I have installed Ubuntu 14.10 on my desktop computer in the office, but I'm having troubles with the network. The issue is that I can't make it connect to the network at all, as it displays icon for the WiFi connection and start connecting with it, and when it realizes that there is no WiFi, it sort of connects to wired Connection.
I have tried reinstalling network package that comes with installation, but nothing changed. As this is secondary system, primary is Windows 7, I can ask questions from it. My motherboard is Gigabyte 970A-DS3P with Realtek Ethernet controller.
Here is lshw
