I pay 590.00 a month for 2 homes with 800/30 service. been with comcast since 1994 ish. (TCI mets then)
They are throttling my office (ATT Fiber 1g) since april 2rd 2023 the send speed from my office (Remote desktop, FTP, everthing) is 300-400 kb/sec. It use to be 30-70 MB/sec So 140 times slower. 8+ hours of calls and they can't fix it. I also pay extra for Uncapped. I even changed comcast IPs to prove its not ATT (commercial)
My office can send to anyone neigbors, in USA, canada even spain fast. But not to my home 3 miles from office. $590 a month and I get to work for free dubugging for them.
My conclusion is they have done a IP throttle on my office. And only the engineers know about it and do not tell the IT help desk people. They are unable to see it from their end.
I can get 20MB/sec if I vpn from home to Chicago then connect to the office. Again that proves its a IP block. Never had issues like this in years.
As a 30 year faithful patron I have to dump comcast from 2 locations + other locations over this.
Its like they bite the hands that feed them, I'm not mad just don't know what else I can do. They can't even admit to doing it either.
I would have to move to get my speed back. Its a block only on this account because we have debugged it on other xfinity accounts. Office to them is full speed 800 Mbit. Not 3Mbit which is what i have been getting for the past 3 weeks.
And $590 a month for cable/tv with no caps. Its not like I have bare bones internet but I am getting dial up like speeds in 2023. I had 5 Mbit in the early 1990s and Im worse in 2023 and paying much more.
Engineers at infinity please let the help desk know what you are doing and also admit to do it to to save me hours of having to debug it to prove you are doing it. At least admit to the paying customers what you are doing to save them from doing all the extra hours of phone calls and debugging. Its my dime I don't like to work for free do you?
Note: My internet is fast and fine connecting to everywhere else except my fixed IP office. And no issues until 3 weeks ago and its been 300kb/sec downloading. I can send at the 30Mbit speed to the office only downloads are affected. I can connect to the office from another house with comcast 40 feet from me and get full speed. So my interent will check ok. My neighbors can connect to my office fine too. Just not me anymore. IP traffic shaper is at work by comcast/xfinity

Just so I understand. You're connecting with VPN to work, and got 30-70 MB/sec before over the VPN tunnel, right? Now you're down into the Kb's pulling stuff, but only when you're connected via VPN to the office from your place right?
That doesn't sound like a throttle problem, that sounds like more of a routing problem at your house.
What are you using? Just a PC/Laptop with VPN software (what type? OpenVPN/Cisco AnyConnect, Wireguard,etc), and just an Xfinity gateway, or do you have some other router in the middle? If there is, how is that setup? Gateway in Bridge Mode or double NAT?
A few other things can go on too, especially if your local subnet is stomping on a subnet range on the remote end with a split tunnel. Is the connection itself bouncing up and down all the time and reconnecting? That's another issue. Again, the software is important.

I don't know what's different about your IP. Something is. If you happen to be at the neighbors house, run a traceroute to your office IP address. Then compare it to your house. It's unlikely left over routing rules on a DHCP pool will send you around the planet 8 times, but you never know. It's comcast.
Have you tried logging into your gateway to take a look at the line signals and error logs? Something to look at for sure. Swapping gateways doesn't fix wire/splitter/amp or comcast Plant issues.

What's important? Everything in the doc, but pay particular attention to Power, both upstream/downstream/SNR/Errors both correctable and uncorrectable. Could have wiring/splitter/amp issues getting in the way. Xfinity has to be recycling hardware because they swap it out for their phone app database problems, (nobody can afford to dump hardware like that), so you got a rental, you might just have someone else's problem. If you got line issues, TCP protocol packet fail retransmits or breaks active state connections. UDP is lossy so it just gets dropped (no data). You might have that going on.
Can be upstream from you too out in the street, but you'll see the resulting garbage on your end. You can post the signal table and error logs here if you want. You have to redact the MAC addresses in the error logs or the bot will mark it private and nobody will see it (private information).

On the weak signal side on channel 2. but no errors. What do the other downstream channels look like?
Are you running a splitter for cable boxes, and is there an amplifier somewhere? For a test, it's useful to bypass stuff and just run clean to ONLY the gateway. See if it magically works fine then.

That's fine, and cable distribution isn't what it's cracked up to be in the first place. There are other ways, and I use failover myself due to reliability issues. In the end, since they orphaned my equipment when it is perfectly capable of handing the data transfer because they want to do an up-sell and have a deal going with Motorola. Rather than invest in new DOCSIS equipment, the money is better spent on something else a bit more future poof. But when you describe data transfer in the Kb range, there is something else going on. Nobody sets a Kb "throttle".
Why are you seeing a data transfer at that speed? Your client is bombing out on the connection and averaging speed transfer. It may start out in MB/s, but when the connection dies, it averages the transfer from what it was, to what it is now. If you don't want to debug that part, that's fine.
Fiber is solid -- well, most of the time if you can get it. 4G LTE is plenty fast enough for work, provided there is nothing else dogging a lot of bandwidth at the same time. Powered Cell repeaters work if your cell service is poor, but line-of-site helps and the antenna needs to go as high up as you can get it. Multiple clients at the same time will max your bandwidth, but T-Mobile is $50/month. As far as non-terrestrial goes, the plans are ~$110/unlimited, the equipment costs around $650, but your equipment won't get orphaned in a five year production run (Xfinity calls that "unsupported", buy new junk). Oddly, no "rain fade" with Ka band satellite and even during snowfall which was remarkably unexpected.
Options are there.
