless and Wired are functioning but then I cannot locate the router where I need it.
  2. Switch is upstream of the router = No internet available

Thanks in advance for any suggestions,

Jeff

Model: R7000|AC1900 Smart WIFI Router, JGS524|24 Port Gigabit Switch

   Nope.  The problem is in your (new) arrangement.

   Replacing a modem+router with a modem typically requires some other
changes, too.

 

> [...] I use a JGS524 switch to feed many jacks in the home [...]

 

   That's fine, _if_ the switch is connected to a LAN port on a NAT
router.  It's a recipe for failure if the switch is connected to a LAN
port on a modem.

   With typical residential Internet service (which provides one
external/public IP address), you'll need to arrange your devices so:

 

      ISP --- modem --- router --- switch

 

   How you arrange your device placement and wiring is in your hands.
If you need two Ethernet cables (or equivalent) running between your
wireless router and your other equipment cluster (modem, switch), then
that's what you need.

 

   Alternatives to actual Ethernet cable exist (Powerline, MoCA), but
they tend to cost more and perform less well.
