5 sometimes 4
1 unsecured, which is mine, but I think everyone should follow the sharing principle, lock your box, and open the access point.
I actually run an open network for a number of reasons
-I cant be bothered to set up access for overnight guests and other visitors
-I explicitly allow a neighbour to share
-I dont think classic WEP, that some of my hardware is, is at all secure. 5 minutes searching on google will show you how to break into pretty much any WEP secured WAP, 64 bit or 128 bit
-Knowing the net is open forces me to lock down the boxes better. All firewalled, no SMB connectivity (SSH/SCP to the server only).
i have a bit of basic traffic shaping to ensure that i still have _some_ bandwidth left
i'm also somewhat unconvinced that the nefarious types of N12 are fapping off to bambi, stealing my porn passwords or reading my email.
my router - which _is_ secured - tells me that im the only connection in 15 months anyway.
