I would recommend against following the instructions in #29. For me it causes a kernel panic I had to fix by blacklisting the rtl8723be driver in recovery mode, and the makefile also seemed to delete the existing driver already in the kernel, so I ended up reinstalling the OS to fix it.
As for how I got my wifi working:
Installed 14.04 from the live disk.
Did a full update and upgrade of packages while connected via ethernet.
This should give you the 3.13.0-29-generic #53-Ubuntu kernel.
When you reboot into this kernel, you will see the error in #19 in your dmesg about missing firmware.
As mentioned in #20, you will need to download the rtl8723befw.bin firmware and then copy it to /lib/firmware/rtlwifi/
Reboot and wifi will work.
So two questions-
Will this firmware be included in a future kernel update for Trusty?
Will there be an updated iso for Trusty at some point with a newer kernel, so that this wifi card will work out of the box?
