AT&T Throttling Help

Hello. Do you have a BGW320 gateway there and testing with Ethernet connection to port 1?  If yes, move to port 2, use a single computer for testing and confirm speeds two ways.  First with the internal test in the gateway accessed via 192.168.1.254, and second via speedtest.net.  Both results should track.  

Greetings. I do have a BGW320. I get the same issue with both ports. The actual gateway receives full gigabit speeds and I receive full download/upload when running speed tests. This only occurs when I attempt to download large files or utilize streaming services and clears up when I enable a VPN.

Do you have AT&T Internet Security turned on?

No. I do not have it enabled.

Hello @MagnusXL,
Thank you for reaching out to us! Let's work on a fix and find out what's causing this!

We understand the gravity of your concern, and you’re experiencing slow download speeds on your wired connection. Here are some steps you can take to try and resolve the issue:

1 - Update your network adapter drivers: Outdated drivers can cause issues with your network connection. You can update your drivers by visiting the manufacturer’s website and downloading the latest version.
2 - Optimize your network adapter properties: You can optimize your network adapter properties by disabling power saving features and adjusting other settings. 
3 - Use TCP Optimizer: TCP Optimizer is a free tool that can help optimize your internet connection. 
4 - Flush and renew DNS settings: You can flush and renew your DNS settings by running command prompt commands. 
5 - Use a different DNS server: You can use a different DNS server to improve your internet connection.
6 - Check your Ethernet cable: Make sure your Ethernet cable is in good condition and is not damaged. A damaged cable can cause issues with your internet connection.
 7 - Upgrade your Ethernet cable: If your Ethernet cable is old or outdated, consider upgrading to a newer cable that supports higher speeds.

We hope this information is helpful, and thanks for reaching out to AT&T Community Forums!

This has been a reoccurring issue for a few years. The in-person technicians were unable to resolve the issue or figure out the problem either and any work arounds have so far only yielded results for at-best a couple of hours (also a lot of the issues you've stated wouldn't help as it is temporarily resolved by simply turning on a VPN). But for completion's sake:

1. Network adapter drivers are up to date.

2/3. Settings have been optimized.

4. Flushing and renewing DNS settings sometimes (but not always) resolves the issue, but it always returns within a couple of hours.
5. The issue persists between multiple DNS servers.
6/7. The issue affects 6 different cables. These cables are confirmed to work fine when I connect my device to another network. Three of these cables were purchased as part of this troubleshooting process in the past.

Getting a new gateway won't help; it's been replaced and updated many times and it never resolves the issue. Ever since I was upgraded from the PACE 5268AC to the BGW270 (and later the BGW320) this has been a problem. Replacing the gateways or other devices doesn't help.
