I have a Sony VAIO running currently patched Windows 7 Professional, am able to connect and use any WiFi connection except the HotSpot on my Verizon Wireless cell phones (2 of them). This used to work until the last month or so.
When I connect the VAIO to either HotSpot, it gets an IP address but no default gateway, and was set to Public because there was no gateway. I have been able to change the connection from Public to Home, but it still shows no Internet connection.
My other devices and laptops (running Windows XP, etc) can connect through the HotSpot just fine, so I know the HotSpots function normally.
