Preparation

Enable SSH and login your NAS.

Installation

  1. Go to “Package Center”
  2. Press “Manual Install”
  3. Chose a driver package downloaded from the release page.
  4. [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
  5. [DSM7] Retry installation.
    • You don’t need above DSM7 specific steps at the next time.
  6. 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

 

 

Synology 5Gbe NAS USB Upgrade Guide Step 1

First you need to make sure you have downloaded the correct driver (using the boxes above) for your Synology NAS. When you have done that, head to the Package Centre on your Synology NAS. From the App centre window, go to the top right and select the settings menu.

Synology 5Gbe NAS USB Upgrade Guide Step 2

The initial tab ‘General’ should be visible. From here you need to change the trust level option from ‘Synology Inc’ to ‘Any Publisher’

Synology 5Gbe NAS USB Upgrade Guide Step 3

Next, back in the initial App Centre menu, head up to the top right and select Manual Install

Synology 5Gbe NAS USB Upgrade Guide Step 4

From the Manual Install window, click the browse button and find the driver file you downloaded earlier on your local PC/Mac System.

It should end in ‘.spk’.

Select the file and then click the ‘NEXT BUTTON’ at the bottom

Synology 5Gbe NAS USB Upgrade Guide Step 5

You will know if you have selected an appropriate file for the Synology NAS, as otherwise, the screen will tell you it isn’t here. Otherwise, you will be greeted with driver details and asking you to confirm the installation. Just click Apply.

Synology 5Gbe NAS USB Upgrade Guide Step 6

The installation will be VERY fast and within seconds, you should see a new application/icon is listed. This is the AQC111 Driver (for the Aquantia controller in the adapter and this is what the Synology NAS needs to see the QNAP 5Gbe adapter)

Synology 5Gbe NAS USB Upgrade Guide Step 7

Next, connect the QNAP 5Gbe to USB 3.2 Gen 1 QNA-UC5G1T adapter to your Synology NAS USB port. Note, you DO NOT need to disconnect the existing 1Gbe RJ45 connection, as you will still need to access the NAS to complete the installation.

Synology 5Gbe NAS USB Upgrade Guide Step 8

Open up the Synology Control Panel and option the Network Settings

Synology 5Gbe NAS USB Upgrade Guide Step 9

From here, select the tab at the top for Network Interfaces

Synology 5Gbe NAS USB Upgrade Guide Step 10

Here is the important part. Chances are that the first time you have connected the QNAP QNA-UC5G1T ADAPTER, that the new 5Gbe/5000bps connection is not showing.

This is because the system needs to be reminded of the driver. So, to resolve this, head back into the app centre and find the application.

Synology 5Gbe NAS USB Upgrade Guide Step 11

Underneath the Driver name/icon is a drop-down option for the app. You need to click ‘stop’, then the driver will stop operating.

Then you just need to click ‘run’ and then the driver will start again.

Synology 5Gbe NAS USB Upgrade Guide Step 12

After you have done this, return to the Synology Network Connections and Interfaces (from the Control Panel like before) and then you will see the new 5Gbe connection is present. If you have not connected this connection to a PC/Mac/Switch/etc, it will still be grey BUT it will turn blue as soon as you have connected the 5Gbe to a switch/client device

Synology 5Gbe NAS USB Upgrade Guide – Optional Extras

Remember, that if your system has a system firmware update, reboots or other system-wide change, the adapter may need to be restarted again so that the system can ‘see’ the 5Gbe adapter. Top Read/Write speeds of this connection will depend on the Drives/RAID inside your NAS system, as well as the power of the system in question – but you will easily see speeds of between 200-400MB/s at the very least, several times better than the 1Gbe usually available on the bulk of Diskstaiton NAS systems

Additionally, (still to be fully tested) you can LAG/Port Trunk multiple 5Gbe adapters that you connect to your Synology NAS for greater performance speed (effectively 5Gb + 5Gb = 10Gbe) using the bonding option in the Synology Network Interface menu.

Just remember that you shouldn’t really bond the 5Gbe adapter NIC with your existing 1Gbe as LAG works best when the connections are all the same/even, as otherwise, it can present a massive internal bottleneck. Use the link below to find the QNAP QNA-UC5G1T adapter to buy in your region. Thank you for reading this guide and once again, huge props to BB-QQ on GitHub for adapting these drivers for the community.

  1. Does not work for DS920+ DSM 7.2.1. When I enter “sudo install -m 4755 -o root -D /var/packages/r8152/target/r8152/spk_su /opt/sbin/spk_su” into SSH, I get error: “cannot stat ‘/var/packages/r8152/target/r8152/spk_su’: No such file or directory”. Any suggestions?

  2. I have a DS918+ with one 3.0 port at the rear and one at the front. I run my UPS usb cable into the rear and use the front port for backups. Could you make this work with a hub or something to run but the 2.5GbE adapter and the UPS cable into the one rear port?

  3. Can I get 2.5gbps USB network dongle to function on a relatively new DS224+ so I can hook it to my 2.5gbps switch? (I have 2 Linux PCs, and soon a 3rd, connected to the switch @ 2.5, primarily for rsync backups of backups). I saw someplace, someone saying that DSM 7.2 blocks these… I hope not. My 224+ is running DSM 7.2.1-69057 Update 3.

