Netgear Nighthawk AC1750 only gives 200 on 300mbps Spectrum internet plan

After installing new ethernet cables: I connected all my gear like this:  Spectrum Modem > Netgear Nighthawk 1750 Wi-Fi router > to iMac my max internet speed is 225 Mbps.  After calling Spectrum customer support and running some tests they suggested I get a new Modem.  So I dropped by the nearest Spectrum and picked up a new modem.  After connecting and resetting the Netgear Wi-Fi router my speeds didn't improve.  So I called Spectrum again, this time they had me plug their modern directly into my iMac, and speeds jumped to 360+ Mbps. So that proved I was getting their advertised "300 Mbps" internet.

 

So what's wrong with my Nighthawk 1750 router and how can I fix?  Thanks in advance

    Don't enable any Access Controls, Armor, Circle or SPC or Traffic Meter. 


    Use Ooklas installable speed test app on your Apple or Windows Ethernet connected PC. 

     

    If this doesn't improve the speeds, may be time for a new router.

    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
