After installed driver successfully, the downlaod speed over 2.5G USB NIC lowered to 30MBps, and onboard NIC to 20MBps. Stable speed. Removing USB NIC & driver not helping, onboard NIC still on low speed.
Used to be 100MBps with onboard NIC. Panel link speed displays correct.
What I tried:
Reinstall USB driver.
Stop USB driver.
Remove USB driver.
Use previous version r8152-geminilake-2.15.0-3.spk.
Upgrade DSM to DSM_DS920+_42218.pat.
Change cable from Cat.5e to Cat.6.
Change router port.
Change test PC.
Restart everthing.
Tested Download Station in NAS, also limited to 30MBps.
Tested download from PC over WIFI6 via router on internet after issue happend, got 90MBps.
