My next door neighbour came over a few minutes ago and asked if she could share my WiFi connection on her phone because her connection was not working for whatever reason. Anyway, I accessed my WiFi connection on her phone and put in my password, and it connected for her. I told her to please disconnect once she was done. My question is did I do something I should not have done? I did not want to be churlish and say "no, you cannot share the connection." It is the first time she has ever asked me anyway, so I concluded she must really need it. Please tell me what I should do to make sure she is disconnected by tomorrow. Tell me anything else I should know, too. I can turn off my WiFi from my computer at anytime and turn it on again. If I do that and have not given her the password, will she be disconnected and not be able to reconnect again? Thanks.
