DSM driver for realtek RTL8152/RTL8153/RTL8156 based USB Ethernet adapters

This is a RTL8152/RTL8153/RTL8156 driver package for Synology NASes.

Supported NAS platform

You can download drivers including other platforms from the Release page and determine a proper driver for your model from this page, but you might encounter some issues with unconfirmed platforms.

I very much appreciate if you report whether it works.

NOTE: I recommend using front ports to connect devices because some users reported stability issues when they use rear ports.

Supported RTL8156(2.5Gbps) based devices

Currently I only confirmed products marked "confirmed working". If you got other products and they do not work, please create a issue with its vendor id.

How to install

Preparation

Enable SSH and login your NAS.

Installation

Go to "Package Center"
Press "Manual Install"
Chose a driver package downloaded from the release page.
[DSM7] The installation will fail the first time. After that, run the following command from the SSH terminal: sudo install -m 4755 -o root -D /var/packages/r8152/target/r8152/spk_su /opt/sbin/spk_su
[DSM7] Retry installation. (You don't need above DSM7 specific steps at the next time.)

How to configure

You can configure the IP addresses and MTU of the added NICs from the DSM UI in the same way as the built-in NICs.

Performance test
