Succes : DS916+ and PLUGABLE 2.5GBPS USB ETHERNET ADAPTER

[Sjekke]

Working with DS916+ and PLUGABLE 2.5GBPS USB ETHERNET ADAPTER
After installation I had to restart the Synology NAS for it to show up.

Synology Version: DSM 6.2.3-25426 Update 2
Driver Version: 2.12.0-3

[Sjekke]

It seems the USB ethernet sometimes stops working for 2 minutes and restarts. Suggestions?

[bb-qq]

• Are you using the front USB port?
• What was the output of dmesg when the problem occurred?

[Sjekke]

Yesterday I performed a factory reset of my ASUS AX11000 router and the Synology didn't stopped anymore since then. It's to early to confirm that this was the issue. I will see what happens in the few next days and keep you informed.

It's a pity you can't make a new package for the Braswell platform with the latest driver.

• What was the output of dmesg when the problem occurred?

I don't use the front port. Is this necessary since it works with the back usb's?

It seems that using the front usb is the solution. Nevertheless what is your opinion if you see my feedback?

[bb-qq]

Some users reported stability issues when they use front ports, so I would have like to confirm that at first.
However, some users also reported performance/stability issues on old platforms caused by USB host controller/driver. If using front ports does not work for you, your issue may be the same one.

Since I use the front port, my adapter is stable for a week now. No drops at all.

• Can you make a new driver with latest version.
• Any idea if your drivers will work on DSM 7.0?

[bb-qq]

Please check the new release and #68.

[Sjekke]

Please check the new release and #68.

Ok I will test them and provide feedback.

[Sjekke]

Please check the new release and #68.

It works ... but ... it was not easy to get it back working.

Before you install the latest driver I advise to 👍

• De-Install old drivers
• Reboot Synology
• Install new drivers
• Reboot Synology

Normally everything should work. I had problems with the DHCP server in my router but finally after using and not using the DHCP server it works.

@Sjekke good to hear. I'm going to try it out on my DS716+ II in a couple of days.

Good luck!

[phantomtypist]

@bb-qq @Sjekke I've verified the latest beta driver (as of writing this) for Braswell is working with the DS716+ II. I used the bottom rear USB port (top was occupied by thumb drive). Been solid for at least two days and I also copied roughly 7TB over the network to it. I am using the CableCreations USB 3.0 to 2.5GbE network adapter that has the Realtek RTL8156 chipset inside it. On the other end I paired it with a FLYPROFiber 10G SFP+ to RJ45 transceiver, which is plugged into a MikroTik CRS305-1G-4S+IN 10GbE switch.

Forgot to mention I'm running DSM 6.2.3-25426 Update 2

Same here. I'm testing with the rear USB ports and till now everything stays stable. Yes!

[phantomtypist]

I have an RS217 I can think I can test, but it'll be a while before I get around to that one.

[Sjekke]

Still working perfect without instability on my DS916+ after 4 days.

[phantomtypist]

I had a blip this morning, but I'm not really sure what caused it. The Synology was unresponsive over the network for about 15 minutes give or take a bit, but came back on its own. It didn't reboot. I guess I'll just wait to see if it happens again.

That's what I experienced with the old drivers.

[phantomtypist]

Kept getting those random network drops with the rear bottom USB 3.0 port. Was happening like once every day or two. Nothing in dmesg about what was happening.

Switched it to the front USB 3.0 port on the DS716+ II. Will see if that fares better.

I don't have network hick-ups. My adapter is connected on the back. I hope 4 you it will work with the front-usb.

[Sjekke]

This can be closed.
My DS916+ is working perfectly with the latest drivers

[bb-qq]

Thank you. I will leave this issue open until I create the wiki to summarize working reports.

[Sjekke]

I installed the latest test driver, so far so good. But when I use the DScam app on my Ipad the NAS stops working. After 5min. the adapter comes available again ... Can I test something?

[bb-qq]

It is unlikely, but the USB port may not be supplying enough power. In that case, you can solve the problem by using a self-powered USB hub with an AC adapter.

In the meanwhile I'm on DSM7 ... and works perfectly with the new SPK DSM7

Thank you for the reply. I close this issue.
