slow wired connection vs speed at Residential Gateway


slow wired connection vs speed at Residential Gateway

I have a slow wired connection compared to what the Gateway registers on the speed test. Below is the wired speed test on my computer

  • Download Speed HELP 74.8 Mbps (9350 KB/sec transfer rate)
  • Upload Speed HELP 271.5 Mbps (33937.5 KB/sec transfer rate)
  • Latency HELP 21 ms

This is what the gateway shows:


You are getting 400.311 Mbps speed at your AT&T Residential Gateway which is within range for your subscribed speed package


This doesn't seem right to me

Re: slow wired connection vs speed at Residential Gateway

Hi @evrtlee!

Thanks for reaching out to us. There are different factors that can affect your internet speed. Have you tried wireless connection? If not, please try wireless connection, check the speed and let us know.

We suggest that you Restart your Residential Gateway now and then. You can view this article on How to Optimize your Internet Speed.

You can also get details on How to Optimize your networking experience.

Let us know if this helps!

Re: slow wired connection vs speed at Residential Gateway

I have the same situation. I just started using AT&T fiber, planning to switch from Spectrum.

If I connect to the AT&T on a wireless connection directly to the device, I get the roughly 400MB down and up that fits in with my 300MB plan. 

But, if I connect the same PC, equipped with a gigabit network card, and test my speed over the wired connection, I consistently get less than 100MB down, and about 230MB upload speeds!

And yet, that same device, wired to my Spectrum Internet circuit, gets 180Mb down and 12MB up, which is in line with what my contract with Spectrum offers.

The installer said it has something to do with the limitations of the device I am connecting, in that my equipment is slowing the process down. 

And I'm thinking, then how do I get the 200+ MB upload speeds, but always less than 100MB down? There is no way that a device is going to throttle the speeds down to 1/2 the upload speed!!! That's just dumb.

And, moving the exact same computer from the wired AT&T connection to the wired Spectrum connection and getting the proper speeds my account specifies, seems to demonstrate that the issue is not with my equipment!

Now, I will say that if my connection to the AT&T modem is wireless, like from my I-phone or Windows PC, speedtests consistently show performance above what my plan specifies.

But because of my home's layout, I support wired devices also.

I think it is very strange that the wired connection to an AT&T modem is so dramatically limited compared to a wireless connection.

And AT&T either refuses to take us users seriously on the issue, or does not care about wire connected devices.

But hey, the modem they supply does have the 4 gigabit ports available to connect to!

I suspect this really is something in the Arris BGW210-700.

But personally, I have already put too many hours into trying to figure this out. And the AT&T installer was of no help in resolving this. With others experiencing the same issue, I am concerned that this will not get resolved any time soon.

I did go to the links provided by the tech's response, and the notes for optimizing your network experience suggest that a wired connection is better performing than wireless, which has generally been my personal experience over the years, as I am in the IT business.
