REMOVE one network cable between router and NAS.
Use ONLY ONE (1) network cable between router and NAS.
DO NOT use both NAS network ports, select one and use that one only.
RESTART both NAS and router before doing any more speed testing. DO NOT SKIP THIS STEP. DO NOT FAIL TO RESTART THE ROUTER.
SPEED TEST: COPY one big file (more than 1GB) from your computer to the NAS. DO NOT COPY a folder with many small files, only copy ONE LARGE FILE.
Is the NAS doing something else during the speed test? Like synchronizing a new RAID array? Make sure any array on the NAS is already synchronized and healthy before any speed testing.
Post full NAS array configuration, detailed NAS network configuration (screenshot), Router and NAS restart procedures and speed test results here.
