I'd tried Puppy Linux; I'd agree that Fluppy does better at wifi. I'm using Puppeee on my netbook. Both Fluppy and Puppeee are done by jemimah (if I got the spelling right!)
I'm running CrunchBang as my main distro on my eeepc. Absolutely love the keyboard shortcuts. #! used to be based on Ubuntu. Now it's been switched to Debian!
Bodhi Linux is also a good choice as it uses E17 for the window manager. Based on Lucid LTS.
And not to forget Tiny Core Linux! TCL is the smallest at 10MB (now 30MB with other wifi drivers). Absolutely amazing!
I have all of the above on my eeepc
