WP-UT5 RTL8157 Link Speed issue with Synology DS1513+

[rsockanc]

@wisdpi, I just received my WP-UT5 RTL8157 today and have it connected to a Synology DS1513+ running DSM 7.1.1-42962 Update 6 (most current for this older version). The install notes you have at https://www.wisdpi.com/blogs/news/how-to-use-usb-5gbps-ethernet-adapter-wp-ut5-on-synology-dsm work well and I am seeing the interface start and get an IP correctly even after a reboot. The only issue is it seems it's only connecting at 1Gbps. The switch side has a 10GBase-T SFP+ Transceiver that supports 10GBase-T SFP Copper - Support 1.25Gb/2.5Gb/5Gb/10Gb/s data rate and was tested with the WP-UT5 on a Windows pc to run at 5Gbps. On the Synology, file copy test caps at 1Gbps and I cant see what the WP-UT5 is syncing at:
sudo ethtool eth4 | grep Speed

Looking at the logs the driver is already working properly, this speed shows that it's still currently a bug, but it doesn't affect it.
My guess from your situation is that it's the cable to switch part of the problem. Can you provide the switch model, sfp model, and cable performance? Ideally use CAT6A, short distance test CAT5A is fine but requires very good quality

[bb-qq]

Realtek devices require a special command to fix the link speed.
Please check the Readme: https://github.com/bb-qq/r8152/blob/master/ReadMe.txt#L19-L32

Also, from the information in this readme, it appears that the older kernels cannot handle 5gbps links. I am not sure about the actual speed, but I suspect that the display and configuration will not work.

@wisdpi @bb-qq I am struggling with the same behavior on DS920+.
I connected my WP-UT5 RTL8157 to a Synology DS920+ (DSM 7.2.1-69057 Update 5 ; Linux kernel: 4.4.302+) via CAT6 cable.
I'm not able to get a higher speed than 2.5Gbps.
The special command for Realtek devices for 5Gbps speed doesn't work.

My netgear switch GS110EMX recognized it as 5G too.

Is ther any way to activate the 5Gbps.有什么办法可以激活5Gbps吗？

Thank you very much. 非常感谢。

Checking the logs, everything should be completely normal now. How did you conduct the speed test? If you're using read/write tests, make sure your disk array's read/write speed exceeds 2.5 Gbps. It's recommended to first use iperf3 for direct speed testing to ensure there are no issues with the link. Our test results show that the DS920+ with mechanical hard drives struggles to exceed a read/write speed of 2.5 Gbps; you'll need to switch to higher-performance solid-state drives to achieve that.

[horch855]

I think this is not a problem with the mechanical drives. Other users reported over 300 to 400MB/s with mechanical drives in a 4 bay cluster.
It seems that the device could not be advised to 5G as ethhtool only shows 2500basexX/Full.

Is the any way to activate the 5G on the device ?

[bb-qq]

Performance problems have been reported on the Cedarview platform that are suspected to be caused by the USB host controller.
https://github.com/bb-qq/r8152/wiki/Compatibility

Since your model is also Cedarview platform, this may be related. This platform is too old...

[rsockanc]

@bb-qq , I just realized I posted this in general and not in issues, sorry.

[beejj]

did this ever get fixed? I also have same issue on DS1019+ with WAVLINK 5Gbps RTL8157

[rsockanc]

I arrived at the same conclusion as well about the performance of the USB bus. Systems that are older with Cedarview and similar age devices will have performance issues. The best solution is to use 3x 1Gbps lines in a standard connection with no LACP/802.1X and just enabled SMB 3 multi channel on Synology file services. Collecting all four 1 Gbps interfaces will not provide any better performance. In a raid configuration, you should see about 250 MBPs (~ 2.5 Gbps) when connected from a properly enabled Windows 10 or 11 computer with SMB three multi channel enabled which it is by default and a 10 GB nic. You could also attempt to have a client have three 1 gig nice also configured with multi channel and it may work, but only occasionally.
