So i switched from at&t to comcast. With at&t it was just one wifi router but when i switched I had them use my own separate modem and wifi router. The problem is my PC keeps getting a public IP instead of passing it to the router

Long story short, Arris (modem manufacturer) told me the small switch in between is blocking the ip (or the modem just doesnt have the capability of passing the ip past switch to the router). Any help? I really dont wanna reorganize the network

PS the modem is bridged
 
Solution
Modem -> Router -> ( Switch, PCs) - this is the chain you have to build. With PC connected to the modem, the PC gets the public IP address, and router gets … nothing.
