Computer changed its network settings by itself?
Before I ask my question, I would like to make the point that I'm not entirely certain that my regular means of internet access are, in the simplest terms, "legal". Under normal circumstances, I would usually connect to a wireless network called "linksys" which I understand is a wireless router company. The only problem with that setup is that the router I own (or rather, my mother owns) is on the first floor of our house, and while I normally use my laptop on the third floor, I don't receive signal from our router. Instead, I believe I've been catching signal from a neighbor or something (Though I don't know how this would work either, seeing as our router is still closer, and I don't have an external antenna).
That's how it usually works for me. However, this week, I lost the signal for some reason, and not only the signal, but also, when I attempt to diagnose the connection problem, I'm told that the settings saved on my copmputer do not match the requirements of the network. And I know I never changed my settings, nor do I even know how. Since the network in question comes from an unknown source, I can't fiddle with the router. Is there any other way I could experiment with solving the problem? Thanks.
