TP-LINK Archer C6 only 100Mbps over ethernet

[Only_CORE]

Hey, I upgraded my router to Tp-Link Archer C6 which is supposed to have 1Gbps ethernet ports but when I try to move files from PC to NAS or any other computer on network it goes only at 100Mbps. It even says 100Mbps ports in routers management page (I attached screenshot).

All cables are cat 5e, and PC and NAS have 1Gbps ports so I am not sure where is the problem.

That is odd, have you looked carefully at the cables to be 100% sure they have all 8 wires connected?

 

I have at least one cable claiming Cat5e but when you look at the end it only has four cables connected so is limited to 100Mbit.

Yes, they all have 8 wires. It looks like SW issue but I looked everywhere and nothing.

Are you sure your server and client devices actually have gigabit adapters?
