Packet loss under heavy load

I'm getting some weird packet loss. If I run a speedtest from speedtest.net and max out my 1Gb connection, I get packet loss, but only on ipv4. Zero packet loss on ipv6.

If I run a download from Steam, I get a LOT of packet loss on ipv4, and only some on ipv6

If I download a file from somewhere like Backblaze B2 which is all ipv6, zero packet loss anywhere

Has anyone had an issue like this before? Running pfsense, but I've tested directly connected to the 210-700, with the same results

We're here to help keep your internet up to speed, @Bandwagon123!


We suggest you optimize your internet connection, since the speed you get on devices connected to your network can vary. The number of devices you connect to Wi-Fi, how you use them, their age and type, and Wi-Fi signal strength all can affect speed. In terms of how this can impact your service, we suggest making sure your AT&T Gateway is directly plugged into a wall outlet, and not using any type of power strip or surge protector. These can cause power issues to the AT&T Gateway, which can affect the way it connects to the internet.


We also suggest downloading our Smart Home Manager application so that we can run a speed test on your service. The Smart Home Manager's test specifically checks the speed between your AT&T Gateway and the internet, versus other tests which check the overall connection between the device you use and the internet. We'll need to compare the speed you are getting to your AT&T Internet plan to see if it falls out of the acceptable speeds you should be receiving.


Let us know if this helps!

Thanks but none of that helps. Speeds are fine, its packet loss I'm having an issue with. None of this is over WiFI either

This issue is outside my network, thanks

Thank you for letting us know about this, @Bandwagon123.

 
Since this is mainly occurring with ipv4, we suggest running a Traceroute to help determine where the connection is dropping. We suggest doing so from your router to lessen any errors.

 

After you've ran the traceroute, can you share with us the information shown on the different hops, so we can help determine what is occurring?


We hope to hear back from you!

@Bandwagon123 Are you still having the same issue? Any does the packet loss only happen at night? Or is it any time of the day?

I am still having the issue. I entered the private message from AT&T but have not heard a peep

Sometimes its worse than other times, so yes it seems to be dependent on time

I'm 99% sure its a problem on AT&T's network because sometimes pings to AT&T IP's 1 or 2 hops away will be fine, but pings out to the wider internet will get packet loss

I did read a forum thread from someone on a different ISP and the end result was low light levels into the ONT. Tempted to ask AT&T to just come and verify. I really do hate people coming and touching things though, I don't trust they will try and "Fix" the problem and make it worse or cause another problem

Gotcha. I have the 1GB Fiber and I game a lot. My connection is flawless throughout the day. No issues whatsoever. No packet loss, my ping in usually low, and I rarely have skip or lags (I usually play Warzone and MWII). But for some reason, when the clock strikes 8PM EST, I get heavy packet loss in game and high ping. Its like clockwork and  alot of others have reported the same problem on these forums and have gotten nowhere. So would you say that your issue only happens around 8-11pm est? Just curious

Hi, Any updates on it? I just got att fiber 1Gbps and I'm having the exact same issue. If I download anything from steam or even run a speed test it causes up to 50% packet loss outside of my network. It always starts from a random external att ip.
