I am using Lubuntu 14.10 on my Macbook 3,1 and I switched to the b43 driver as suggested here. The problem I have with this driver is that I cannot detect and connect to the 5GHz band wifi networks.

Is there anything I could do to be able to connect to that frequency band again?

In kernel 3.17 and above there has been some success in getting 5GHZ to work with the b43 driver, so here are the directions for installing the 3.18 kernel, I can not promise that it might not cause some other kind of issues.

cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-vivid/linux-headers-3.18.0-031800-generic_3.18.0-031800.201412071935_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-vivid/linux-headers-3.18.0-031800_3.18.0-031800.201412071935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.18-vivid/linux-image-3.18.0-031800-generic_3.18.0-031800.201412071935_amd64.deb

sudo dpkg -i linux-headers-3.18.0-*.deb linux-image-3.18.0-*.deb

Reboot

Set the channel manually on the router and in network manager that you want to connect to, make sure it is within the range of your devices channels by looking at the occupancy section in the file you posted. Changing the channel from auto to fixed is your best option.

Also linux connects best to wpa2 AES CCMP Only not mixed mode or TKIP.

Do:

sudo rm /etc/udev/rules.d/70-persistent-net.rules

Reboot
