R8000P Slow Speeds Wifi

I recently upgraded from a R7000 router since the 5ghz band kept going offline after having it work perfectly for a few years. I bought the R8000P since it seemed like the range was better for our size home and it should work for more devices since we have many cameras and smart home devices. The speeds on wifi for all bands are much slower than with the old router. We use to see a consistent 225mbps which is what we pay for with spectrum. Now speeds are about 70 right next to the router and around 20 on the far side of the home. We were getting 200 everywhere with the old router. Is there some settings I should change?  The router is in the exact location as before.
