The pineapple status lights from boot should show green orange and red and then just green and blue will flash for a min "checking for firmware" then all lights will come on. If receiving successful replies with ping to 172.16.42.42 and replies from 172.16.42.1 I would say that your interfaces are correctly configured but your internet sharing is not. Open cmd with admin privileges type ncpa.cpl check your internet facing interface has sharing configured and is allowing the pineapple interface to share internet connections. if so and is all correct but you still can't connect do the following in cmd with admin priv type ipconfig/flushdns then ipconfig/release then netsh interface ipv4 reset. Reboot open cmd again with admin priv type netsh interface show interface to see your interfaces now to configure them for your internet facing adapter type netsh interface ipv4 set address name="your internet facing interface" source=dhcp then type in netsh interface ipv4 set address name="your pineapple interface" source=static address=172.16.42.42 mask=255.255.255.0 Now set DNS netsh interface ipv4 set dns name="your pineapple interface" source=static address=8.8.8.8 primary now type in ncpa.cpl to bring up network connections and configure sharing on your internet facing interface right click the interface select properties select the sharing tab, tick top left checkbox and select your pineapple facing interface where it says home networking connection. Click ok. If you get any pop up window saying that the pineapple interface ip address will be changed. In cmd type ipconfig/all to see your ip addresses for the interfaces and reconfigure to the correct config. make sure they are correct. The internet facing interface is using dhcp and your pineapple interface is static and is using the correct static IP address 172.16.42.42 mask 255.255.255.0 and DNS 8.8.8.8 you should be able to connect now. That should do it. You could do it all through network connections using GUI if you wish.
