The rest are secured with WEP at least.

The problem with a lot of people having unsecured routers, they've most likely not set their passwords from the default for the admin options either, so you could easily (and maliciously) change their settings.

I remember far too many businesses in London had unsecured networks. Still do most likely.

Once I was waiting for my girlfriend (now wife) that time so I got my notebook out and see if I could hook on to any signal.

I managed get into someone's router though, got connected, checked default gateway and logged in.

I emailed the person though, informing him / her of the lack of security and that was it.

Well you'll get to meet the neighbours if nothing else! I guess a few flyers could do the trick. Drop them into people's houses, point out that they're responsible for what goes through their broadband and that could range from hacking to stuff much worse. Scare them into calling you!

Yes I'm mean

These days people can pick up a cheap computer for less than £300, wireless is easy to plugin and ADSL is extremely affordable now. So everyone has it, but most of them don't have a clue how best to use it!

People are getting wiser these days.

Most networks I come by uses WEP. I use WPA.

Deron – I've often been tempted to wander around and offer a service to people to secure their connection! Would be quite a little money maker at first
