Orbi AC3000 & Xfinity 1gb Service??

Wanted to close out this thread at least on the initial topic. Here are my conclusions:

Went out to Costco and bought the RBK53. Great deal BTW.  So the router and 2 satellites. Set them up appropriately. So far they have worked as advertised. Speedtest indicates over wireless anywhere in my 3300 sqft home between 400mb and as high as 600mb depending on where I am. Certainly acceptable. It also depends on the wireless device. For example my iPhone X screams as fast as 600mb just about anywhere in the house where as my older Laptops, even at 5ghz run between 400mb-500mb. Again, certainly acceptable.

Here is the stupid thing. When connected to the RBR50 via 1gb ethernet running the Speedtest app on the laptop I consistently get upwards of 850mb to as high as 940mb which means the Orbi is capable of 1gb speeds WAN to LAN. However, if you run the speed test that is built into the router, unlike in my X10 R9000 which is 100% accurate, the speeds reported by the Orbi are absolutely WRONG - in some cases as slow as 200mb or even less. It seems to me that either the Orbi router can't discern the proper location and therefore the proper endpoint server to connect to for speed testing or worse, the speedtest client built into the Orbi is crap, i.e. broken. Bottom line you can't rely on the speedtest built into the Orbi to tell you how fast your WAN to LAN connection really is. Plug in a suitable laptop to the ethernet and try it from there.

I would be interested in feedback from other users to confirm what I have found. Hopefully others can repro this issue. I would love to see this fixed in a future firmware release. What sucks is that I had previously returned TWO Orbi systems, at the request of Netgear support, before purchasing this 3rd setup because I previously thought the speeds were flawed when running on my 1gb Xfinity service.

Thanks for reading!

My Setup:  Xfinity 1gb Service, Netgear CM1000 32x8 Modem, Orbi RBK53 System
