RAX70 strict xbox Nat and low Ps5 speed

[Krometheus]

I'm trying to decide on keeping either my RAX70 or RT88u from asus. I have ATT where I receive 1 GBPS. The issue is my asus router gives me no issues and gives me faster speeds on PS5. And on xbox for some reason it gives me a strict nat type which could be from some setting or software on the router. Any suggestions or help? Or should I just return the netgear and keep the asus one?

You're right in the nat issue. its because most att services use att's own gateway which has an integrated router with it. 

It causes a double nat.

Options?
1. put the att device in passthrough mode. sadly, att devices sometimes struggle with it or have poor implementation

2. put the netgears/asus's ip address into the att gateway's DMZ

3. put the netgear/asus in access point mode and let the att gateway manage the routing functions.

1. I did bridge mode on the router since I'll be using the xbox through that.

2. The asus router doesn't give me any issues whatsoever. But I'll try this with netgear.

3. But if I use access point it disables the routing features I paid for with these routers.

4. Why is it on metgear I'm having the nat issues AND the lower download and upload speeds as compared to asus?

Maybe the asus has an auto-detection setup for double nat. Not sure as I don't have an asus to compare how they handle double nat issues. 

How are you testing speeds? 

Have you tried testing on a hardwired pc/laptop? Xbox/PS5 speed tests aren't reliable as they don't always pick the best server. Even the pc/laptop we usually recommend trying several servers.

Yes I tested on a pc and got 900+ on both upload and download
