Right.  This is why I don't want to risk any expensive or interesting tech.  So two things.  1) Have you ever seen WiFi working in Einstein?  I saw a reference to it being possible, but I've never gotten it to work.  [because Einstein at the moment is way less functional than my 2100]  2) Do you know what the most compatible 'modern' ARM chip would be?  That was going to be my next line of research when I have time.
