DSM driver for realtek RTL8152/RTL8153/RTL8156 based USB Ethernet adapters
This is a RTL8152/RTL8153/RTL8156(2.5Gbps or 1.0Gbps) driver package for Synology NASes.
You may also be interested in my another project AQC111U(5Gbps) driver package for Synology NASes.
Supported NAS platform
- DSM 7.x
- apollolake based products
- DS918+ (confirmed working)
You can download drivers including other platforms from the release page and determine a proper driver for your model from knowledge base of Synology, but you might encounter some issues with unconfirmed platforms. If you are using such an unconfirmed models, the Compatibility page may be helpful.
I very much appreciate if you report whether it works. If you have any problems, the Troubleshooting page may help.
NOTE: I recommend using front ports to connect devices because some users reported stability issues when they use rear ports.

How to install
Enable SSH and login your NAS.
- 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.
- Reboot your NAS.
- This procedure is not usually necessary, but many have reported that a reboot was necessary, so please reboot just in case.
Warning: Do not use Safari for this operation.
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.
Option: I recommend setting MTU to 9000 and SMB protocol version to v3 for better performance.
- DS918+ (USB-LAN2500R)
- DSM 6.2
- direct connection with PC (AQN-107: discontinued, but almost equivalent to ASUS XG-C100C)
- native iperf3
- using docker causes high CPU load
