Hi,Nothing has changed with my Cox modem or set up. But recently my Netgear router has begun losing connection. The 2.4 and 5g lights on the router will go out and devices can't connect to it. I will have to unplug power to the router, or turn it off to regain connection, only to have the same thing happen again, maybe several hours later or a day later. Of course my support and hardware warranty expired expired in June of 2021. The router firmware is up to date. Not sure if should pay Netgear for support to troubleshoot. (I firmly don not believe in this business model to charge for assistance, especially since I paid good money for this router) Or should I just move on? Thanks for any help.Earl

Thank you for the reply. Let me say first, I am no expert in this area. I do realize I have a double router. Here is my thinking when I did this set-up, and maybe I was wrong. Internet comes into my house behind my home theater set-up and I needed more ethernet ports than the Cox modem had. So correct me if I'm wrong, but I was faced with a choice of simply getting a switch/port that could handle all the devices I need hardwired, or get a router like the Netgear I have. I choose the router because I have about 5 or 6 additional devices that are wireless. A PC on the second floor of the house, a Roku, a printer, several Alexa's and several phones. If you think the Cox modem can handle all that, then I can do away with the router all together and just get a switch with ethernet ports. Both the routers have a single band, no more 2.4 and 5. But if the Cox can handle it, I'll just go with that. But I was puzzled by the sudden spotty performance of the netgear. Thanks again.

Forgive me if I'm being redundant, but AP mode will disable the wifi functionality and the netgear will just be a switch with ethernet ports? Do you think the Cox panoramic gateway modem/router can handle everything? I have gigablast speed. Of course I don't get 1gb download speeds but it's the best service they have. The Cox modem combines 2.4 and 5g bands so it's just one wireless channel. Is setting the netgear to AP mode easy to do. Again, forgive me as I'm not very technical. Thank you.

What actual firmware number are you on? Did you try a factory reset and reinstall? or try downgrading the firmware a version (in case its an upgrade that caused the issues) Do wired devices drop or just wireless? What modem/gateway is it connected to?

Cox modem is :Panoramic WIFI GatewayBrand: TECHNICOLORModel: CGM4331COM As I said, firmware is up to date:v1.0.12.120 according to the phone app. A Sony TV and a DIRECTV box are hardwired. There are various phones and Roku's, and a printer that is wireless. I have not done a factory reset, not sure how to do that. Thanks

First off, you're in a double nat as that modem is a modem/router combo device. A double nat happens when you cascade more than 1 router. https://kb.netgear.com/30186/What-is-Double-NATFixes? There’s 3 options but only use 1. 1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions. 2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features. https://kb.netgear.com/26765/Which-features-are-disabled-on-my-NETGEAR-router-when-it-is-set-to-AP-Mode
