We resently bought several Asus X200 series netbooks for our faculty members. The main attraction of this cute netbook is its light weight and a built in HDMI port. We plan to use them extensively for content delivery in class rooms. These machines are really cheap, costing around Rs17000 ( around $260). The base model comes with Intel® Celeron® Dual-Core ~ 2.58 GHz Processor and 2GB ram, DOS operating system. It has an 11.6 inch LED display.
Our idea was to put ubuntu 14.04 and deploy the machines. The machine has an ethernet port and wifi port. Installation of Ubuntu 15.10 was a smooth affair. Unfortunately, the broadcom wifi interface did not work out of the box. Here is what I did to fix the issue.
- Find out which wifi chip is used.
$lspci 
The wifi chip is Broadcom Corporation BCM43142. You have to download and compile the kernel module for this chip.
2) Make sure that the machine is connected to internet and the apt sources are properly set up
3) Update the machine
$ sudo apt-get update
4) Finally instal the bcmwl driver.
$ sudo apt-get install linux-headers-`uname -r` dkms build-essential bcmwl-kernel-source
This will downlad necessary driver your wifi will be up and running. The above line installs dynamic kernel module support and compiles the broadcom wireless driver.