  4. Long-term update. I’ve been running 2.5 GBE with a CableCreation adapter ($35 US Amazon) on a DS920+ for about six months now with no unusual behavior, no hangs or reboot required. I keep one 1 GB port set up on a different IP address in case this one ever fails but so far no issues whatsoever and I get reliable 240-250 Mb/s via SMB without jumbo frames.

  5. thank you for your video, I just have question, on GitHub they tell we can configure the Nic, with this two commands : ethtool –set-priv-flags eth2 “Thermal throttling” off // ethtool –set-priv-flags eth2 “Low Power 5G” on…. I ve typed in my terminal but don’t know really if it s ok, could you add and explain this in your video ?? thanks a lot

  6. Thanks for the video, as usual the most informative. Accomplished the procedure on a 1621+ with 2.5Gbe usb adaptor and works like a charm. However, as usual, the speed is limited by the hard drive R/W speed, but surprisingly using SSD cache in read/write mode (even for the Plex server) did boost the transfer speed from 80Mb/s to 140Mb/s over web browser in Windows 11. I also disabled all “jumbo frames” which tends to slow down transfer speed for some reason.

    One problem I cannot get the solution for, Windows 11 doesn’t allow the SMB connection off the bat I did notice in your video that it did on your machine. Sure would be nice if you could provide a quick video on the fix for that because I am surely not the only one.
    On my MAC, SMB transfer is now up to 400Mb/s.

  7. DS920+ I used the TRENDnet TUC-ET5G, TRENDnet TEG-S750 10G switch, Broadcom 57810S PCIe card, and Cat8 ethernet cables. $320 for everything plus a couple hours configuring. Runs rock solid 275 MB/s

  8. Thanks for the video. Apparently the support for 923+ is not there yet from bb-qq. I tried installing r8152-r1000-2.17.1-1_7.2.spk for 2.5gbe twice but failed. If you come across anything, would be greatly appreciated.

    REPLY ON YOUTUBE

  11. i would like to have know the performance of this 5gbe . most files are a minimum of 4gb i think changing the file size to make the benchmark look better is wrong .
    because if on large files you are only getting 150 to 200 its not worth buying the 5gbe Qnap . at 100 pounds . when you can get a 2.5 gbe and it do the same thing

  12. Thanks, I managed to install the driver on a Synology 1813+ configured as SHR+2, with DSM 7.1.1-42962 Update 6. The connection with Trendnet 2.5 shows as 2500Mbps, then installed the volumes from the IP address of the new connector , but the maximum transfer speed is a little less than 1Gbps… Something could be missing?
    Partially it works but if the speed is less than 1 gigabit it doesn’t make sense. ????

  13. I had hoped that enabling link aggregation of the existing dual 1GB NICs on my NAS would double my connection to 2.0GB but I’m learning that it only enable two different computers to talk to the NAS simultaneously at 1GB each. 🙁 Not sure I want to hack in a 2.5 GB USB NIC…. But the video is great if I ever change my mind.

  14. Hello my friend, thank you for your video, I have a Synology DS223 with a ‘Realtek RTD1619B SoC’ processor. Is it possible to connect using this method? I dont see the driver on that web. 🙁

  15. So to upgrade my DS920+ to 5gb . Am i right in thinking i need a 5 gb switch and a 5gb adapter ?
    Also will my asus rt-ax88u work ok with this? or do i need a 5gb port router ?
    This sounds expensive what brand would be most cost effective for this upgrade.

  16. I inadvertently upgraded to DSM ver 7.2 … will this work on that version … oh yea the armada chip used by my nas has 2 7.1 version drivers ??? I don’t know why …thanks

  17. Thanks, you saved me hours of debugging because the original GitHub installation was missing the information that we need to RUN the damn driver package before we can use it. And I feel so stupid that I forgot to do it on my own.

  18. You’d think by now, you’d just be able to hook it up via USB directly without all this faffing about. Got my adapters ordered, hopefully see some improvement ????

  19. Wonderful video. Worked great to get my old DS1513+ that I use for backups working on my 2.5GbE network! Used the Asus USB-C2500 adapter and it worked pretty much just as easily as you showed here.

  20. Noob here. If my network speed is under a gig Is there a point to doing this upgrade? Do I need to put an adapter on my router or mesh system connected to my adapter on the Nas to get those speeds? Thanks
    REPLY ON YOUTUBE

  21. I did it exactly the way you suggested, the new LAN Connection is showing up under Network in DSM shows the full 5000 too, I set the LAN3 to DHCP and here is the problem, the Synology Assistent isn’t finding the new connection, it always shows me one only, the original one, any ideas?
    REPLY ON YOUTUBE

  22. Firstly – thanks for the video. After watching your reviews for some time I have now fully invested in to Synology hardware (both routers, access points and NASes), and I must say that it’s amazing decision. Thanks for that!

    A quick question – does similar method shown in this video is available to add an additional 2.5/5Gbit ethernet to the Synology WRX560 router?
    REPLY ON YOUTUBE

  23. Get QNAP QNA-UC5G1T its Marvell tech inside instead of Realtek, Linux ready and so its plug and play, only 5Gb is with Marvell, don’t get fooled by the 2,5 Version – its realtek and it will fail

  24. PS: @9:42, it is strongly recommend to type “exit” in the command-line to logout the SSH session, not “just” closing the SSH Client software.
    As not all SSH clients will close the active SSH connection when you close the SSH Client.
    Security above all!
