Download this driver

make sure it's unzipped on your desktop then open terminal and type these commands:

cd Desktop

then

cd rtlwifi_new-master

then

sudo make install

Reboot after installation has finished.

  • Nothing changed. What did that to my wifi? I forgot to tell that when i turn wifi off and turn it on internet works for some seconds. – user3396072 Oct 17 '15 at 15:36
  • That includes the driver for BCM43142. Exact same one i'm using at the moment. Did it install ok without errors? – William Oct 17 '15 at 15:39
  • Yes. Everything was fine. Oh what can be wrong :/ its soo flustrating :( ..... Oh wait its working i will wait some minute and if everithing will be fine i will mark this answer solved :) – user3396072 Oct 17 '15 at 15:44
  • Ok its not disconnecting but its slower than week ago nevermind you helped me so thank you very much :) – user3396072 Oct 17 '15 at 15:53
  • Glad i could help. – William Oct 17 '15 at 15:54
  • One question. Can i remove that file from my desktop? – user3396072 Oct 17 '15 at 16:13
  • Yes if it's installed you can delete it. But every time you update your kernal you will need to reinstall it so maybe bookmark the driver download page :) – William Oct 17 '15 at 16:15
  • @user3396072 Your accept of this answer is wrong. That Realtek driver can't do anything good to your Broadcom adapter. – Pilot6 Oct 18 '15 at 14:31
