user_2ca6li, Hi! Welcome to the XFINITY forums page and thank you for your patience while waiting for a response. You've come to the right place for support. We can help. Are you using an XFINITY modem or a purchased modem with your Netgear wifi extender? If using one of our modems with your router, you will want to put the modem in bridge mode.
