Hi Andre,

I have tried the patch but it is not working for me. When I tried what
you describe in the bug, when I try the last step I get the next error:

mcarmen@matri:~$ sudo /usr/lib/dkms/common.postinst bcmwl 6.30.223.248+bdcom /usr/share/bcmwl $(uname -r)
First Installation: checking all kernels...
Building only for 3.13.0-44-generic
Building for architecture 3.13.0-44-generic
This package appears to be a binaries-only package
 you will not be able to build against kernel 3.13.0-44-generic
 since the package source was not provided

So I have tried uninstall the module using dkms:
1) sudo dkms uninstall -m bcmwl -v 6.30.223.141+bdcom -k $(uname -r)
2) sudo dkms remove -m bcmwl -v 6.30.223.141+bdcom -k $(uname -r)
3) sudo dkms build -m bcmwl -v 6.30.223.141+bdcom -k $(uname -r)
4) sudo dkms install -m bcmwl -v 6.30.223.141+bdcom -k $(uname -r)

But also doing that, the problem is still there. The signal is so low
and it keep disconnecting ...

Thanks for your reply :)

  3) What you expected to happen
  4) What happened instead

  I have just installed Ubuntu on my laptop with a BCM43142 card. I have
  install the recommended driver for this card, the bcmwl-kernel-source,
  however it is not working properly. It detects the different wifi
  networks available but the signal is really low. With my other
  devices, phone, tablet and in windows 8.1 I don't have this issue, and
  I can easily connect to them.

  Because signal is so low, it is constantly connecting and
  disconnecting.
