After installing Ubuntu 12.04 LTS in my laptop HP ProBook 855 G2, I found that my wireless network wasn't working. I noticed many people had the same problem, all of them having the same card RealTek RTL8723be (it shows as b723 with
lspci). I already tried the following suggestion:
- Pull the repository at https://github.com/lwfinger/rtlwifi_new from a working computer and copy it to a USB stick.
In the computer to be fixed, load stick and
cdto folder. Then run:
make sudo make install sudo modprobe rtl8723be
At this point, the wireless network will be enabled, but it won't find any APs to connect with. I have tried tweaking the driver options as suggested in many places:
echo "options rtl8723 ips=0 fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
But this didn't work. Any suggestions? Thanks.
