Intel I225-V 200mbit limit

Hello dear Community,

 

As the title suggests, I have a problem with the Intel I225-V ethernet controller on my Asus ROG Strix B550-F Gaming, or more specifically, it's windows driver.

 

I have run several speedtests over the last week, and never crossed 200Mbit/s on my connection:

I went through a few troubleshooting steps to land at the conclusion that it is most likely an issue with the windows driver:

- I have used a different PC with the same cable --> I had the full speed my ISP allows for (500MBit/s)

- I have used an Ubuntu live boot on the same PC this issue exists on --> Full speed.

 

The CPU (AMD 3950x) load during the tests were between idle (1-5%) and ~15-20%.

 

I have since tried to reinstall the most current driver (1.0.2.14), and install the two previous versions(1.0.2.8 / 1.0.1.4) of the driver that are available for my motherboard:

All to no avail.

I am at a loss and looking for your suggestions what the next steps to alleviate this problem might be.

 

Best,

Hello desert1701,


Thank you for posting in Intel Ethernet Communities. 


Please provide the following information that would help in checking your query.

1. Just to confirm, does the issue occurs on both Ubuntu and Windows OS? 

2. What is the exact Operating System used?

3. Cable type used?

4. Double check the established connection speed in the settings of your system: Network and Internet Settings; View your Network Properties and scroll down to Link speed (Receive/Transmit).

5. When was the issue first encountered? Is it during initial integration? If no, for how long do you have the Asus ROG Strix B550-F Gaming?

6. We'd like to set your expectation that we might have a limited support on this request since you are using an OEM Ethernet controller that's embedded with Asus system. For Original Equipment Manufacturer(OEM) on-board Ethernet controller, it would be best if you can also get in touch with Asus for further support since they have customized drivers and software to enable or alter features on your system. They are in best position where you can seek assistance so you don’t lose features or customizations of the Ethernet controller.

Hi Crisselle,

 

thanks for getting back on this.

 

1. No, the issue only occurs in Windows 10 (current build 19044.1706). In Ubuntu (20.04) the issue does not occur, I have full network speed.

2. see above

3. The Cable is a cat6 flat cable of ~20m. I omitted this above, since the Computer only has the issue in Windows, not in Ubuntu, so I do not see any problems with the cable. I did test the cable with a different device as well and did not have an issue with the DL speed (A Lapotop with Win10). I use the same program to determine the internet speeds on all configurations; Win10 on the machine that has the problem, Ubuntu on that same machine and the Win10 laptop.

4.

5. I can't pinpoint the exact time I started to encounter the issue. I used to run this same configuration on a Gigabit Internet connection and did not encounter the same problems. Although I do think I remember also having truncated speeds, more like 700/800Mbit than gigabit. But that might have been the ISP. I would say the issue is presisting for at least 3-4 months.

 

6. I will open a request with Asus as well, thanks for the suggestion.

 

I'm currently in the process of backing up my data and reinstalling windows to see if that alleviates the problem.

//EDIT: I reinstalled windows. The issue is gone.
