--apt-get install wavemon (monitors wifi connection statistics similar to iptraf)
--Making some tweaks to /etc/wpa_supplicant.conf and /etc/network/interfaces to see if it improves connectivity to PAL--tried 'wpa-roam' vice 'wpa-conf' but that didn't seem to work--did comment out all networks other than PAL from wpa_supplicant.conf
--Added 'sleep 5' to /etc/init.d/keepalive-ping.sh prior to the ping call to allow time for new /etc/network/interfaces and /etc/wpa_supplicant.conf to bring network up.  Also removed 'sleep 15' from /etc/init.d/time-update.sh
