I have just bought a Acer Aspire E11 Netbook. I have installed different Ubuntu Distros but on all Distros there is no WLan Client availbale. I have also installed Win 8.1 which connects via WLan flawlessly. Is there anything I can do about it?

Thanks Franl

  • Please edit your question to include details of your wireless device. Open a terminal and run and post: lspci -nn | grep 0280 Thanks.

Please obtain a temporary internet connection, open a terminal and do:

sudo apt-get update
sudo apt-get install bcmwl-kernel-source

Reboot and your wireless should be working.

NOTE: This technique is valid for Ubuntu 14.04 and later. If your version is different, I urge you to upgrade.

You can try to coax your ethernet to connect with:

sudo ethtool -s eth0 speed 100 duplex full autoneg off

Then see if Network Manager can connect and install the wireless package as above.

  • Thanks for your help. Unfortunately I can`t obtain any internet connection, tried it via Network Wire, sharing my mobile connection via USB. Is there a way around it? A quick fix which makes my wired connection work?
