R7500 r47168 trunk version slow LAN connection

[Speedy1205]

I`m using the r47168 trunk version and having issue with wired connected server I have. When I download some from the server to a wireless client I get a speed of 16 MB/s. When I try to upload some to the wired connected Server the speed is just 1 MB/s which is horrible slow. Tried with different Router which works fine. So there is still some wrong with the Port configuration ? The WAN connection is working fine where I get around 5 MB/s (limit ISP).
