Since I've been running into quite some issues with the 5Gbe model (bb-qq/aqc111#48), I decided to do some testing with the 2.5Gbe devices. Here's the results.
Notes
Additional comments I did a few file transfer tests. The transfer went quite okay at around 150+ megabytes per second. However after a few second I could hear my NAS starting to have a lot of disk activity (and then also slow the transfer down) which is presumably because it only has like 100gb of free space. So I'm most likely running into disk fragmentation issues here.

Model(platform): DS1019+ (apollolake) Maximum Throughput: e.g. 2.48 Gbps @ MTU 9000 in iperf3 Connection to PC (Intel i225) thru EDIMAX GS-1005BE switch iperf from SynoCli Monitor Tools package from SynoCommunity P.S. Works fine when connected to back USB port, device restarts every few seconds in front USB port (probably power issue). |
Special Testing
No switch used, just direct connect. Bought 2 of the same usb NIC for each end. Also used a 90º angle USB 3.0 adapter for the NIC plugged into the front USB port of the Synology.

Edit for 2.15.0-5 and DSM 7.1Under DSM 7.1-42661 Update 2, the device loses connection after some time (#230) and requires a reboot. DSM 7.0Model(platform): DS1621+ (v1000) Connected to the front port via USB-C to USB-A adaptor. iperf3: |

|
Model(platform): DS418j (rtd1296) Communication with the NAS works over http, SMB etc, one can navigate the folders etc. however if one tries to copy files from the NAS to the PC then immediately the communication drops. I know this because I was pinging the NAS indefinitely and it only stopped responding immediately when I started copying a 4GB large file |

Network backbone consists of:
Maximum Throughput: 2.46 Gbps @ MTU 9000 in iperf3 from NAS-to-NAS (DS718+ (2) client to DS718+ (1) server); both DS718+ NASs directly connected via front USB port (for convenience) to same TRENDnet TEG-S380 switch. |

Model(platform): RS1221+ (V1000) Would've used the driver v 2.15.0-7, but it didn't have a package for V1000 at the time of writing. Update: Stable, except when I install the VM Manager package, the network interface goes down, and only goes back up after a reboot. |

Model(platform): Installed via the instructions, did need to complete a reboot. Front USB only, not detected in the rear USB ports of the DS416 (also noted elsewhere by others). Performance is not as high as some of the others I have seen here, but the MTU is low and the device is old with low RAM, only 1GB of DDR3. Setting MTU to 9000 in the GUI results in an error and it will drop to 8000 MTU. Test conditions and devices:
Comsol CMGB25 reports itself to macOS as such: DS416> CMGB25> Cat7 1m> GWN7700M Switch> Cat5e 10m> CMGB25> MBP There is an issue with the Realtek driver used in macOS that prevents MTU from being set above 1500, which is a huge pain and nobody involved seems interested in fixing it. The Realtek driver provided by Realtek does not run under Apple Silicon (needs to be updated to Apple DriverKit) - the default Apple driver works... but only at 1500 MTU. Have not run the test on the PC at this stage which would get around the MTU issue for testing, haven't sorted a 2.5GBE NIC for it. When running the sustained test, room was approx. 27ºc / 80ºF~ (coming into Summer in Australia). Thanks for your work on this, while my results are way under 2.5Gbps, this is a decent performance jump on my old unit and it's very appreciated. |
The device is not plug and play, you need restart the driver service after reconnect the device. It's a little concern if you are away of the NAS box. But the others port can act as backup option. |

In order to give back and share experiences, I wanted to log my speed measurement results before and after installing the adapter. Following is the comparison. The initial or “Before" setup was with dual 1G connections on the NAS DS920+ and on the client (MacOS) with SMB3 multichannel. The new or “After” setup is the 2.5G adapter and the bb-qq r8152 package installed on the Synology DS902+. Test system is a DS920+ running on DSM 7.2.1-69057 Update 3, with 4GB memory and the USB 2.5G Realtek LAN adapter, with CAT-5 cables under the floors connecting all switches and CAT-6 or better from all devices to the switches (CAT-5 are legacy in the house, the short cables between devices and switches are all newly bought so latest standard). (1a) Disk Speed Test Dual 1G, 1GB package size (2a) Disk Speed Test Dual 1G, 4GB package size (3a) File Copy 23.4GB over Dual 1G (4) OpenSpeedTest Report Subjectively speaking, the r8152 bb-qq setup feels even snappier in real-world use than the measurements suggest. |

