[Sergio Castillo <s.cast.lara@xxxxxxxxx>]

I have a Lenovo B5400. When I installed Ubuntu 14.04 wifi didn't work.

I followed the instructions provided by #30 and wifi now works, but I
have the same problem as #13 and #24 : the connection, after 1h or so,
falls off.

I installed the kernel v.3.15  and I had the same problem as #24 when he
did it (wifi appeared to work, but it didn't). I reverted back to
3.13.0-29-generic and when the wifi doesn't work I have to run the
following command:

sudo rmmod rtl8723be && sudo modprobe rtl8723be

Will this be solved? Is someone working on it?

Thanks in advance!
