ubuntu can't connect to wireless

  • 772

I installed ubuntu 12.04 on my dell inspiron 5720 and I can't connect to any wireless networks, at the right top, it doesn't show any networks.

I tried both the 32bit and 64bit versions, I reinstalled my os several times, I googled a lot, and none of it seems to work. My pc is dual boot with windows 7, and the wireless is working fine there so my network card is allright

I searched for additional drivers in system settings and it can't find anything then I went to the software-center to install of the broadcom stuff but still no wireless

the output of 

lspci -vvnn | grep 14e4

is

02:00.0 Network controller [0280]: Broadcom Corporation Device [14e4:4365] (rev 01)

it doesn't even show wlan

wireless

  1. Please see here. You have the same device and need the same fix, including a 64-bit installation: Dell Inspiron 5720 Wifi (Broadcom BCM43142, Ubuntu 12.10)
