Losing half my speed when using 3rd party router (Netgear RAX 200 AX11000).

Hi, 

I have seen this so often, but can't seem to find a page with an official fix. I have AT&T fiber with 1 gig speeds. When using a 3rd party router connected to my AT&T gateway my speeds get cut in half. Speedtest on gateway through AT&T show 938Mb down/up. Can confirm this on wired PC also. Internet speed going to router (using Netgear app) are roughly 500Mb down/up. It seems to happen to a lot of people. I have tried both router mode and access point mode. Both yield the same results. Can someone please help or point me in the right direction? 

Thank you!

I assume that the AT&T gateway is in pass through mode?

No, it is not in passthrough mode at the moment. Other people have said passthrough mode doesn't make a difference. Still getting the same bad results.

Sounds to me like you may have a double NAT issue then if the gateway and Netgear are both handling the heavy lifting and WiFi duties. I'd setup the gateway in pass through mode and see what happens. The AT&T gateways aren't capable of bridge mode (at least they didn't used to be) so pass through is the next best option when you want to use a separate router with your AT&T supplied gateway.
