I am a beginner Linux user and I have a MacBook 3,1 made in 2007 running Lubuntu 16.04 64bit with Network Controller: Broadcom Limited BCM4321 802.11a/b/g/n [14e4:4328] (rev 03), Subsystem: Apple Inc. Airport Extreme [106b:0088] Kernel driver in use: b43-pci-bridge.
The wifi connection is very slow and disconnects often. Since the wifi was working under Mac OSX and Windows on the same computer/router setup, I suspect the solution is to uninstall the wifi driver and install a new one. My question is: which driver do I choose and how do I uninstall the old one and install the new one?
I followed the top-rated response of this post but the problem persists: Installing Broadcom Wireless Drivers
