Hmm...I use Dataone broadband on my Kubuntu linux and have never had any problems. The connection automatically gets turned on at bootup and it stays on......plus the connection is MUCH FASTER in kubuntu linux than in windows 98 (which my bro uses and is so disappointed with its speed).
In Kubuntu the speed often goes upto 70kbps or more!
And in Kubuntu, I didn't even have to install a SINGLE thing...not even the need to pop in that stupid broadband cd or install that pppoe stuff.....All that was needed was my username & password
Last but not the least, even if u DON'T have a hard disk inside ur PC, u can still go online and surf & chat!! Yeah thats possible with linux livecds like knoppix etc.......the pc boots from the CD and u get a working linux OS, as long as the CD is in the cdrom drive. Livecds are perfect for trying out linux and for data recovery if ur pc won't boot.
Try it once
