Recently, I was told that I was suppose to install the suggested updates on Update Manager, so I did. Since I usually ignore the Update Manager, it took a long time to install everything. After I restarted my PC, I notice the Internet connection wasn't working. I tried to remove some of the packages I installed earlier but that didn't work. I also tried to upgrade my computer to Ubuntu 12.04 but they said I couldn't because I don't have Internet access. It's been a day and still no connection to the Internet on my PC. Please help me, if you have any solutions.
