5G home internet speed after 15-day trial.

I’m a little past day 15 and haven’t seen much difference in speed tests.   My gateway is on band n71 so the most I’ve ever seen is ~170.  You must have been on the faster 2500mhz band n41 to get your 250-400.  Might just be the gateway placement and your seeing slower speeds because it’s connected to n71?