Can anyone tell me whether two r8152 adapters can be linked using SMB3 multichannel to double the network speeds? In other words, I would install a second 2.5G adapter and bb-qq package on the Synology and add one 2.5G adapter on the MacBook so it’ll also have 2x2.5G. Will that work on the Synology (on the Mac of course it does) and will it double the network speed? |
SMB3 is a tricky solution. I have done a lot of experimentation with variable success. Example: client has 2 2.5 adapters, NAS has a 10GB adapter. Wont work, even the 10Gb has multichannel support client has 2 adapters on switch1, NAS has 2 adapters connected to switch2, switches are interlinked with 10Gb fiber. Result: only 1 channel works. |

Other than enabling jumbo frames across my network devices, client system, and the NAS, no other tuning was done after the install. |

Model(platform): DS216j (Armada38x) I had to reverse the USB C plug in the adapter. I got a speed increase of about 34% compared to what I got with gigabit. But I was hoping for at least doubling the speed (at least 100% increase). |

If you change MTU to 9000, you may see consistently higher throughput. |

Model(platform): DS1520+ (geminilake) Connected via rear USB port. Didn't show up in DSM until I went through some shenanigans (reverse USB-C plug, try front USB port, reboot DSM, stop/start driver, etc.) |

270Mb/s or 270MB/s? 270MB/s would be 2.16Gb/s |
fixed, tired fat fingers got me |
|
Model (platform): DS1515+ (avoton) I did not play with any of the MTU settings. Sub 2.0 Gbits/sec probably is impacted by my USB-C to A adapter and I only had Cat 5e cables available for testing. |

I am using a UGREEN USB C to Ethernet Adapter 2.5G (2023) (RTL8156BG/Type-C) on a DS-920+, and the connection is only working at 1G. I've tried both front and back ports, and stable and latest releases. I move the same adapter to a Mac and it works fine at 2.5G... DSM 7.2. |
|
Having the same problem if you get but I'm having timeouts, disconnects |
|
Thanks for the quick response! I have the one that should be OK: 0bda:8156:3104 00 2.10 480MBit/s 200mA 1IF (Realtek USB 10/100/1G/2.5G LAN 4013000001) But it's only connecting with USB 2.1 / 480MBps. Is it possible that this is due to the USB-C to USB-A converter I'm using? If this model is flakey, maybe I should just return it and get one that is not flakey.... |
Try rotating the adaptor’s USB C plug by 180 degrees and reinserting it into the USB A adaptor. Had that with one of my 2.5G adaptors … |
Indeed, that can be the 'problem' So , returning one Ugreen adapter, and ordered a club3D CAC-1420. |

MTU 9000 should do much better. |

Ok. Thanks. MTU 9000 [ ID] Interval Transfer Bandwidth iperf Done. C:\iperf> |
Sorry if this is the wrong place, but did you have any luck getting it above 1500 MTU under macOS? Have managed 2.1-2.2Gb/s from my NAS over NFS, would love to push the MTU up to get the last 300Mb/s 😄 |
and others
(This issue has the same purpose as the issue in aq1111. Even though the hardware is different, the report will be helpful to you.)
I've decided to start an effort to collect reports of my drivers working and create the compatibility matrix of the drivers. Since DSM7 has been released and many users are updating their drivers to the latest, I figure now is a good time to start.
If you have previously reported it, it would be appreciated if you could write it anew again. We would especially like to know how stable it runs in the latest environment.
IMPORTANT: Before you post a report Unstable/Not working, I would recommend that you create a separate new issue that describes your problem and link to that. I will only reply to the separate issue because comments for troubleshooting this issue would be noise.
