Ubuntu – RTL8723be: poor and unstable wireless in Ubuntu (from 14.04 to 15.04)

driversrealtekrealtek-wirelesswireless

I have a Lenovo G40-70 laptop, which comes with RTL8723be driver.

I'm using Ubuntu 14.04 LTS (with Kernel 3.16.0-38-generic), but this bug also occurs in 14.10 and 15.04.

Even with options rtl8723be fwlps=0 ips=0, the problem is not fixed yet. Wireless is unstable, lots of websites keeps loading forever and Ping command frequently shows data loss. It's very annoying. 🙁

BIOS version is the latest.

Blacklisting ideapad_laptop also doesn't work.

Sorry my english and thank you!

You tried an old solution. You need to install another driver. Run in terminal

sudo apt-get install git build-essential
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

Then reboot.

You also can remove that file with options rtl8723be fwlps=0 ips=0.

Note You will have to re-install it after each kernel upgrade.

New option:

You can now use a ppa instead of manual compiling:

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

Hm, cant say for sure, the freedomben driver actually worked for me...

so, if you're not sure how to, do the following (I'll avoid git, for simplicity);

goto: https://github.com/FreedomBen/rtl8188ce-linux-driver/tree/ubuntu-14.04

... and download the zip file (right-hand side)

... when downloaded, extract the .zip file and 'cd' into it.

finally run install.sh ($ sudo ./install.sh).

Instructions can also be found on git...

Hope it helps

You can install a better driver this way:

sudo apt-get install -y git build-essential
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install

Note You will need to reinstall the driver after each kernel upgrade.

Update I made a DKMS version of same driver. It can be installed by

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms

If you are on Ubuntu 14.04 or 15.04, I recommend to upgrade linux-firmware from same ppa.

sudo apt-get install linux-firmware.

In this case the driver will be automatically rebuilt after kernel upgrades.

In case you install from PPA, you do not need to install from git
