While I don't think the OP is correct in that it isn't possible to win online (since I am doing it)

I disagree with what many of you are saying is the reason why. In my experience, at least in California, 20-40, 30-60, 40-80, and 80-160 are much tougher games than an online game under the 100-200 level. This is an opinion based on my own experience & other people who I know play high limits.

I would guess the OP isn't playing as tight as necessary to beat the on-line game. (also guessing he wouldn't have a problem with aggression.)
