Slow Speeds using Cable Creations 2.5G ethernet to USB adapter - DS920+ #232

Recently purchased and installed a cable creations 2.5G ethernet to USB adapter on my DS920+ using the front USB port. Installed the gemini lake drivers listed on the bb-qq release page and everything went smoothly. Synology network page and TP Link switch all show 2.5Gbps connection. But when I run speed tests using iperf or copy files to the NAS, I'm seeing ~1Gbps speeds. Any tips for troubleshooting?

What type is your switch? (See problem with TP Link TL-SG108-M2 here https://github.com/bb-qq/r8152/issues/180#issuecomment-1011055172)

Device is working properly. The two 2.5Gbps devices were on different VLANs and the router is limited to 1Gbps ports. Placing both devices on same VLAN resulted in proper speed.
