Gigablast same speeds as 300 Mbps package

A few days ago I signed up for Gigablast, this is DOCSIS not fiber.  I bought a new modem, Motorola MB8600, and have yet to see anything close to 1 Gbps.  Today a service technician came out and using his meter direct into the modem tested my connection at about 950 Mbps.  While he was here, I then plugged my laptop directly into the modem and conducted another speed test from the Cox website.  The speed test was right about 300 Mbps connected to my laptop with a 1000 Mbit NIC and a CAT6 cable.  I get the same results once I pass traffic through my router.

The technician told me it was likely my equipment.  This makes no sense to me as the equipment I tested with was a direct connection to the modem.  I had high hopes for a Gbit connection, however this is quite disappointing and seemingly not worth the difference in the bill if I can't get decent results.

I've seen several other posts very similar to this same situation.  What's going on Cox?

I had a couple a little faster, and some slower, but this is about average.

Hi Heavy_B, are these results based on a device connected directly to the modem with an ethernet cord? If you were testing while connected to a router, please temporarily bypass the router and connect a device directly to your modem with an ethernet cord. Reset the modem and then run another test at www.speedtest.net/. -Becky, Cox Support Forums Moderator

Yes, as I put in my original post it was tested direct to the modem with a CAT6 cord.  No change for several days now, max is about 300 Mbps.

I see that the technician noted an advanced home network setup in the home and reports verifying correct speeds at the modem. Could you try connecting a computer directly and replying back when that is in place so we can check the modem status again?

As I noted in my first post, the speed test I posted was conducted with the only piece of equipment being a laptop connected directly to the modem.

Right now I have the same configuration.  A single laptop connected directly to the modem via ethernet cable.  I just ran this speed test with no other open applications.

Here is my modem info with only a single PC connected to it:

And here's the same connection data after a few hours:  Why so many uncorrected in the 903-927MHz range?

Hi Heavy_B, just for a comparison, are you able to run the speed test using a different device connected to the modem? -Becky, Cox Support Forums Moderator
