New access point

Our house has concrete walls and for some time the wifi signal has been struggling to reach all parts of the house. It used to be ok and I do not really know why this problem started to happen.

Finally I have bought a new access point and installed a bit of wired LAN section to plug it onto.

Set up in 5 minutes was what it said on the box - more like 2 hours for me and I still don't really understand what I was doing - still it seems to be working so hopefully the problem is solved.
