I'm pretty new to Linux and Ubuntu. I just installed the Lubuntu on my mother's old laptop to replace XP. But after the installation I was unable to connect to wireless network. For at least a week I've been hunting this forum and google for solutions but nothing seems to work. It works pretty well when wired to my router. Also when I do updates or installations of b43 whenever I have to restart or shut down it stays on a black screen or hangs on the Lubuntu logo with the dots. I usually have press the power button to shut it off fully. So I'm not even sure if the updates gets processed. Idk what to do I'm so lost right now. I will be grateful if someone can give me a solution. I would like to my moms laptop to be working as soon as possible(its a delayed mother's day gift)
