Hi all,

forgive me i'm only learning in the wireless lan area regarding to networking etc .
Am keen to know the following please :

A) When connected on a wlan say you and flatties ar sharing a router  etc  how much, and can you see each others folders etc
on there pc's (laptops ) obviously I want to stop this if this is the case ??..

If so or if can be provisioned/  stopped how and where ?

B) if i access a free public hotspot my mac address would obviously be shown, will my firewall prevent any nasties if it is a open network i.e unsecured and open, or do I need to install something else I'm already concealing my IP adress via several proxys for online security etc .

I'd apprecaite any feedback,links etc around this topic and applications etc if any ..

Cheers
