Slower speeds on a Windows PC, other devices are fine.

I would normally get between 220-250 download from speed tests on my PC, with the 500 plan. Got the 1G plan and my PC  speed never changed. Using the same Cat6 cable, same port on the modem I can get over 900Mbps on my wifs laptop. My Xbox tests in at high 700 to 800, granted not the same speed test.

 

I made sure the adapter settings where the same for the PC and Laptop. I even bought a network card to try that over the on board LAN. No change.

Pc is connected at 1Gbit, as I said adapter settings are the same as they are on the laptop.

I thought maybe it is something in the BIOS but I could not see anything, I am stumped and frustrated as beyond belief.

Re: Slower speeds on a Windows PC, other devices are fine.

Hey @Dugath,

 

Thank you for your detailed post! I appreciate you taking the time to share all the troubleshooting steps you’ve already attempted. The more details we have about your PC and setup, the better the Community can assist you.

 

There could be a hardware limitation or it may simply be settings that need to be tweaked. Are you running Windows 10?

 

Perhaps @Datalink could help you shed some light on this.

 

We look forward to seeing what we can track down! Smiley Happy

Re: Slower speeds on a Windows PC, other devices are fine.

@Dugath how old is the pc in question?  More specifically, how old is the motherboard?  Fwiw, I use an older motherboard that started with Windows "something" a long time ago and now runs Windows 10.  Yup, it works, but its no speed demon with Windows 10 loaded.  Just for the heck of it you could download the Ubuntu 18.10 demo operating system and boot your pc from a Ubuntu boot DVD or USB stick.  Run a speedtest with that just to see if there's a hardware issue.  Fwiw, running Windows 10 on this pc, I'll see ~350 Mb/s down 32 Mb/s up.  Running the Ubuntu demo, I'll see ~940 Mb/s down 32/33 Mb/s up.  So, I can only surmise that there's so much garbage running on Windows 10, and this pc is so far from its original drivers that I won't see faster performance with Windows 10.  I've read somewhere that Windows 10 has terrible task management as well, so, that might not help either.  Here's the Ubuntu download link:

Re: Slower speeds on a Windows PC, other devices are fine.

I built this computer about 3 years ago.

 

Windows 10

M5A99FX PRO R2.0 Motherboard

Drivver version 10.32.1206.2018 (Realtek)

 

On the suggestion the other day I tried the driver directly from Realteks site. did not help

 

It certainly seems like this computer is being capped around 250ish. Download rate did not change at all when I switched plans, but as shown above I know I am getting the proper rates on other devices, same cable/port on modem. (also tested other ports and cables)

 

Was also suggested to remove Asus AI suite, but I do not have that installed.

Firewall turned off for testing.

Re: Slower speeds on a Windows PC, other devices are fine.

Booted with Ubuntu and I got a 920 download so I guess it is something with Windows 10.. 

 

Maybe I will just install Ubuntu, it would be a real pain to do though.

Re: Slower speeds on a Windows PC, other devices are fine.

@Dugath was the LAN card that you tried an Intel LAN card, and, did you disable the onboard Realtek adapter prior to running any tests?

 

With a three year old motherboard I wouldn't expect any issues, but, we've seen slow data rates with Realteck adapters before.  Its been a while since this has come up in the forum again. 

 

Do you happen to have a router or gigabit switch on hand that you can run between the modem and pc, just to see if that might resolve the issue.  If it does, that really points to some incompatibility between the Hitron modems and Realtek adapters.  Running a router or switch would isolate the Realtek adapter and hopefully allow it to run at full rates, down and up.  

 

In terms of loading Ubuntu, I've lost track of whether or not you can dual boot a linux based operating system with Windows loaded.  There were issues with secure boot which were caused by Microsoft's insistence of using a secure boot up, but, I haven't kept track of it.  Have a look at any of the following search links for dual boot with Ubuntu and Windows 10. 

 

https://www.google.com/search?q=dual+boot+ubuntu+windows+10&rlz=1C1PRFI_enCA774CA774&oq=dual+boot+Ub...

 

Fwiw, I'd load Ubuntu 18.10 and keep it up to date instead of using the long term supported 18.04.  I'd look to run a dual boot instead of wiping out Windows, and if necessary, I'd install a secondary SSD that I could use for Ubuntu if disc space was an issue. 

 

Fwiw, I believe that Ubuntu runs FQ-Codel as its native packet management scheme, so, this may be of some interest.  The latest version of Linux has Cake (Common Applications Kept Enhanced) embedded.  That hasn't been included in Ubuntu builds from what I've seen.  Maybe its running in early builds, but, I don't follow the Ubuntu world to know if it is or isn't.  

 

https://www.bufferbloat.net/projects/codel/wiki/Cake/

 

There's got to be some simple reason for the slow performance under Windows, I just haven't managed to find it yet.  I can see that with older motherboards, but with a recent motherboard, there shouldn't be any excuse.  Fwiw .....

Re: Slower speeds on a Windows PC, other devices are fine.

@Datalink I got this fixed using a reverse of a fix that is usually recommended .

 

The feature in question is known as Window Auto-Tuning. By default, it is set to ‘normal’ mode, which essentially means it is on. In order to disable this feature, a user will need to use the Command Prompt. ( I run it as Administrator)

 

Run the command netsh interface tcp show global

 

That will then show the configuration options currently set. If “Receive Window Auto-Tuning Level” is set to normal, then run the following command to disable it

 

netsh int tcp set global autotuninglevel=disabled

 

I noticed mine was already disabled so I paid this no attention, but I found another site that stated the following to the same article.

 

Microsoft has responded to the advice given here by explaining that the above advice is not going to improve your speed.

 

So I was like, what the heck, its not working right anyways so I ran the command to enable this.

 

netsh int tcp set global autotuninglevel=normal

 

After turning this back on my download speed clocks in over 900Mbps

Re: Slower speeds on a Windows PC, other devices are fine.

Hi,

 

I am using the CODA 4582 with the 500u package and i notice that on a speedtest I'm only getting about 20-50Mbps and the Ethernet port only has the activity light blinking orange, with the link light off. and I'm using the CAT5e that the modem came with i have tried 2 other cables I have laying around with all the same issue. wondering if anyone has had this issue and what the solution was?

Re: Slower speeds on a Windows PC, other devices are fine.

Hey @RavenSilverwolf,

 

Welcome to the Rogers Community Forums and thank you for your first post! Smiley Happy

 

Those are some disappointing speed test results, let's see what we can do to improve those numbers. Have you tested a second wired PC or a smartphone on the 5G to see if the speeds are anywhere closer?

 

First, we'll want to check your signal levels. If you are familiar with logging into your Gateway, can you navigate to the Status section, then the DOCSIS WAN tab? Please paste everything below Downstream Overview here and we can make sure everything looks in specification.

 

If you've never logged in before, you'll need to do the following first:

  1. Open a web browser
  2. In the address bar, type: 192.168.0.1.
  3. Enter Username: cusadmin.
  4. Enter Password: (Either "password" or your current Wi-Fi password)
  5. Click Login.

 

We look forward to your next post!
