So Fedora has been disconnecting me a lot lately from my home wifi and I think it’s because I have disabled a lot of background services that I don’t need. Anyway, I’m trying something new:

yum remove NetworkManager

mkdir /etc/wifi
wpa_passphrase "your_ssid_here" > /etc/wifi/home.conf

Run this script as root when wanting to connect to wifi (assumes the wlan0 interface):

#!/bin/bash
pkil=`which killall`
intf=`which ifconfig`
scan=`which iwlist`
wpas=`which wpa_supplicant`
dhcp=`which dhclient`
ifce="wlan0"
while true
do
	ping -c 1 google.ca > /dev/null 2>&1
	if [ $? -eq 0 ]
	then
		sleep 10
		continue
	fi
	for file in /etc/wifi/*
	do
		$intf "$ifce" up
		ssid=`cat $file | grep -i 'ssid' | sed -e 's/^[ \t]*ssid="//g' -e 's/"[ \t]*$//g'`
		exis=`$scan "$ifce" scan | grep -i "$ssid"`
		if [ "$exis" != "" ]
		then
			echo "[`date`] connecting to [$ssid]..."
			$pkil -9 wpa_supplicant > /dev/null 2>&1
			$pkil -9 dhclient > /dev/null 2>&1
			$intf "$ifce" up
			$wpas -Dwext -i "$ifce" -c "$file" > /dev/null 2>&1 &
			$dhcp "$ifce" > /dev/null 2>&1 &
			break
		fi
	done
	sleep 10
done
