Low speeds over wifi vs wired Nighthawk AC1900 (R6900P)
I'm having some issues with low speeds via wifi through my Nighthawk AC1900 (R6900P). I think it has been going on for quite some time and I just never realized it. I have gigabit internet with A...

ATT tends to use modem/router combo devices instead of strictly a modem.
It tends to put you in a double nat.
https://kb.netgear.com/30186/What-is-Double-NAT
did you put your att modem in passthrough/modem only mode?
Or put your netgear in AP (access point) mode?
Or put the netgears IP address into the att device's DMZ?
any of those would fix the double nat.
what gateway do you have from att?
Also, another thing you can try is to factory reset the R6900P and during the install, make sure to leave access controls, qos, traffic monitoring, and parental controls disabled.
lastly, don't trust the built in speedtest from the nighthawk app. It rarely picks the best servers.

Hmmm, thanks for your help. I'll have to look into some of this as I'm not familiar with some of it. But tech savvy enough to figure it out I think.
My ATT modem IS a modem/router combo and I never put it in a passthrough/modem only mode. Also never put Netgear router in AP mode or put the IP address in the ATT modem's DMZ.
I guess it seems strange to me that this would matter? The desktop computer is wired to the Netgear router, so why wouldn't it be getting the same speeds as wirelessly connected devices? Granted, I can accept it if the answer is simply "technology is weird sometimes--it's complicated". :)
The ATT gateway says BGW210-700 on it?

You wouldn't think it'd matter but it creates all kinds of issues.
Its why cascading routers isn't recommended.
Try 1 of the options I listed and see how it goes
