DS918+ with UGreen Adapter - speed decline

[mckkev]

I successfully set up the driver and adapter with my 918+ on DSM7.2.1. I have speedtest tracker set up and have been getting almost the full 2.5Gbps speeds up and down for months. Then 1 day it just dropped and now I only get about 2Gbps or less, typically in the 1.5Gbps to 1.9Gbps range.

I don't recall making updates on this day (it was almost 2 months ago, I only noticed this now). I've restarted everything, unplugged the dongle, restarted the NAS, I've verified my connection at the provider box is getting just over 3Gbps. I completely re-installed Speedtest tracker in a new container, I've also tried "MySpeed".

However it doesn't change anything, I just can't reach those speeds any longer, it's consistent, just consistently lower than it use to be. I restarted the router, the gateway (Omada ER707-M2). I haven't changed anything physically. It shows a 2500mbps connection in the control panel. Not sure what else to check, any suggestions?

To isolate where the slowdown is occurring, why not check the throughput between your PC and the 918+? For that, using iperf is highly recommended.
