Ok. Lightning recently took out my modem. I replaced it with an arris sb6121. I have a vizio xwr100 wireless router. The problem I am having is that my ps4 will not connect to the Internet (i have tried wired and wireless.) My chromecast connects but says it doesnt have access to the Internet. Our phones and pc work fine. Any help would be greatly appreciated.
Phones and pc work. Ps4 and chromecast do not.
