Direct Connect to Wi-Fi Router still slow

[DECCOHI]

I have an HP Envy. See sys info below.

My internet service is now 400+ Mb for an up charge.

Last week I can speed test over 400 Mb DL

Now I can barely top 180 Mb

Spectrum was on site for 1 hour.

They changed connectors with all coax cables

I never use Wi-Fi connection for security reasons. 

They checked my Data cable - Passed

We checked Wi-Fi for curiosity - Passed

We changed Wi-Fi Router - No change

I am at a loss for what to do.

Last week it was speed testing over 400 Mb.

Can the computer consistently reach/handle 400+ MB?
