Looking for updated light weight linuxs with wifi , network support

[Coincrazy]

Hi

I need to download linux for using Bitcoin clients ..saving keys etc etc [ I have no faith in windows .. and need a fresh boot to be sure of this keylogger thing ]

I have bandwidth limitations, so the 600+ mb ... 800+ mb Ubuntu distros seem too big - 20 hours or so where I am

Are there any updated light weight ..say 100mb ... 150 mb linux distros that support wifi or even wired networks ?

I have tried Damm small Linux, Core linux etc and they aren't supporting networking


TIA
regards
