Case in point, for my desktop, I have a couple of wireless NICs. The one of interest here is
Code: Select all
scott@broadcom-lm:~$ lspci | grep Network 09:00.0 Network controller: Broadcom Limited BCM4352 802.11ac Wireless Network Adapter (rev 03)
So, I thought the desktop was limited to wired connection - in fact I did some "let's run some wires under the house" to connect the desktop to the router that is on the other side of the house. BTW - the wired connection beats the WiFi every time. Just saying.
Anyway decided to run an experiment on an empty scratch disk (I have a few)
- Disconnect the Cat5 from the box
- Install the above card
- Boot up the LiveUSB of LM 19 MATE that I downloaded today
- Of course the WiFi card was not recognized and I had no internet connection, but I went ahead with the installation anyway.
- Reboot the box and the WiFi still didn't work so I started up the device manager. It complained about no internet but offered to look at the installation media instead.
- So, I inserted the LiveUSB and the device manager was happy.
- Device manager found the source code for the kernel module required for the WiFi chip, compiled it, installed it and then told me to reboot.
- Rebooted the computer and WOW, the WiFi was working.
- Establish a connection with my WiFi router and life is golden
