Latency bounces all over.

I have an extremely fast Netgear Nighthawk CAX30 and the 1.2Gbps package and I get at best 800Mbps and most of the time like 400-500Mbps. This is absolutely ridiculous for the money I have to pay every month. I am hard wired for my PCs so I should be getting the 800Mbps at the very least on the regular. I am pretty sure Xfinity throttles customer's network speed.

The CAX30 is not compatible with Gigabit internet service. Comcast/Xfinity rates it for wired download speeds "Up to 949 Mbps". See https://www.xfinity.com/support/devices. Using devices on Internet speed tiers for which they are not approved tends to produce unexpected results, often speeds well below the ones you are paying for.

@BruceW​ The product itself says it can run 2.7Gbps speed. Why would it not work for 1.2Gbps package?

@BruceW​ even if it get max of 949Mbps then why am I not seeing anywhere near that? I just tested it with nothing connected and I get 747Mbps. I typically don't even get that fast.

Netgear did a lot of exaggerating in the specs for the CAX30. The data sheet at https://www.downloads.netgear.com/files/GDC/CAX30/CAX30_DS.pdf hints at speeds of 10Gbps, but that's a DOCSIS value that does not apply to this gateway. At the bottom of page 3 under the Xfinity/Spectrum/Cox heading it says "Certified with Xfinity with speeds up to 800Mbps", and that's the reality. And the 2.7Gbps speed you mentioned is a bit of a stretch as well: it's a Wifi speed they get by adding the maximum 2.4 GHz Wifi speed to the maximum 5 GHz Wifi speed (page 5).

... even if it get max of 949Mbps then why am I not seeing anywhere near that? ...

AFAIK Comcast/Xfinity has never said how they provision devices operating on speed tiers they're not approved for. All I can tell you is that many customers who tried it have reported that they don't get full speed. There's a tendency to think the device will operate at the maximum speed it is capable of, but that doesn't seem to be the case.

The suggestion is incomplete as it doesn't mention the "All Compatible Devices" link near the bottom of https://www.xfinity.com/support/devices (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2024.09.18%20Full%20List%20of%20Compatible%20Devices.pdf, but this changes from time to time). The PDF contains many devices that the web page once did, but no longer does.

Comcast/Xfinity does a disservice to its customers by not bringing all the 3rd party device information together in one place, including all the requirements for the faster upload speeds introduced over a year ago. It should NOT be necessary to have to consult the Devices page, the All Devices PDF, and a random (and currently unavailable) Reddit page to gather all the information needed to decide which device to use. A $100 billion company can easily afford to do better.
