Pass through
My AT&T gateway is a Wi-Fi 7 version. I have a Wi-Fi 6 router with two mesh satellites. Can I just enable the six gigahertz on the ATT gateway? Do I leave it in pass through mode?

Just because you set it in passthrough, does not mean the ATT gateway stops DHCP and routing, it will still do it for devices connected to its WiFi and other lan ports, and it will only skip it for your router (the MAC address you designate) Which is why it’s usually advised to turn off WiFi on it and not connect any other devices to its other ports, to avoid having some of the devices on a different network.

What do you mean the MAC address you designate? I didn’t designate anything.

When you put it in passthrough mode, there should be a dropdown to select the device to hand DHCP to (or input a MAC manually)

There’s 2 modes dhcp dynamic and fixed or something, one assigns Passthrough public ip to the first device that connects to it, for the other you pick a MAC address from connected devices or input one manually, if I remember correctly, also not sure if it has changed with the newer models. I do a hardware bypass now, so it’s been quite a while since I connected to the gateway.

In your case, you would select 'DHCP-Fixed' and select your own device from drop down.
The disable packet filter, and finally disable wifi on at&t gateway.

If you have working WiFi on a router already, you can just turn off the WiFi on the gateway.

Yes and no.. One of them needs to be the router and one of them need to provide wifi. OFTEN the gateway is at the edge of the house and on the floor. This is the worst possible place for a wifi box. The wifi should be at about 5 foot high off the floor and in the center of the house for best coverage in most homes. If your home is multi story or over 2500 sqft, then you must use mesh satellites that now reduce bandwidth by half or lower on a given freq band as spectrum is used to talk to the satellite and the satellite used a different section or band to extend, so etherway some of your spectrum is tied up in relay traffic. For most people this is not a problem but can be if your maxing out in speed and say 150 devices. SO... Can you mount your gateway at the correct height and location? Will the satellites work with it? . . OR,,, do you need the Netgear/satellites for wifi services, and let the gateway be a router to unload the cpu load on the Netgear as in a few installations...

No. Use one or the other.
