Slow Wireless Connections - Time Warner Internet

This question is about "Slow Wireless Connections", with Time Warner Cable internet and apps. Hello...I have the 200 mbps Internet package. I have my own modem and wirless router.

Modem: ARRIS SURFboard SB6190 DOCSIS 3.0 Cable Modem
Router: NETGEAR Nighthawk AC1900 Dual Band Wi-Fi Gigabit Router (R7000)

When I test my wireless connection at, I usually fall anywhere between 60 mbps and 75 mbps download speed.

When I plug directly into the router, using a cat5e cable, I get speeds anywhere from 220 mbps to 235 mbps download.

I'm trying to figure out why my wireless speeds are so low. Any ideas?

Thank you for any help, in advance.
