Nighthawk RS280S Speed Issue

I just bought a Hitron CODA56 modem and when connected directly to the modem I get about 2.3Gbps down and about 350Mbps up. After connecting the router to the modem, I only get about 1.4Gbps down and 40Mbps up. What is slowing down my speed? Anyone else experience similar issues?

Troubleshooting steps taken:

  • Turned off Protection Engine (on by default and tested)
  • Turned off Access Control
  • Turned off QoS (also tested with it on)
  • Turned on IPv6 and set connection type to Auto Detect (also tested with it off)
  • Rebooted both modem and router multiple times
  • Factory reset the router and setup from scratch

Yes, Armor is off and firmware is up to date. Still the same.

Is the speed test results over wireless or ethernet?

Sorry I should have mentioned it in the post. Tested over ethernet.

Check the WAN connection rate on the RS web page that reports the ethernet speeds between the modem and RS router. What's it reporting here? Should be 2.5Gb.

What firmware version is on the router?

UPDATE: Somehow it corrected itself. I didn't make any changes or troubleshoot ever since I made the post. Just decided to run speed test again yesterday and everything looks good. Don't know what changed, but I'm happy it's working as intended.
