Starting a couple of weeks ago, I have been unable to connect to the
Internet using a wireless connection from most places where I used to be able
to connect from (e.g., the public library, a local supermarket, shopping
center), while other people (probably people who do not have Vista) seem to
be on line. The "Connection and Sharing Center" shows that there ARE strong
connections, but "Local only." This is the case whether I use Firefox or IE7.
I HAVE read the thread:
Can't get wireless laptop to connect in Network & Sharing
I did (eventually) find the message from McAfee that they mangled things;
however, in the course of trying to follow their solution and with the "help"
of their on-line chat, I managed to uninstall McAfee and cannot reinstall it,
so that cannot be the problem.
Any help that people can give me will be welcome, but I won't be able to
read it unless I dial in or am able to plug in to a library cable. (Note: I
-am- able to dial in, and eventually the library's cable connection will give
me a browser I can log in on.)
