I've been using knoppix for a few weeks now, and it works very well, and two days ago i decided to install it to one of my empty hard drive partitions. The internet worked perfectly before and i had no problems with anything, but after i installed it to my hard drive, i can't access the internet thru any program in linux (gaim, firefox, konqueror). I thought i could fix that problem by running the PPPoE configuration to use my sbc yahoo dsl thru my speedstream router with a linksys wireless-g router, but it says i need to be root. I am aware that root has no password, so one must be created in console with sudo passwd root. When i try that, it says i am not a "sudoer". Also, only a few programs, like open office, and konqueror, will work without asking for root permission. I have never had these problems before. Thanks in advance if you have any answers.

BTW, it's not just a faulty or unplugged cable, because windows xp pro has no problem going online.
