Jun 1, 2014 - You likely don't need to install anything. The drivers for many of the Realtek wireless adapters are already in-tree. I have an 8192CU myself.

I have installed Ubuntu 15.04 on my laptop with RTL8723BE Wi-fi card. But it is always disconnecting from network. I have tried echo 'options rtl8723be fwlps=N ips=N' sudo tee /etc/modprobe.d/rtl8723be.conf but that didn't helped. What can I do to prevent the wifi from disconnecting? If I upgrade to kernel 4.X, will it help? ~$ lspci -knn grep Net -A2 09:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.

First of all remove the settings you made. Sudo rm /etc/modprobe.d/rtl8723be.conf If you do not have this file, nothing is wrong. Then install a good driver sudo add-apt-repository ppa:hanipouspilot/rtlwifi sudo apt-get update sudo apt-get install rtlwifi-new-dkms Reboot and enjoy If you still have problems (low signal), you may need to add an option: echo 'options rtl8723be ant_sel=2' sudo tee /etc/modprobe.d/rtl8723be.conf then reboot again.

This is the same driver as, rock.new_btcoex branch but packed as dkms. You can see all that at If you also need bluetooth working, run also: sudo apt-get install rtl8723au-bt-dkms linux-firmware Note: Support for 4.2 kernels and Ubuntu 15.10 has been added to the PPA. For kernel 4.2 the bluetooth driver should not be installed from the PPA. There is already native support of the bluetooth adapter in kernel 4.2.

Offline guide If you do not have any internet connection, you can download the package using another computer, a phone, etc. The package is You will also need DKMS installed. You can find the DKMS package for Ubuntu 16.04 Copy these two files to the Ubuntu Home folder (~/) and run in terminal sudo dpkg -i dkms*.deb rtlwifi*.deb Then reboot. Important: For new Ubuntu kernels installed on a system with Secure Boot on UEFI, the unsigned kernel module may not load. In this case see to fix it.

Update: I have now a laptop with this adapter. It works perfectly on the 4.8 kernel that is available in Ubuntu 16.10 and 16.04.2.

Installation of a custom driver is required only for kernels older than 4.8. I suggest installing the 4.8 kernel to Ubuntu 16.04 if it is not installed yet by sudo apt install linux-generic-16.04 The device should work well after a reboot. But still if your laptop has only one antenna and it is attached to a 'wrong' connector, setting ant_sel=2, or and_sel=1 may be required. I can confirm that this works perfectly on laptops from the HP 15 series with the Realtek RTL8723be on Ubuntu 16.04. It requires both the installation of rtlwifi-new-dkms from ppa:hanipouspilot/rtlwifi and writing the ant_sel=2 directive. Unfortunately, it requires you to disable Secure Boot. But on all Ubuntu versions that ship with a more recent kernel, e.g.

Ubuntu 16.04.2, you can probably remove this custom driver again, right? Then, after switching back from this driver to the one provided by the kernel, it should be possible to enable Secure Boot again. – Nov 21 '16 at 5:34. If your Wifi drops after a while and you dual boot with Windows On HP 250 G4 (using rtl8723be), I at first had the antenna bug: wifi signal was too low: It was solved after installing new driver and setting ant_sel=2, just as described here. But then came the 2nd problem: wifi was working fine for some time (sometimes 2 hours) then suddenly going slow and eventually disconnecting. Changing parameters (ips, fwps.) didn't help. I finally found that removing Windows 10 fastboot (in Windows energy settings) solved the problem.

Just took a HP Stream 13 and wiped it, put Ubuntu 15.10 on it symlinking all home folders to a 64GB SD card to expand the 32GB SSD. Then ran into the dreaded rtl8723be problem, which I have also noticed on a HP 430 work laptop that had a different variant. After a lot of messing, I finally find there is actually 2 issues here. • The WiFi driver needs swapping as stated above, to cure drop outs of the card which require network manager to be restarted or card resynched with network. Update the driver as stated.
