Lenovo Z50-70 realtek dirver RTL7823BE wi-fi does not connect
I was able to fix this issue after lot of research and facing kernel panic issues. Here is how I fixed it.
Note This can be used for installing any realtek wireless driver
lspci | grep Network
Note: If in this process you get kernel panic issue. DONT PANIC Solution for it is at the end. You dont need to re-install Ubuntu.
Upgrade linux kernel

Install following
sudo apt-get install git build-essential linux-headers-$(uname -r) linux-headers-generic git clone https://github.com/lwfinger/rtlwifi_new cd rtlwifi_new make clean make sudo make install sudo depmod -a sudo modprobe rtl8723be echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
Reboot

My Wi-Fi driver, I think, is not functioning properly on my Lenovo Z50-70 using a Ubuntu 14.04 OS.
After connecting to a wireless network it works for a brief period of time, then, although it shows a stable connection, I can't access any website whatsoever.
I tried the Wi-Fi on Windows 8.1 and it worked perfectly.
Any ideas guys?

Krisiun Lord over 9 yearsI read in other forums that there are no current Ubuntu WiFi drivers for our Realtek card built in on the Lenovo Z50-70. I have been dealing with the same problem for the last week, also running Ubuntu 14.04 on a z50-70 Lenovo laptop and go to the conclusion it will only run properly when running Ubuntu 13.X (or reset laptop by every time the connection fails).

Remus-Andrei Pãun over 9 yearsHello Wild Man. I have run the script from the link you provided. It provides an output but I am unaware of the information I should gather from it. Could you please provide more hints? I mean, I can read the information from this output file but I do not know what to do with it next. Best regards.
