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 linux-firmware Reboot and enjoy If you still have problems, you may need to add an option: echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf then reboot again. Expanation is made by *chili555* in this answer <http://askubuntu.com/a/729660/167850>. This is the same driver as https://github.com/lwfinger/rtlwifi_new, rock.new_btcoex branch but packed as dkms. You can see all that at https://github.com/hanipouspilot/rtlwifi_new/tree/rock.new_btcoex 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 HERE <https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files/rtlwifi-new-dkms_0.10_all.deb> You will also need DKMS installed. You can find the DKMS package for Ubuntu 16.04 HERE <http://mirrors.kernel.org/ubuntu/pool/main/d/dkms/dkms_2.2.0.3-2ubuntu11_all.deb> 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 THIS ANSWER <http://askubuntu.com/a/762255/167850> to fix it. Meanwile I will try to find a way how to sign the module in the PPA. There is a way how to do it. share <http://askubuntu.com/a/635629>improve this answer <http://askubuntu.com/posts/635629/edit> edited Jul 21 at 18:23 <http://askubuntu.com/posts/635629/revisions> answered Jun 12 '15 at 15:25 <http://askubuntu.com/users/167850/pilot6> Pilot6 <http://askubuntu.com/users/167850/pilot6> 25k104094 On Sun, Jul 31, 2016 at 11:26 AM, Nat Taylor <[email protected]> wrote: > DuckDuckGo told me this, here's the link for more too ( > http://askubuntu.com/questions/635625/realtek-8723be-wifi-problem#635629 > ): > Realtek 8723BE Wifi problem > <http://askubuntu.com/questions/635625/ddg#635629> > > 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 linux-firmware > > > Reboot and enjoy > > If you still have problems, you may need to add an option: > > echo "options rtl8723be ant_sel=2" | sudo tee /etc/modprobe.d/rtl8723be.conf > > > then reboot again. > > Expanation is made by chili555 in this answer > <http://askubuntu.com/a/729660/167850>. > > This is the same driver as https://github.com/lwfinger/rtlwifi_new > <https://github.com/lwfinger/rtlwifi_new>, rock.new_btcoex branch but > packed as dkms. > > You can see all that at > https://github.com/hanipouspilot/rtlwifi_new/tree/rock.new_btcoex > > 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. > > --Pilot6 <http://askubuntu.com/users/167850/ddg> > > On Sat, Jul 30, 2016 at 6:40 PM, John Jason Jordan <[email protected]> > wrote: > >> On Sat, 30 Jul 2016 14:51:24 -0700 >> Charles Hill <[email protected]> dijo: >> >> >I don't subscribed to the ship it now with a known bug especially when >> >it's wireless and patch it later. >> >On a laptop "Wireless" is a core function.. and if it's not stable it >> >lends to a miserable user experience. >> >> There's always a trade-off between being able to run the latest versions >> of programs with cool new features, as opposed to reliability and >> stability.
