Hello, I'm new so please bear with me. This connection is established using a desktop pc also using Win 7.  Connection is via a TP-Link ADSL2+ modem/router - TD8817 through TPG as ISP. I've sifted through all the drivers the wonderful Dell site provides, using the service tag number, and downloaded and installed quite a few that might possibly be correct.  But Device Manager still shows Broadcom USH and Ethernet Controller as having no drivers.  Both show manufacturer as "Unknown", so that's made it difficult to pinpoint the correct drivers.  Of course, clicking "Update Driver" can't work as the laptop is not online. Any help would be much appreciated as I've spent many, many hours so far on trying to fix this and be able to use this powerful laptop on my home broadband. Thanks, Peter
