Linux Ubuntu Ethernet Driver Sorunu

Linux Ubuntu işletim sistemini Lenovo G710 laptopuma sorunsuzca kurdum fakat ethernet kartımı görmedi. Yükleyip sorunsuzca çalıştırabilmem için ne yapmam lazım. Terminal'e LSPCİ yazınca bunlar yazıyor:

Bir Allah'ın kulu bilmiyor mu bunun çözümünü ?

Adam ne güzel anlatmış.
Kablolu ya da teldenki neti pc ye bağla aşağıdaki adımları yap

1. Run
   sudo apt-get install linux-headers-generic build-essential dkms broadcom-sta-modules
   If it freaks out with the first package, just skip that one.
2. Download this deb package.
3. cd into the directory containing the package.
4. Install it using
   sudo dpkg -i wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb
5. Activate it.
   sudo modprobe wl
6. Done. It should work now.
