My broadband at home isn't too hot and drops out for hours at a time (I've already ascertained it's the providers fault- I'm at the distance limit to the exchange). I can currently see two other networks. One is a closed network that requires a password; the other has a poor signal and I can log on (am actually posting from it now). I'm assuming that the other two i can see are my next door neighbours- any way I can pin point the direction? And I assume that my macbook is secure to use the other open network (it is firewalled)?
