I am using my Archer C3200 as an Access Point, like this:

Internet-------wan:mainrouter:lan-------lan:Archer_C3200 ))))) ((((( client devices

[FONT=arial]The wireless side of things works just fine.

However, whereas all the previous TP-LINK routers I ever owned also routed traffic between devices plugged into the LAN ports on the router, the [/FONT]C3200 does not. If I plug in my laptop into a LAN port on the C3200 (with a static IP for simplicity), I cannot ping anything on the network. Plugging in the same laptop to any of the other routers or switches on the network works just fine, so I know that it is the C3200 that is for some reason deciding not to route anything between its own LAN ports. Why is that?

My intent was to replace my older TP-LINK router with the C3200, and that router did not have this problem.

Does anyone know how to fix the C3200 so it starts routing LAN traffic? Is there a setting that I am missing?
