Fiber Slow speeds to devices.

I'm seeing very slow speeds from the router to my devices, doing speed tests from a PC connected over ethernet shows 2-50Mbps download but 400-500Mbp upload.

I see the same results from multiple PC's over ethernet and wireless alike.

Doing the speed test directly on the router shows 800Mbps download 500Mbps upload.

I've rebooted the router, tried the ATT Home app to diagnose and it shows no issues.

I'm not use a VPN or anything funky, these issues just started happening last week.

I have the same issue.  Here's something strange.  Run a speedtest to Lumen or Lumen 2 using speedtest.net.  You'll have to choose Change Server before running the test and search for one of those locations to test against. I can get good speedtest results to some parts of the country but not others.  This implies to me that the issue is on the AT&T network outside of the house.  I also ran a network test from an Xbox and it got "ok" results.  Not sure what site Xbox checks against but that's what made me try random servers around the country.

Hello D283W, we can assist you with your latency and packet loss concern.

 

We recommend that you read our article on High Latency & Ping to learn what acceptable latency is on the AT&T Network. We'd also like for you to send us a traceroute, so we can see the packet loss. Use the article to learn how to run a traceroute.

 

We'll be awaiting your response.

Look at the logs on your (AT&T) routers/switches.  Obviously, with multiple independent users reporting the same issue, the issue is not internal to our homes.  After a few hours latency and throughput returns to normal.  This is only happening in the evenings.  Rebooting my gateway does not help.  Changing interfaces (wifi vs ethernet) does not help.

And, like clockwork recently, download speeds are slowing to a crawl in the evening.

@D283W   What city are you in?  What speed fiber do you have?

Traceroute "time outs" don't always indicate a problem with that server.  The type of traffic generated by that command is considered very low priority so a server that's doing its normal job will often drop the request if it's busy with that job.  Others are configured to drop those packets regardless of load.

The key is that you eventually get to the destination and get a response.  (BTW, that's not really cnn.com, you're ending up at a CDN called Fastly.)

So let's back up a bit.  When you're seeing these slow download speeds, using a wired computer, go to http://192.168.2.254/cgi-bin/speed.ha and run the Speed Test. 

Then download the Ookla Speedtest app from the Microsoft Store and run that to the suggested server and maybe a couple near the top of the list.

Post the results of all of these tests.

So run the gateway speedtest from this IP (sorry, I gave you a bad IP before and it won't let me edit it for some reason)
