You've not stated how you're trying to connect to the internet. If it's by using a router connected to your laptop via an ethernet cable then the 'Ethernet Controller' reference does look worrying. (It's also possible, depending upon your means of connection, that the 'Modem Device' might be relevant).
If you're trying to make a wireless connection it would help to know where your problem arises. Is it because your laptop can't 'see' the router at all, or simply because it can't connect to it? You might need to go into your router's settings, using a computer which will connect to it, to check how its currently configured. (My own router is set not to even advertise the existence of a wireless network, yet alone accept any new connections).
If you do require any drivers, they should be here:
