wireless networks no longer seen

Please do:

echo "options ath5k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath5k.conf
sudo modprobe -rfv ath5k
sudo modprobe -v ath5k

Then:

gksudo gedit /etc/pm/power.d/wireless

(this will create or edit a configuration file that will override the default power management behavior) and enter the following:

#!/bin/sh

/sbin/iwconfig wlan0 power off

above exit0, then save gedit, close and reboot.
Thanks

After you entered

gksudo gedit /etc/pm/power.d/wireless

and you entered your password a balnk file opened and that is where you put

#!/bin/sh

/sbin/iwconfig wlan0 power off

right? then you saved the gedit text file closed and rebooted?
Thanks

Since you are using your internal WiFi card make sure that in Network Manager under Preferences your wireless interface is wlan1. This could be the issue. Sometime this can get changed somehow.
