Note: Broadcom Net Controller Driver issue on ZorinOS
=================================================================================

日前出差，假日在飯店打算用筆電精（ㄕㄨㄚ）進（ㄉㄧㄢˇ）自（ㄊㄧˊ）我（ㄇㄨˋ）時，
發現筆電接不上網路，想著是broswer沒有自動彈出登入呢，老問題了（Win少數的好處就是貼心）
然而：
不是自動logging的問題，而是根本沒有接上wi-fi
一段搜尋後，發現是Broadcom 網卡驅動issue，老問題了
附圖是網卡型號：`Broadcom BCM4350`

Do Script
---------------------------------------------------------------------------------
### 處理自動登入的部份，簡單scripting一下:

#!/bin/bash

# define google checking-website
web_check="http://connectivitycheck.gstatic.com/generate_204"

if curl -s -I "$web_check" | grep -q "204 No Content"; then
    echo "Wi-fi connection in Normal"
else
    echo "Use Browser to login the Wi-Fi connection"
    
    # using xdg to open browser
    xdg-open http://neverssl.com
fi

### 安裝Broadcom驅動的部份：

#!/bin/bash

sudo apt update
sudo apt install -y build-essential dkms linux-headers-$(uname -r)

# install Broadcom STA driver (broadcom-sta-dkms)
sudo apt install -y broadcom-sta-dkms

# remove old driver
sudo modprobe -r b43 b44 b43legacy ssb brcmsmac bcma

# probe Broadcom STA driver
sudo modprobe wl

# restart Wi-fi module
sudo rfkill unblock all
sudo nmcli radio wifi off
sleep 2
sudo nmcli radio wifi on
