However, the wifi still connects intermittently. We have tried the method recommended in the post and we also tried installing firmware-b43. To remove it use the command below:Ĭomment by adding # in front of the line blacklist bcm43xx
#UBUNTU BOOT USB FOR MAC INSTALL#
To install firmware-b43, we must first remove the bcmwl driver.
#UBUNTU BOOT USB FOR MAC DRIVERS#
Install Broadcom Drivers firmware-b43-installer We suggest you test with this driver first. To install bcmwl-kernel-source, you just need to use the additional drivers from the GUI. Install Broadcom Drivers bcmwl-kernel-source The two drivers are bcmwl-kernel-source and firmware-b43-installer. We will present both drivers for you to test. the links is below.īased on the linked post above, there are 2 drivers for BCM4321. There is a detail troubleshooting post on solving Broadcom wifi issue. To resolve the issue, we have to reboot the system few times until the wifi works. Sometimes, the wifi is able to established connection, sometimes it don't. However, subsequent reboot shows that the wifi is not able to established connection consistently.
We manage to established connection with our router. The wifi is also able to scan and detect all the routers. The system is able to detect the wifi after installation of the driver. Click on " Using Broadcom." and click Apply Changes. If you prefer to make the wifi work, You can choose to install the third party driver. You can just ignore this section and you are good to go.
If you are happy with just wired network connection. In fact, if you search the web there are many issue relating to Broadcom wifi driver, especially on older chipset. This is the only persistent problem with some of the Ubuntu distribution.
If you intend to use the box with VNC server or to boot without monitor, use the original open source video driver, DO NOT install Nvidia driver. This creates problem if you intended to boot your box without monitor attached. Our testing with Linux Mint also shows that if Nvidia driver is installed, Linux Mint would not launch X windows session during boot up, if monitors are not detected. If you intended to install VNC server, we would suggest that you keep existing driver. We have discovered that Nvidia driver does not work well with RealNVC in Ubuntu. If you are happy with the video you can leave it as default. Select " Using Nvidia." driver and click Apply Changes.
