Is This Really Stealing?

Is this stealing?  

One of the neighbours around here has an unsecured wifi network.  I discovered it quite by accident the other day when I was in the living room with Jean watching "Anne of Green Gables".  I was actually using my own silly wifi, provided by 3, the most rubbish internet providers on the planet - and it kept dropping out! So finally, out of sheer frustration and total annoyance, I unplugged the stupid thing (its one of those dumb dongle things, totally useless) and shut down the laptop.  But a little later, during a Gilbert-free moment, my attention was wandering and I decided to imdb Jonathan Crombie (aka Gilbert Blythe) to see what else he's been in, how old he is, is he married (hehehe) and all those important things.... and I suddenly realised that I was connected to the net, but the dongle WASN'T PLUGGED IN!!!!  Magic!  And the best bit of all - it wasn't dropping out!

So since then, if I have some important (i.e. more Gilbert-spotting) internetting to do, I just pop downstairs to the living room, turn on the laptop and voila!  Best connection ever!

So is this wrong?  I mean, I pay that stupid 3 a whopping £15 a month for crappy broadband internet which constantly drops out, has a 3GB limit per month, and a minimum 12 month contract (expiring in April - so I'll be paying £60 to them for nothing when I go home).  Their service is so bad that if I have photos to upload to my blog, or if I have attachments I have to send with my emails, I have to do it at school (in fact I have to have my blogger log-in page as my home page or else it just won't load up when I use the 3 internet at home) - how bad is that?!  And as for automatic software updates, well!  Just won't happen with the stupid dongle setup.

So if my neighbour is stupid enough to have an unprotected wifi network, is it then wrong for me, a mostly law-abiding, broadband-paying customer, to take advantage of it?  Especially as I'm not getting the service I pay for...? I mean, it's not like I'm choking up his bandwidth, logged on all evening, watching lots of youtube videos, downloading huge files... oh hang on, I am....!  Oops...
