Can't connect to the Internet with the built in wireless but I can plug in a Netgear usb wireless adaptor and connect. I also have an Unknown Device in Device Manager that I dont know what it is for. The brand of laptop is Toshiba Tecra M1. I went to the Toshiba drivers site and there are several wireless drivers to download. I am not sure which one to install. Can anyone give some feedback on what I should do to get the built in wireless to work. Also when I click on view available wireless networks with the built in connection there none found. When I do the samething with the netgear adaptor I find several. BTW I have turned on the wireless switch.
