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. 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.

Supported AQC111U(5.0Gbps) based devices

Currently I only confirmed QNAP QNA-UC5G1T works. If you got other products and they do not work, please create a issue with its vendor id.

QNAP QNA-UC5G1T (Type-A, confirmed working)
TRENDnet TUC-ET5G (Type-C)
SABRENT NT-SS5G (Type-C/Type-A confirmed working by users)
StarTech.com US5GA30 (Type-A confirmed working by users)

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/aqc111/target/aqc111/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.

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.

Private flags

This driver support additional options.

Disable thermal throttling
- Link speed is configured to 100Base when the internal chip overheats automatically by default. This option disables that behavior.
- ethtool --set-priv-flags eth2 "Thermal throttling" off
Enable Low Power 5G
- Entering to low heat generation mode at the expense of throughput. This option should be enabled when thermal throttling is disabled.
- ethtool --set-priv-flags eth2 "Low Power 5G" on

Performance test

Environment

DS918+ (QNAP QNA-UC5G1T)
direct connection with PC (AQN-107)
native iperf3
- using docker causes high CPU load
enable jumbo-frame(9k)
