Hi. first post here, not even sure if I'm doing this correctly in the correct place, but I have a big problem: I installed xubuntu in my machine. everything went well the first go, and it asked me to update when I accepted it, it crashed. I restarted the pc, and my keyboard had the wrong characters working (it was a portuguese keyboard but it though it was an english keyboard), my internal mouse didn't work, and my wireless connection was gone. Does anyone know how I can fix this? EDIT: I have fixed the mouse and keyboard, but still no wireless connection. it just doesn't detect any networks, and I'm 100% sure I'm in a place with internet.
