http://www.linuxquestions.org – Hi, I'm a newbie to linux, and been trying to set up a wireless connection for my Acer Travelmate 5530G. These are some of the things I've tried to find out information based on other threads, I've tried some other stuff also, but after 3 hours I started feeling like I need someone's help. I think one thing to start with could be to get the '*-network DISABLED' of the last paragraph to say something else. Also, when I press the "Wi-Fi" -button on top bar, under 'Wireless networks' it says "device not ready" Thanks in advance iipee@ubuntu:~$ sudo ifup wlan0 [sudo] passwor (HowTos)
