No option to change the buffer size of I225-V in Windows 11

[MatrixC7]

Hi,

I have encountered a problem with the I225-V losing connection sporadically when I initiate a backup on my Synology NAS. The issue is as same as what is shown in the pictures provided in this reddit link. I am certain that the disconnection is caused by the I225-V because when I use a Wi-Fi adapter, there are no more disconnections.

Fortunately, there are already two links in the forum discussing this issue: Intel i225 Network Adapter Drops Connection When NAS Backs Up PC, Intel I225-V connection issues. These threads suggest increasing the Transmit Buffers and Receive Buffers to 2048 in Adapter Settings as a solution. However, my biggest problem now is that I cannot find an option to change these buffer settings on my PC. I have thoroughly checked all available options under Intel I225-V adapter > Configure > Advanced.

Here is the environment:

Motherboard: MSI Z690 Unify, 2 I-225V adapters

OS: Windows 11 Insider Preview 23506.1000

I225-V Driver Ver: 2.1.3.3

Any advice?

Kind regards,

Fangru Shao

Hi @MatrixC7,

Thank you for posting in Intel Ethernet Communities.

Based on your description and interface, this may seem like an Operating System or Network driver issues.

Kindly provide the following information for us to check on your query:

1) Did you face this problem before install/using the latest OS release: Windows 11 Insider Preview 23506.1000 ?

2) If you boot into safemode with networking <https://www.msi.com/support/technical_details/DT_Boot_OS_Entry#txt02>, do the Transmit Buffers and Receive Buffers appear? 

3) Have you reach out MSI support for driver installation of Intel® Ethernet Controller I225-V? It is because the Intel® Ethernet Controller I225-V is embedded on Original Equipment Manufacturer (OEM) system, it's best to check with the manufacturer as the software drivers linked from Intel page are generic versions, and can be used for general purposes. To avoid any potential installation incompatibilities on OEM system, Intel recommends checking with the OEM and use the software provided via system manufacturer. 

4) You may consider network reset, it should be the last step you try <https://support.microsoft.com/en-us/windows/fix-wi-fi-connection-issues-in-windows-9424a1f7-6a3b-65a6-4d78-7f07eee84d2c>

Please let me know if I can be of any assistance.

Hi BY,

Sorry for the late reply! I have followed your advice and the results are as follows:

1) To be honest as I have just owned my first nas these days I have no idea whether there was such an option to tweak.

2) Safemode wont make it appear.

3) My driver ver before I installed the OEM ver driver is 2.1.3.3 as I have said in the thread, and OEM gives me 1.0.2.14 ver. The Transmit Buffers and Receive Buffers does appear and I could tweak its value to 2048, but I am not able to achieve the results for the 2 threads I have mentioned. With the option of Compression and Encryption on, the problem with the I225-V losing connection sporadically still occurs, though with Compression and Encryption both off it wont appear anymore.

4) Sadly it doesnt work.

Therefore now I compromise to use the Compression and Encryption both off version of Synology ABB to back the data, as it's the only solution I could take.

Kind regards,

Fangru Shao

Hi @MatrixC7,

Please accept my apology for not mentioning it clearly that the Intel® Ethernet Controller I225-V driver may needed to be reinstalled. In this scenario in related to Intel I225-V Network drop connection when NAS back up starts, firmware update for I225-V on Motherboard: MSI Z690 Unify can beneficial.

We're glad that you are able to gain back the transmit & receive buffers options. May I know if you can see other Network adapter (as your desktop should have 2.5G and Gigabit LAN) other than the wifi, virtual or VPN adapter?

Based on the 2 threads, the workaround was turn off Compression & Encryption and the transmit & receive buffers to 2048, after got the help from MSI support on the latest driver and firmware for I225-V.

Hi BY,

I have reinstalled the driver for 2 i225-V network adapters but sadly the situation remains unchanged, though I have changed both transmit & receive buffers options to 2048.

As it has already cost me much time I eventually decided to use the Synology backup without compression and encryption.

Kind regards,

Hi @MatrixC7,

Thank you for your prompt reply.

We glad the driver options has recovered but we also recognise the limitation knowledge to allow Synology backup with compression and encryption. May I suggest if you to reach Synology for better support on its technology?

We sincerely apologize for not knowing more about the Synology backup with an Intel NIC.

Please let me know if I can be of further assistance?

Hi BY,

As I use Wi-Fi to do the backup with compression and encryption, the disconnection won't appear and the Wi-Fi NIC I am using is also from Intel (AX211), I could make sure the problem should not be with Synology but i225-V. Hope there would be a version update of driver fixing the problem.

To add:

 - With compression off, it would lose connection sporadically.

 - With encryption off, there would be an "unknown internal error" and then the backup stops.

Kind regards,

Hi @MatrixC7,

The Intel® Ethernet Controller I225-V is embedded on Original Equipment Manufacturer (OEM) system, it's best to check with the manufacturer as the software drivers linked from Intel page are generic versions, and can be used for general purposes. To avoid any potential installation incompatibilities on OEM system, Intel recommends checking with the OEM and use the software provided via system manufacturer.

The workaround was to disable Compression and Encryption.

Kindly provide the following information for us to check further on your query.

- Do you have other system to perform similar test?

- Was the issue persisted on both of the LAN port of 2.5G?

- Do you have an USB Type C ethernet adapter to test it out?

- Can you please share with us the following from the system:

1. Memory dump after the issue reproduced (see instruction below)

2. Collect event viewer log (see instruction below)

3. What is the link partner (switch/mode,/router) being used (company and model), it might be that the issue related to interoperability with specific devices.

After the above information is collected, our next step will be to collect a driver log during the failure. Instructions on how to do this will be forthcoming.

Memory dump:

https://learn.microsoft.com/en-us/troubleshoot/windows-client/performance/generate-a-kernel-or-complete-crash-dump

- Follow the manually generate memory dump file 

- After restart MEMORY.DMP will be found in C:\Windows\memory.dmp

Event viewer: In event viewer choose Windows Logs > System > Save All Event As and save the file

Looking forward to your response. Thank you.

Hi BY,

I have been outsides these days and wont be able to touch my pc until 26 Aug. I am wondering whether it is possible for you to wait until then. If not then I would just leave everything there.
