I assure you, Founder, my network is very secure. It doesn't broadcast its SSID and it's restricted to to only the MAC addresses I've listed. As for WEP, I haven't bothered since apparently, now the algorithim is public knowledge, less than a minute sees those who wish to be so through that particular 'security' measure.
The problem was that I was ending up on my neighbours unsecured network rather than on my own. All sorted now anyway, just a case of checking a different box to make my machine a little less prone to using any connection it could get it's hands on as I moved around the house.
