I've just purchased a notebook lenovo b50-80, mate ubuntu 15.10 installation with bios in legacy mode

I made several attempts to operate the card by following this guide: How do I get a Realtek RTL8723BE wireless card to work?; and this procedure that i found here: https://github.com/lwfinger/rtlwifi_new/issues/28#issuecomment-172619447 :

git clone git://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
git checkout rock.new_btcoex
make
sudo make install

Reboot. After the system comes up:

sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be ant_sel=1

Now test. If that still does not work, then try

sudo modprobe -rv rtl8723be sudo modprobe -v rtl8723be ant_sel=2

I also tried to enter several parameters in rtl8723be.conf but nothing ... the most i obtained was a short connection after a reboot (3-4 min) followed by disconnection and lack of networks in the Network panel.

the output is:

09:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723] (rev ff)
    Kernel driver in use: rtl8723be

This is the output of rfkill command:

maria@maria-Lenovo-B50-80:~$ rfkill list

    Soft blocked: no
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth

You could make some mistakes when installing the drivers.

I packed them to PPA, it is easier to install. Run these commands (carefully, one by one):

cd rtlwifi_new
sudo make uninstall
sudo rm /etc/modprobe.d/rtl8723be.conf
sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

Then reboot and test. Maybe you will need ant_sel parameter. Maybe not.

  • ndiswrapper is obsolete. It needs WindowsXP drivers. But some work with linux well, but I do not track them. – Pilot6 Feb 09 '16 at 15:15
