Dear helpful people.
I'm new to all this, tried a lot, failed.

 I have a working Archer C7 cabled to my modem, all works fine. i now want to attache my NAS (Qnap) to the network - to be able to acess it of course.
Whatever i do, whatever port i choose it's not showing.

Are there any settings in the Archer Admin and or stuff? I can't acess the QNAp right now, so i guess i can't change things there, yet. :(

Any help (Use the RJ45, put it on the back of Archer on Port X...) would be highly appreciated!!
