What am I doing wrong??

I've been a student of the game for about 12 months, read numerous books and lots of internet sites. When I play live small stakes games I do very well. Usually making between 3 to 5 times my buy-in during a 8 hour session.

My question is this: When I play online I seem to really struggle and have lost several times. What adjustments should I be making to play smaller stakes online. I'm not an absolute beginner and feel that I use good strategy in live games, why can't I win online??????
