Finally the new LTS kernel will provide us a great Realtek support, without any help from them :(

@bb-qq Oups...i probably should have added it to the #345 instead :(
Feel free to close my issue then.

Wavlink USB C to Ethernet Adapter 2.5 Gbps, 2-in-1 USB to 2.5G Ethernet Adapter, USB-C to RJ45 Network Converter

This sub $24 one worked with your driver on my DSM 7.2.1-69057 Update 3, DS224+ following the directions in the readme. Creates a LAN3 network interface. Allows Jumbo frames.

I've ordered another to try it on my DS416j.

@bb-qq How to verify which chip is inside the usb adapter? I have just received two of this and the hardware ids are:

USB\VID_0BDA&PID_8156&REV_3100 (no brand)

USB\VID_0BDA&PID_8156&REV_3104 (UGREEN)

and both should have the RTL8156B. Can anyone share the hardware id string for a device which has RTL8156BG chip?

[WouterJN]

have the same question: I bought the cheapest adapter on AliExpress, and it has a Rev. 3100. Does this mean it has an RTL8156B chipset?

I'm also unclear about the exact differences between the RTL8156, RTL8156B, and RTL8156BG chipsets. Only the RTL8156BG has lower power consumption?

Version 31.04 (Revision 3104) means RTL8156BG!

uni 2.5 Gbps Adapter with USB-A Plug lists RTL8156B in the description, but the unit I received (and others in European Amazon reviews) reports as version 31.04, meaning RTL8156BG:

Looks like manufacturers run out of the old stock B chips by the end of 2024 and many if not most of those adapters are built with BG chip these days. i got 3 of em for testing and all 3 r based on BG based on their HW id and they all staying cool after 20 min transfer test.

reported to be rev 3104 so latest BG chip

and i also got this one

https://www.amazon.ca/dp/B0856V9FDH

and its also 3104 \ BG

Ugreen one https://www.amazon.ca/dp/B0CWV2Q6HJ remains unmatched in build quality and materials used, classy device

How to verify which chip is inside the usb adapter?

There is no easy way to determine the revision of a chip from its VID/PID. You can use the chip revision shown in the log instead.
When you use the RTL8156BG, the following log appears in dmesg:

r8152 2-2:1.0 eth2: chip rev 14

As already commented, you may refer to the Version of the UI as well.
