Adding RBR750 to a Centurylink C3000z modem/roter
BACK OF THE MODEM/ROUTER
My zycel c3000z modem/router is supplied by my ISP (Centurylink). I'm trying to add my RBR750 as the router and wireless component.
Where do I plug in the RBR750 to the zycel to make it take up the router and wifi functions.
Thank you, I really appreciate any help you can give.
Great on the laptop! Macs and the iPad should be able within the WiFi software "Renew" the lease on the connection that should clear out the old set up and grab the latest. Or "forget" the connection and relink to the WiFi. That's what I have to do every so often.
Well at least you got an education?!
Cheers ! 🍻

Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Do you have DSL or Fiber Service? I have the C3000Z with Fiber and the Orbi. With Fiber you can bypass the C3000Z and go directly from the ONT to the RBR. If DSL, do what Furry says. BUT it's not all that much trouble. I'll Help.
Let us know.
Thanks for the quick reply FarmerBob1,
The first step - putting the zycel in bridge mode - is the one giving me trouble. When I go into the Broadband settings on the Zycel there are multiple settng to be done and I don't recognize any as related to bridging. Here are the settings I see-
1. Select the WAN connection type.
2. Select the line mode.
3. Select the transport mode.
4. Set the MTU value.
5. Enter the VLAN parameters.
There are parameters for each selection but it won't let me cut and paste them. I hope that's enougth info.Also I forgpot to mention I have DSL
