I have just put a new hard drive in my laptop - a sony vaio
It will no longer connect to my university internet through a cable which I just plug into the wall. It has no issue finding wireless connections. I have tried changing the connection cable but it had no effect. In device manager under network adapters it lists: Atheros AR9285 Wirless Network Adapter and there are no warnings associated with that. Underneath in other devices it states that the Ethernet Controller has no driver installed. Is this related?
Any help much appreciated :)

A missing Ethernet driver will prevent the wired connection from working.
You can probably use your wireless connection to visit the support section of the the Sony web site and download the missing driver(s) and get instructions on how to install the downloaded driver.
