I just installed Ubuntu 16.04 on my Lenovo notebook with a Broadcom network device. My wifi isn't working. I tried to activate a private driver, but that didn't work.

It sounds like you may need to install drivers for your wireless card.

First, can you please go into the terminal and type

lspci -nn -d 14e4:

and tell me what it returns to you?

Also run this: iwconfig after and post the results, too.

Reference: Installing Broadcom Wireless Drivers

EDIT:

It appears that this wifi card is not yet supported according to other users and its not listed in the package install table in the previous link.

  • Ok, in order to install the driver you need, you'll need some sort of Internet connection. Do you have an Ethernet cable you can use? I'll edit my answer to list the steps you must take. – HelpMeee Jul 27 '16 at 03:34
  • Great! Yes, i have a ethernet conection. I will be here :) – Mauro Vásquez Alfaro Jul 27 '16 at 03:42
  • My dearest apologies, I'm sorry to inform you that your wifi card is not yet supported. There hasn't been a workaround found yet; most people advise buying another wireless card. I put links of what other people have tried to do to fix it, but there has been no resolve. Sorry I couldn't be of help! – HelpMeee Jul 27 '16 at 03:47
  • Oh, thats bad... What can I do? I don't want back to Windows :'(

    If there's nothing to do, thank you very much anyway!!

  • You can purchase another wireless card thats supported by Ubuntu. You can find a list of them here: https://help.ubuntu.com/community/WifiDocs/WirelessCardsSupported

    These are the only Broadcom wireless cards that are currently supported on Ubuntu: https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsBroadcom

    You might have to pay to get it installed at a tech support location unless if you are comfortable with installing it yourself.

  • If you want a wireless card that will work on Ubuntu right after you install it (without needing to install packages), Intel ones work very well (See "out of the box"): https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsIntel – HelpMeee Jul 27 '16 at 03:55
