BGW320 Ethernet Port Speed Breakdown

Description of setup:

AT&T Fiber (1gb) customer here. I'm running ethernet from the BGW320 to other parts of the house. On the other end, I have some devices connected directly to ethernet. In other cases, I have a wifi router (for example in large playroom that may have a few devices)

Description of problem:

Any device that is connected to ethernet is having speed issues. This morning, the wifi router connected to ethernet was putting off download speeds of almost 400mbps. An hour later, that same device was getting less 5mbps. No other devices were using bandwidth.

Comments:

Because there are times that download speeds are lightning fast, I know that the ethernet/switch is fine. I also know that the device network settings must be fine (otherwise, I'd assume you'd never get those speeds). It feels like there is some sort of throttling, or something that prevents it from sustaining those speeds.

Has anyone seen the same issue and had success resolving? I have ensured that all of the ethernet ports are set to Auto as some other posts suggested.

For the record, I had previously gone out of the router using the 5g ethernet port. To try to eliminate potential issues, I moved the output to another ethernet port (yellow). So far, I've been able to maintain downstream (via ethernet) speeds. Potentially that was the root of the issue, but thought I'd drop that here in the context of the topic.

What speed package are you on?

Yeah, we've seen a number of odd issues crop up when using the 5Gbps port on the BGW320. What's interesting is that people who actually have the "hyper-gig" speed packages and equipment capable of >1Gbps connected to that port don't seem to have any issues.  Maybe that's just because they're such a small number of data points, hard to say.

1gb package. I will say ever since moving the outbound ethernet cable from the 5g port to another I've maintained all downstream speeds. Fingers crossed, but so far I think that may have resolved the issue.

I would expect to see wired speeds be in the 900+ range. Do you get that if you wire to the BGW320?  If not,  go to http://192.168.1.254 and go to Diagnostics, then Speed Test then click the Run speed test button, what results do you get?

See below. This is on a device which is connected via wifi on a downstream wifi router that is sourced via ethernet off of a yellow port on the BGW320. Good right?

Yep!  FWIW, that test isn't dependent on which device you use or how it's connected.  It just tells the gateway to run a test directly to the AT&T server, so it's it's a good baseline to make sure that the fiber connection is working correctly.

If you have a Windows computer with Ethernet capability get the Ookla Speedtest App from the Microsoft Store and run it on a connection wired to the BGW and the other router.  You should see similar results unless there's some sort of other issue like bum cable or software on the machine or other router that limits throughput.
