Hi Re410,
Thanks for trying to help me.
At first, sorry for my bad english as I am a french guy.
My wifi card Linksys WCF12 work with browser (Opera, Netfront)
I can ping my ISP.
I can ping my email ISP in the terminal (#ping pop.mail.yahoo.fr)
I am behind a router/firewall (Maybe the problem

)
but my wife use Wifi too and is behind this router/firewall, and use the same email ISP (but WinXP).
So I don\'t know if there is a blocked port or not.
As wishes, I would like to make the mail LED blink when receive mail.
Cheers,
Richard.
