New Xfinity 1200mbps service with Motorola MB8611 Modem - Only Getting 650mbps in ORbi app on RBR750

[MalShakes]

Xfinity technician visited today and confirmed that he is seeing 1300mbps coming in.

Factory reset since then and still getting the same result. 

2.4ghz set to port 11

5ghz - port 48

20/40mhz coexisitence checked

WMM enabled for 2.4 and 5 ghz with cts/rts set to 2347 on both and preamble set to short

IPv6 disabled

Traffic Meter disabled

Firmware V4.6.3.7_2.0.49

Any suggestions on how to get speed up to gigbit? Thanks in advance!!

There currently is a known problem with the onboard speed test app showing inaccurate speed results. NG is aware of tihs. 

Use a external speedtest app like ooklas installable speed test app on a wired PC. You should see near 900mpbs on the wire. 

Your iphone speeds are to spec for that device.

A couple things. 

1. you won't hit gigabit speeds over wireless. 

2. the built in speedtest isn't accurate over 400-500mbps because it rarely chooses the fastest server. so try hardwiring in a pc/laptop and testing the speeds. 

3. You're posting in the pro-gamer forum (xr300/xr450/xr500/xr700/xr1000) and not the orbi AX forum. If there's issues, you'd have better luck in the proper forum.

Orbi is connected to modem with cat6 cable.

To clarify the speed I am seeing is from the Orbi app, testing speed from router to modem to internet. How do I get this to show the actual speed coming in at the cable, which is 1200+ according to the Xfinity technicians test.

Incidentally testing from my iphone 11 over Wi-Fi shows 650-750mbps download and 40+ upload.

Thanks!
