Question Not getting right speeds with Gigablast through Cox

Hi, I currently have Cox cable and I recently switched to Gigablast. I am getting 105 Mbps download speed on my computer. The computer is a Lenovo Ideacentre 310S-08ASR. I bought it two weeks ago because they said my laptop can't handle the speeds I was supposed to be getting. So, I bought a new one. I checked and my ethernet adapter is a Realtek PCIe GbE Family Controller and it can handle up to 1 Gbps. I am hard-wired in to my combination modem router from Cox, the "Panoramic Wi-Fi" one that Cox provides, which is a Technicolor CGM 4141 model. I am using Cat6 cable from the router to my ethernet card and there are no other hardwired connections on the network. I have had Cox out four times so far and they replaced the lines that go from their node to the street as well as from the street to my house because of "interference in the line". I got my speeds verified using Cox's own speed test which is powered by Ookla, the same people who own speedtest.net. When their techs come out, they can get a gig using their machine connected directly to my modem but I can't using the same cat6 cable. The computer also has 32 GB of ram to help speed everything up. I have updated all my network adapters and drivers. What am I missing here? I am literally going out of my mind. Any help would be a welcome relief...

This test really needs to be done while the Cox tech is right there.
He gets gigabit speed on his equipment with your connection...you don't.

Then you can ask him..."Why?"
I have. What I get from them is "Huh. There's nothing we can do about that. It must be your computer."
 
I would have gotten the specs on the techs laptop he tested with.

The machine you list is a very inexpensive model, there are people on this forum that pay more for a router.

Lenovo was a company that surprised me when I found models they put 100mbps ethernet ports in for no real good technical reason. The actual chipset they were using could have run gigabit ethernet but they choose for some reason to not put the port on the machine. It is only pennies different in cost.

The model you have has gigabit ethernet but I see no models that will take 32GB of ram so I am not sure which model you have. They have a bunch with the same part number.

It maybe that machine is just too slow to keep up with a gigabit connection. Open the resource monitor and watch the numbers. I suspect you are maxing out a cpu. Speedtest is not multicore.

I see people complaining in the reviews this machine is slow. It maybe more than just a network thing.

Maybe take your machine over to someone else house that gets good speed and see if it runs any different.



The only other thing would be if the cable has issues with that particular machine. It is not real common problem but it only takes a tiny difference in alignment of the pins to cause trouble. A new cable is pretty cheap to try.

It has AMD A-9-9425 Radeon R5, 5 Compute Cores 2C+3G 3.10 Ghz processor. That seems pretty fast to me. It didn't come with the 32GB of RAM. I installed them myself when the computer was dragging.
