I have a problem connecting to the internet using Ubuntu 12.04
I'm trying to connect to my home router/ap using my Lenovo T530 . Every other device works just fine on the WiFi. Also, my T530 works just fine on all and any other WiFi except mine. It's not a router issue, I've triple checked.
I attached data for both connections. One shows data from "BlackXs", my WiFi that doesn't work. The other screenshot is done on the same device just seconds later, on another WiFi named "arbo" (my brother's connection up in the attic) working just fine.
Can anyone explain or offer a solution?
