I am staying in a corporate rental. The houses set aside for this purpose are interspersed with normal rentals as well as houses people have purchased (though I would never count myself among those. These houses were just tossed up, not built). All of these homes are placed extremely close together--if they were any closer, we'd be talking zero property lines.
One of the issues I had to work with way too much persistence was the lack of promised cable service to our unit. I don't care about the TV, but I had paid extra to get cable internet and I was going to have that. However, until the cable was installed, I had no internet. I noticed that there was an unsecured Wi-fi in the immediate area and so I latched onto that. Unlawful, I know, but I had to use it as there also was none of the promised phone service. It still was not optimal as you just can't in safety go to your bank's website, for example.
I have a MacBook laptop and can see the names of the networks in the area, whether I can link to them or not. Most have regular names like the owner's name, the name of the provider with a couple of numerals afterward, etc. But a couple are extremely hostile. For example, one is named "Getyourowndamnconnection" and another is named "B*tchpayforyourinternet". If you don't wish to share, then get your own darn password!
Glad I'm not hanging around here.
Oh by the way, the cable and associated internet that I paid for are up and running just fine now!
