We configure interface wlan0 to use WPA in roaming, and static ip address for network id home.[3]

To Do
Issues
- Issue — Frequently losing WiFi connection, without reconect.
- Workaround — Use a cron script to detect and force reconnect * * * * /usr/local/bin/testwifi.sh 2> /var/log/testwifi.log
- Crontab line, edited with
sudo crontab -e
*/2 * * * * /usr/local/bin/testwifi.sh > /var/log/testwifi.log 2>&1
- /usr/local/bin/testwifi.sh
#echo '/usr/local/bin/testwifi.sh log'
TESTIP=172.19.100.107
#ping -c4 ${TESTIP} > /dev/null
/sbin/ifconfig wlan0 | grep --quiet $TESTIP
if [ $? != 0 ]
then
logger -t $0 "WiFi seems down, restarting"
sudo /sbin/ifdown --force wlan0
sleep 10
sudo /sbin/ifup wlan0
else
#logger -t $0 "WiFi seems up."
