x710-t2l low throughput when connected to 2.5gbps wan modem

JustAThousand

I have a x710-t2l running FreeBSD 12.1-RELEASE-p18-HBSD

latest firmware and drivers

 

when I connect to 1gbps wan port on my ISP provided Technicolor CGM4331COM (XB7) modem I can get ~940mbps download

 

when I connect to 2.5gbps wan port on the same modem, I can only get ~400-600mbps download

 

this is odd because x710-t2l claims full support for NBASE-T.

 

there is a thread describing the problem in more detail https://forum.netgate.com/topic/162333/intel-x710-issues

 

apparently this is a drivers issue for x710?

1. Exact Driver and Firmware version as well as the link where the packages were downloaded from.

https://downloadcenter.intel.com/product/189463/Intel-Ethernet-Network-Adapter-X710-T2L

firwmare is 8.15 latest

driver is 26.3 latest

 

2. Do you encounter the same issue when connected to 5 or 10gb? 

I cannot test 5gb or 10gb since the modem provided by my ISP only has 2.5GBASE-T or 1000BASE-T ports

3. Is the 2.5gbps known to be working fine before or is this the first time you're trying this out? 

it has never worked, please refer to the thread on netgates forum for people with similar issues. (people say this is a driver issue)

https://forum.netgate.com/topic/162333/intel-x710-issues/

4. Is there any changes prior to the issue?

never worked

5. PBA of the adapter. You may refer to the link below on where to find the PBA number. It consist of 6-3 digit number located at the last part of the serial number. This would help us identify if you are using an Original Equipment Manufacturer(OEM) or retail version of Intel Ethernet Adapter.

Hello JustAThousand,


Please see below update from our engineering team. 


8.15 firmware is a bit outdated and we have 8.30 which is the latest.  

https://downloadcenter.intel.com/download/25797/Non-Volatile-Memory-NVM-Update-Utility-for-Intel-Eth...


With this, we would like to request to update the firmware to its latest version. There was some speed optimization for 2.5G/5G with respect to larger packets in 8.20 FW (also included in 8.3). However, this optimization is only to reach maximum line rate and you may also need to check the modem as this is a consumer level. It could also be the problem with the WAN modem.


Kindly update the firmware as it contains speed optimization however if same issue occurs, you may need to coordinate with the modem manufacturer for further assistance.


Refer to Intel® Ethernet NVM Update Tool: Quick Usage Guide for EFI that can also be downloaded from link above for the instructions. 


Looking forward to your reply. 


Should there be no response from you, I’ll make sure to reach out after 3 business days.
