I have previously connected to wireless internets at my friends' houses but
cannot connect now that I am at home. I have never connected at home.
However, I have two other computers that are running XP that are able to
connect. I have Vista on my laptop. The computer reads that there is
excellent strength but when I try to connect it says it is unable to because
of low connectivity. I have read their suggestions and have done them all. I
still can't connect. I am usually pretty good with computers as a lay person
but this really stumps me. Please help.
