At&T Fiber-Internet 1000 never running fast

Ever since I got the gigabit  Internet from AT&T fiber, I've never gotten really fast speeds. I just dealt with it but I probably won't it much longer. I purposely test it on devices time to time, that can take really high speeds also.  I've been through all the troubleshooting through the years, to no avail.

An Xbox Series S Edition Console can get up to 433 mbps if you had fast enough internet. But as an example, even with my AT&T Fiber-1000 (GigaBit) hooked up via Ethernet as it always is, right this second it's running at:

Download Speed: 72mbps

Upload Speed: 22.26mbps.  SMH. 

I wish someone would fix it.

Though there is no guarantee about getting any minimal speed guaranteed, other than higher than the tier below yours. But if you have up to 1000Mbps and are consistently getting less than 100Mbps, that is abysmal.

What model gateway?

Is your computer wired directly to the Gateway, WiFi, or other devices in between?

Has the Gateway been reset?

If pre-built what is the model of your PC/Laptop, or what network card (Ethernet or WiFi) does it have?

Do all devices experience slow speeds or just certain ones?
