yesterday I upgraded the distribution from 10.10 to 11.04 and since then I have some strange problems.
Firstly, my wireless connection didn't work, the computer said, that I'm online, but I couldn't launch a single page with FireFox, skype or run another inet-app. Then I connected my laptop with the inet cable and after a restart I was online.However, today, as I started the laptop I couldn't get connect either with the cable, nor wireless. The strange thing was, that the icon on the left side always tells me, that I'm connected and I could chat with skype, but that was the only inet program working. FireFox always gives me a "problem loading page" error and the system tells me I have connection problems.
Thank you very much for your help!
