I got a new modem from my ISP, the HUAWEI HG655D. My desktop runs on windows 7 and is wired, I have internet on that one. But on my laptop I have windows 7 and ubuntu 11.10 (dual-boot). When I connect with windows 7 wireless, I can surf the internet, but with Ubuntu 11.10 (wireless) I CAN see my modem AND I can CONNECT to it, but I have NO internet.... I can't ping my modem and can't surf with chromium/firefox.
But if I use a wired connection with my Ubuntu 11.10 it works, so I don't think it's my modem.
What can I do to fix this?
