CRS309-1G-8S Upload speed bouncing between 100 and 900mbps

Sun Jan 03, 2021 3:45 am

I just bought a CRS309-1G-8S+IN. I have my Gigabit LAN attached through the Gigabit port and any time I do a file transfer to a PC on my LAN the speed is bouncing between 100 and 900mbps giving me less than half gigabit speed. Downloading seems to work fine. I have tried DAC and Fiber cables to the Mikrotik switch. I changed from RouterOS to SwitchOS and tried a few settings but nothing works. Link status says Link Paused which is odd. Disabling flow control changes link status from Paused to On but issue remains. I also updated to the latest firmware. I have also tried connecting to my LAN on a different port with an RJ45 transceiver and same problem. I have also tried two different 10G NICs. Removing the Mikrotik switch solves the problem and so does replacing it with a QNAP switch.
Any idea how to fix this problem? Please help
