I did all of the above with the exception of installing
Intel Chipset Software Installation Utility, v.9.2.0.1030, A04
because WIndows said I had a newer version already installed. I still can't connect to my wireless network. I can see it listed as an available network with a strong signal, but when I try to connect, it runs for a while and then I get a message about Windows being unable to connect. I'm using my neighbor's wi-fi for now.
Also, this afternoon I was in an area with a strong free wi-fi signal but my laptop didn't even "see" that signal. It did pick up about 30 other wi-fi networks in that area, so I couldn't understand why it was doing this.
Thanks
