I wouldn't do it, since I also would not know whom else could be doing the same thing without authorization to access (and what they might be using the service for). It seems like it could create a mess I wouldn't want. (And, it is stealing; I leave my B-B-Q in my backyard, for instance, but that's not an open invitation for neighbors - who can see it - to use it without my permssion.)



Also, even if it appears that the Network is available, it actually might not be: It could prompt for a password, etc.

My WI-FI often shows nearby networks that are seemingly available, but, they really aren't - as long I don't also have an account with those providers.

"HotSpots" - for WI-FI - are different; certain areas and businsses are wired for people to use the services freely, but make sure those firewalls are running .
