Getting 45 mbps while paying for 1000 mbps - for years!!!
Did a speed check on my computer - apparently it is running at 45 mbps while I am being billed for and paying for 1000 mbps.
How long has this been going on???? I call, apparently the router I am renting from them cannot even handle 1000 mbps. I
need to bring it in and get an upgraded version. Were you ever planning on telling me this? You are in charge of the billing,
equipment and services I receive. I have been paying for 1000 mbps for years. When will I receive a refund for services paid
for but not provided???? My bill has about doubled in two years.

Probably because of the devices you're using is old. I'm paying for 200mbps. My computer on Wi-Fi gets the same speed 45mbps you have, when my computer connects with ethernet cable the speed increased to 80mbps. My 5G phone gets the speed up to 135mbps. They all come from the same gateway.

That's what Xfinity told me. Went to Xfinity yesterday and got the newest router. Hooked it up last night and guess what???
Still getting 47mbps. [Edit: Language] Why am I paying for 1000mbps and only getting a fraction of that? Devices I use are not
that old.

Devil is in the details.
What is 1G bps (bit per second) service? A theoretical throughput calculation based on the number of bonded DOCSIS 3.1 channels all working together pulling data from one or multiple sources at the same time. What is a "speed test"? An unthrottled connection to a server someplace that will run some type of iPerf test tossing fixed size data packets. Does it have anything to do with the real world?
Meh, sort of. Most things you talk to do load balancing, so most web pages aren't going to load any quicker no matter what your service is, unless it's pretty slow service (under 20Mbps). What slows them down are all lookups they all do while they collect the various components that make up the page itself and the scripts they all run. Look at locations that flash by in the bottom of your browser window. Streaming is just loading buffers in chunks, so it's burst traffic. Doesn't really matter how fast that loads, although to watch super high def 8K streams, you will end up burning anywhere from 25GB/hour to as high as 45GB/hour or more depending on the encoding.
When would it matter? If you are pulling something big from an untrottled source, like a DVD from a fast mirror, it will finish faster. If you have a few clients using data at the same time, they can pull up to 1Gbps = 1000mbps = 125MB/s (Mega Byte per second) worth of data at the same time (more or less). So, maybe 4+ TV's watching 4K streams encoded poorly in H.264 perhaps? Usually, you can cut a stream down to 20MB/s and it will look just fine on a really decent TV.
Do that all the time? Most don't. Not even gamers. The data transfer during gaming just isn't all that high. They do when they're downloading the game, but during game play itself, what is important there is latency, and they try to keep the data transfer to a minimum intentionally -- just the data points, and the GPU in the game console draws triangles to fill in the characters.
Back to your point though. 47mbps or 47MB/s? What are you testing with? It's an interesting number. Why? USB 2.0 has a hardware limitation of 480mbps. But that's not really true. That would be 60MB/s if it was. There's driver overhead, and it also depends on what else is hanging of the USB bus. In a laptop, there are a lot of things on a USB controller. Displays sometimes, WiFi, card readers, pointing devices, etc. All in contention. Add some OS and driver overhead and a network controller? Yeah, around 47MB/s with a USB 2.0 adapter on some things. USB 3.0 ports on some, are really on USB 2.0 hubs as well internally. Laptop architecture is important there. There's some tricks like hardware/software off-loading that can help if your OS supports it and you can pick up throughput that way, but it is what it is. Usually, it's good enough.
For a better benchmark, use a PCI or PCIe 2.5Gbps card in desktop, and that orange or red strip port in your Xfinity gateway (also a 2.5Gbps port). The other ones are 1Gbps ports = 1000mbps, but that's not really true either, because a 1Gbps port in the real world is good for around 960-980mbps or around 120-122.5MB/s worth of data transfer after driver/OS overhead.
You can take your OS out of it too, and ditch background tasks hogging resources. Download a memstick image or DVD from ubuntu. Boot live, don't install it and run from memory. Try your benchmark that way.
Same pathetic or similar result? That could happen too. Then start debugging your Xfinity connection. Maybe you've got some signal issues, splitters, connection problems, wiring/connector problems. In that case, I'd start here: https://forums.xfinity.com/conversations/your-home-network/internet-troubleshooting-tips/602dae4ac5375f08cde52ea0
Hope that helps. Good luck!
