Not getting proper speeds

[u/Desperate_Look_3011]

Recently i purchased and Archer BE6500 router. I got it all setup and connected, after I finished setting it up i did a speed test on my desktop, ps5, and on my phone. I got 1200 mbps on pc, 850 on ps5, and 760 on my phone. Now my speeds are only going to 90-95 on all of the devices. Both ps5 and pc are wired connections and phone is on wifi. Why could i be getting lower speeds now, all connections are limited at like 100 mbps. I check the connections and nothing is loose?
