Night Hawk AX6000 8 Stream 2.4 Ghz wifi really slow
Signed up for Xfinity with 600 down, and bought a SB8200 with the Nighthawk, and am experiencing very slow wifi speeds. I already tested the internet speed from the modem, and from an ethernet co...

You will not get anywhere near 600 Mbps on any router on 2.4 Ghz. With 40 MHz enabled expect around 150-160 Mbps with your NON AX WiFi clients as most are 2 antenna devices like laptops/phones. Some laptops may have 3 antennas so maybe around 200 Mbps max for those. With HT20 speeds will be lower like 60-80 Mbps. HT20 on 2.4 Ghz is preferable as if you live in a neighborhood with many routers there will be more interference and resulting inconsistency in connection. The router automatically switches down to HT20 mode if it detects multiple APs nearby with strong enough signals.
With AX based 2 antenna clients 2.4 Ghz clients you may get like 200-240 Mbps max on HT40 and maybe around 120-160 Mbps in HT20 mode. My testing was mostly on a laptop with an Intel AX200 WiFi card. Mobile devices and other laptops may or may not perform as well and my home characteristics and router placement will be different from yours so you may not necessarily see similar speeds.

Also note that depending on distance and obstacles between your client device and router performance can/will vary significantly. Like my home is mostly drywall interior so I get pretty close to peak speeds even 10-15 from router as mentioned in above posts but if you have let’s say more concrete partitions or granite floors or chicken wire mesh for example in the way signals will be significantly lower at similar distances.
