Wifi doesn’t connect if I’m upstairs

I’m finding that Wifi connects when I’m in the living room, where the internet router etc is. But if I try to connect upstairs it is a no go. Booting in Windows 7 (dual boot 😀 ) I find that Wifi connects. I find this very confusing and have it since the install. Please help!

Kind regards.

Hope it helps!

Hello guys, just tried to connect internet upstairs and to my surprise it does connect. Don’t know exactly why. Only thing I’ve done recently is input the codes said bij Oli and Installed Jupiter and laptop-mode-tools. I really don’t know if this can effect my internet but it’s the only thing I can think of.
Thanks for all the help, really appreciate it 🙂

PS If someone thinks it might be helpful for others I would like to help find a ‘real’ solution to this problem. Just post down what I need to post here and I will try my best to help.

grep “Sensitivity” -B2 Also doesn’t bring anything up

Found one curious thing: It does connect upstairs but only close to my door. Everywhere else in my room is a no go, while windows does connect.

Answer

You can generally see more of your neighbor’s routers from upstairs. You might need to select a more disused channel.
