What methods can be used to achieve a 1 gigabit download speed?
It seems they might not have set up your modem correctly. This occurred before my upgrade from 75Mbps to 250Mbps, as I wasn't using the recommended modem. I had to contact them to reach the right speed. I opted for a Netgear DOCSIS 3.1 device instead of the Xfinity model.
You need to upgrade to a modern fully certified docsis 3.1 modem. Comcast uploads speed profiles to your modem, many of these modems don't have a proper profile to get the full speed profile. It may have been certified years ago for 800mbps, but in my experience, the profiles don't always work and you get 300-500mbps max. I've seen this with a few older netgear modems.
Here's a full list of recommended modems on Comcast. I recommend the Arris S33, it was rock solid on Comcast when I had it, and didn't run hot:

The CM1000v2 is listed as 949mbps, but perhaps you have the older v1 version which is not listed as compatible.
Personally I stay away from all modern Netgear products, I've had nothing but issues with their equipment due to poor software/firmware. Netgear is not what it used to be.
I use two PCs with Ethernet and both tested at 265/310 mbs. After that, I connected two laptops that have Wi-Fi and also got the same results. My service shows 265/310. I tried three different speed test options. I plan to try new equipment since mine is nearly six years old (quality shouldn't be an issue). Still, contacting Comcast could help. Running tests on their gear would be wise. Thanks for your advice and support.
