Slow speeds through the Router
Netgear CM1150V Cable Modem
Amplifi HD Router (with mesh points)
Xfininty 1GB Service
New Cat6 cables throughout
When I hook the computer directly to the cable modem, the Xfinity Speed Test consistently shows ~750 MB/s download speeds. Move the cables to run though the router (computer to LAN1 port, WAN to cable modem), the max I see on the same test is ~240MB/s. Multiple tests, multiple runs.
Why am I seeing the slow speeds through the router? Something I'm doing wrong?

@Scott-S-0 I have read the not having Hardware NAT on can contribute to this. Here a the steps to make sure Hardware NAT is on.
- Launch the AmpliFi app.
- Select the AmpliFi router icon.
- Under Settings, select the Internet subsection.
- Scroll down to the "Other" subsection and toggle the Hardware NAT to the On position.
- Tap ✓ to save your settings.
- The router will perform a reboot, and Hardware NAT will now be enabled.
Thanks for the quick reply. Unfortunately, I already have Hardware NAT enabled.

@Scott-S-0 Have you tested latency in both setups?

@Scott-S-0 did you find any solution? seems to be almost the same problem as me. But the difference is that when I - for some reason - saves any settings in the router I get full speed for a couple of minutes, then it goes back.
I am all out of ideas..
Hi, Daniel. Yes. After trying everything I could, my solution was to move to the Netgear Orbi Wifi 6.
Unfortunately, that's not much help to you. Sorry.
