As many others have reported, the internet WiFi speed is terrible for the router.
I have Spectrum 1Gbps service. If I direct-connect (hardwire) to the router I can get speeds over 900Mbps, but when I use the WiFi, with the QoS disabled, I still only get in the low 400's.

Seriously?  This is a $280 useless paperweight!  Now I should go to Spectrum to "rent monthly" a 1Gbps router
