It might just be your laptop thats the problem. We've seen several cases like this where the laptop just doesn't handle the higher data rates. We had a laptop that wouldn't go above 200 Mb/s on wifi or running thru a gigabit to USB-3 adapter. That died and the current laptop does at least 600 Mb/s on wifi but only runs about 50 to 60 Mb/s thru the same gigabit to USB-3 adapter. I haven't tried a gigabit to USB Type C connector, its on my list of things to do. The current laptop is an Asus, running Windows 10. We have a gaming laptop in the house as well that does at least 800+ Mb/s via ethernet, its been a while since I've tested it. So, not all laptops are equal, in terms of their data rate capability.
I am totally unable to get my speeds over 500Mb on a 1Gb uplink - I did follow the many suggestions here in the thread and wondering what I can do other than to call a tech out. So I did setup the modem with a Dell Latitude 7420 with 1GB uplink on a CAT6 cable into port 1. Turned off all wireless, just left the wired running. Max throughput is 504Mb down and 30Mb up.
I have firmware 188.8.131.52T03
Just wondering why the speeds are below expectations.

@aelaan, still running Windows 7 or 8 on that laptop or have you loaded Windows 10? If you have Windows 10 loaded, does Dell have the drivers available for Windows 10?
Have you ever seen this laptop run faster than 500 Mb/s anywhere else?
If the modem is a self install, and you don't have any other computers to check the modem's data rate, you're possibly dealing with two unknowns here, the first is the modem's max rate, and the second is the laptop's max rate. Do you happen to have a colleague or friend who owns a gaming laptop? If so, invite the laptop for a test session, the colleague or friend is optional, but, a bribe in these cases can to a long way. Conversely, do you know anyone who has gigabit service running, confirmed to run at +900 Mb/s, that can be used to test your laptop?
Your signal levels and signal to noise ratios aren't too bad. The modem is using DOCSIS 3.1 on the Downstream side and DOCSIS 3.0 on the upstream side. The upstream signal levels are higher than normal for this modem when its running DOCSIS 3.1, but, their well within spec. Typically we see somewhere in the range of 30 to 32/33 dBmV for the upstream signal levels.
It is actually my work laptop, I have nothing in my home that runs 1Gb - at work it pushes close to 800Mb on the 1Gb network. It is a newer laptop and runs Windows 10 with the W10 drivers from Dell. I was also pretty pleased to see the numbers to be within the specs from what I could gather from the information here in this forum.
I am not disappointed but I had expected some more from a wired connection on a fairly new laptop - I downloaded some large files and was not disappointed to see like a 15Gb download come in fairly easy. I will ask if they feel it is needed to have a tech come out or if there is anything that can be done without too much hassle.
@aelaan, ok, the laptop runs 800 Mb/s at work, then that's what you should be able to see with your modem. Thats exactly what I wanted to confirm. Call tech support and ask the CSR to:
1. Check the provisioning in the modem and ensure that its set for gigabit service; and
2. Run a signal check on the modem and see if the it passes.
Ensure that the CSR understands that your laptop can run 800 Mb/s, as observed at work, but, the modem isn't delivering that data rate, for whatever reason.
Rogers Speed is very inconsistent. Best day I clocked 1.2 GB and most days below 700MB and then some even less than 400MB while paying for 1GB/50 Service. While in general the 4582 has performed well with minor glitches, service has improved but consistency still is lacking. You may want to also try different tests sites...DSL and Google Fiber speed tests.
@Datalink I am pleased to let you know that I was chatting with a CSR today and while we were chatting she asked me to check my speeds again.... Woahhh!! 953+255 on two systems at the same time. Single I am hitting the 1Gb now on the wire. Of course, they never tell me what they did and looking at the numbers on the modem I see no major differences.
