RT-AC86U Slow NAS Access

Hello,

I have Synology DS1813 NAS, connected via ethernet to RT-AC86U running on Merlin 384.15, previously on 384.14. Only SMB is switched on my NAS.

If DS1813 is connected directly to my PC, I am getting full 1 Gbps speeds (about 115 MBps read and write).

If DS1813 is connected via RT-AC86U, I can get a maximum of 55 MBps read and 45 MBps write if testing from Win 10 machine, 22 MBps write if testing via Mac....
