I have the same problems that several people had before. Wifi ain't working.

However, installing the libnl-3-200 libnl-route-3-200 and libnl-genl-3-200 did not work, nor did downgrading.

At first it worked, however, after a reboot it stopped working again (not after the one immediately after the reinstallation but after the weekend ...) So I tried to fix it again, downgrading etc. Installing the libnl-* files did neither work using apt-get nor work by doing so manually. After hours of doing so I got frustrated and reinstalled elementaryOS for the first time. Again non aforementioned ways of fixing WiFi worked... after another hour of trying all fixes I could think of I'm now in the process of reinstalling it again (first time with active Ethernet ... )

Can anyone point out another way of fixing the WiFi

If you need any information to help me, please say so and I will do my best to deliver that info.

You might be missing the b43 firmware drivers.

Open terminal and check your Wireless card model

lshw -C network

For models: * BCM4306/3; * BCM4311; * BCM4318; * BCM4321; * BCM4322 (only 14e4:432b); * BCM4312 (with Low-Power a.k.a. LP-PHY).

Install with sudo apt install firmware-b43-installer

For models: * BCM4301; * BCM4306/2; * BCM4306.

Install with sudo apt install firmware-b43legacy-installer

  • The BCMx number does not really matter apparently. If you do lspci -vvnn | grep 14e4, you should pay attention to the number behind 14e4. For example: BCM4321 has 2 drivers. 4328 has b43 and 4329 has bcmwl-kernel-source. The following webpage also has a nice table of support: linuxwireless.org/en/users/Drivers/b43
