I just installed Ubuntu on my MacBook Pro 9,2 (dual boot with rEFInd) and I'm experiencing constant drops of my WiFi signal.

I followed the instructions listed here Installing Broadcom Wireless Drivers to install drivers. I had to install linux-firmware-nonfree and firmware-b43-installer. My network issues persisted and I followed the debugging instructions on this page. It suggested that I ignore IPv6 so I did that but it doesn't help. I've been Googling for a few hours but nothing seems to work.

I ran the wireless script and here are the results.

    @LIttleAncientForestKami I've looked for it quite a lot but cannot find a solution for my particular model – Roemer Bakker Mar 11 '15 at 9:04
  • does this occur only on battery? if so, try sudo iwconfig wlan0 power off, which should disable power management for the wlan0 adapter. – sostacked Jun 9 '15 at 19:58
  • @sostacked Oh hey you may actually be right. I'll try it later. I mainly use OS X again but thanks for the help! – Roemer Bakker Jun 10 '15 at 7:35
