If you get the smart home manager app from ATT it has a speed test that tests both ISP to your modem and then your device speed using Ookla.
Here’s a flow chart depending on what happens:
If the speed to the modem is bad, that’s att’s problem and they’ll send somebody out.
If the speed to the modem is correct (at least 950mbps) then:
If the speed to your device is bad (like above, so it is) try on other devices. If the speed is bad for those as well, then that’s probably on ATT and they’ll send somebody out.*
If the speed to other devices is fine (“fine” is really subjective, don’t expect a full gig over wifi. 500 is normal for download but it should be the same for upload, probably higher actually) then that’s on you. Something is wrong with the configuration on your device.
I say probably on ATT because it could also be something obscure such as wifi congestion from other routers but stuff like that is less likely.
