I just recently returned from vacation from Europe where I took my Lenovo Thinkpad 430. It was working just fine the entire time I was gone where I used a smart phone as a Wi-Fi Access Point to connect to the Internet. Got back home and the thing doesn't even SEE my home Wi-Fi. I can see Wi-Fi connections from my neighbors and other household devices on the list of available networks but my home Wi-Fi does not appear. Tried resetting my home Wi-Fi to no effect. I also used the Windows troubleshooter, and even though it says I am not connected to a network, the first network it shows to attempt to connect to is a smart light bulb with NO internet connectivity.
