NETGEAR C7000v2 using as bridge mode
Dear all, I have read a lot on this forum about the subject that I'm going to describe, but I've not found a solution to my problem. I have a NETGEAR C7000v2 modem/router/wifi and I want to connect a...

Try this, set the C series modem for modem only mode then connect 1 wired PC to the back of the modems LAN ports, Try LAN #1 port. After the mode reboots, check with the PC...does the PC get internet services here at all?

Unfortunately nothing worked.
I did all the steps indicated and I\the router still doesn't get the public address provided by the ISP.
Again, if I connect a laptop to the modem, which is in bridge mode, it immediately gets the IP address and internet access. But the router does not.
I have a back up router (Cisco RV130) and after following the steps and connecting it to the modem the exact same thing happens. V1 is down.
Both routers were working perfectly with another modem and another ISP two weeks ago. I moved to my new location, the new ISP required me to provide a DOCSIS 3.0 modem (I bought the NETGEAR C7000v2) and now neither of both routers can get the ISP's public IP correctly.
I have never had such a hard time with this modem plus router chaining.
I do not know if there is any incompatibility between NETGEAR modem and CISCO router. I confirm that the routers work perfectly because two weeks ago they were working properly.
I don't know what else to do
Thanks for your support

Try leaving the c7000 in router mode and disable its wifi. then setup the cisco's ip address into the netgear's dmz.
I'm not sure why the cisco isn't pulling and ip address with the c7000 in modem only mode but the modem is working fine if other devices are pulling an ip address/working when connected.

Thank you guys for your interest in supporting me.
Here's how it works:
If the Netgear modem is in routing mode and I only connect to its ports the Cisco router... the router connects well with the ISP and has Internet, always disabling WiFi at the modem Netgear.
The Cisco router does not pull an IP when it is in bridge mode which is what it should be.
Should I leave the configuration like this?Will I be able to do port forwarding and triggering in this configuration?
The Netgear message is clear saying that with this configuration there would be a double NAT and that this is not good.The other option is using only the Netgear modem/router (wifi off) and connecting a switch to it to get more ethernet ports and to connect other wired clients.
I'm really lost
Thanks again

Could it be that the ISP has modified the modem's firmware so that the modem (provided by me, not leased from the ISP) cannot be configured in bridge mode working with an external router?
