I recently got myself a new HP Pavilion dm4-2102eo with a built-in Intel Centrino Wireless-N 1030 WiFi adapter. After messing a bit around with the partitions on the hard drive, I finally got to install the latest version of Ubuntu (12.04), now running a dualboot setup with the pre-installed Windows 7 (using GRUB).
So far everything has been running smoothly. Ubuntu quickly found drivers for almost all of my computer's hardware. That included drivers for the Wireless-N 1030 card -- or so I thought!
After having installed Ubuntu, I connected to my home WLAN (which was visible along with a range of other wireless networks in my neighborhood). I entered my WPA password and connected successfully. I opened up Firefox, typed in gmail.com, hit Enter and... Nothing happened! It kept on loading until it finally gave up and said that the connection could not be established.
I am now back on my Windows partition where the Internet works flawlessly. So does it on my iPhone, my mother's iPad and my brother's MBP. Since a lot of different devices are able to log onto our wireless network, the problem must lie within the Ubuntu installation.
I am confident with Terminal and know how to do some basic operations but I have no clue of where to start here. I have been searching for solutions online but it seems that most people have different setups and need different solutions. I hope that you guys will be able to help me out.
Thank you so much!
Best regards, Sebastian
