AC3000 Connect to Comcast

[c_lively]

Good evening,

I'm trying to set up my Orbi RBR50 with my current Comcast ISP.  I can set up the Orbi network, but then when I set Orbi to Router mode and enable bridging on Comcast hardware the network drops out.

So, ultimately, I'd like to set it up to run as the router and disable the Comcast wifi.

What steps am I missing?

Thank you

What is the Mfr and model if the ISP modem? 

Be sure that if your transparent bridging the ISP modem that it's passing thru the ISP Public IP address for your account. Check with the ISP or Mfr of the Modem on how to correctly transparent bridge or disable the Gateway feature on the modem. If not, you can use the DMZ feature on the modem for the orbi router or switch the Orbi router from router mode to AP mode, leaving the modem in router mode.

Why not return the rented gateway to Comcast and buy a regular cable modem?

When you set it up, are you rebooting everything?

1. Set Comcast box to bridge mode

2. Set Orbi to Router

3. Power off both

4. Power on the Comcast box and let it fully boot

5. Power on the Orbi.

Good idea to get your own modem. I believe CC supports BYOM.
