Ok i'll try explain the best I can and please dont' laugh at my MS paint
Ok so imagine the 2 floors are one up another (while the kitchen floor is ontop)
The Red line means (if the word is good in english) a Firewall : Aka a special wall that separate two houses for sound and all that stuff.
Also I have this house since 2013, but started experiencing the problem about 2-3 months ago. (I do not know what's in the wall or between the 2 floors)
Anyway let's try to explain.
My ISP Modem + Router are in the Office room. Internet works everywhere in the house. My problem is my 3ds who randomly disconnect but only in the Living room.
Any room where i'm in I can do internet on my 3ds exept the living room where i diconnect each 30sec-15min (random I know).
I also have an Ipad + Iphone and they never lose the internet in the living room.
When I lose connection on my 3ds sometimes when i go to the home menu it says I have no internet then auto reconnect, or sometimes it seems i never lost internet, but still get disconnected from games.
When I do have internet access I have full bars.
My router is a TP-Link N750 and before that I had a Dlink and still had the problem.
I'm just confused at while only my 3ds has the problem (I now have a New 3ds but I had the same problem with my old 3ds XL)
I know it seems vague, but if you have anything to help me would be appreciated
